Times-7 A8060 slimline doorway antenna

December 22, 2016 4:41:58 PM EST

Today, a customer came in asking if the Times-7 UHF RFID antenna, part # A8060 was suitable for both FCC & ETSI use.  The answer is that there are typically TWO different models for each and every RFID antenna, one for FCC and one for ETSI.  The only exception is when an antenna is designed as a “wide-band” model that would cover both FCC & ETSI.  In the case of the Times-7 model A8060, there are two different antenna models:

This anenna is super small, and suitable for use in doorways.  It measures in at only 3 inches wide x 25 inches long.  The only drawback is that it is linearly polarized (vs. circular) so it may not work well in applications where RFID tag orientation is not consistent.  If any of our readers has any questions on this, or any other RFID antenna, simply email me at: sales@arcadianinc.com

Recently, there was some confusion regarding the all new B6031 antennas introduced by Times-7. These are the next evolution of the A6031 series of FCC and ETSI 11x8.5 inch, circularly polarized panel antennas for 865 and 915 MHz UHF RFID.

I wanted to take a moment to explain what happened with these part #’s. Times-7 had a typo on their original datasheet, and did not know it (and neither did we.) That has since been corrected by Times-7, and by Arcadian Inc. over the past 48 hours.

The correct information is below, and this is now reflected on both the T7 and arcantenna.com websites. Please ensure that your records have been updated as well.

• B6031-71827 is the 902-928 MHz *FCC* version of the antenna.  LINK HERE for FCC.

• B6031-71828 is the 865-867 MHz *ETSI* version of the antenna.  LINK HERE for ETSI.

The corrected datasheet can be found on the above web links.

My apologies for the confusion,

Mike

An RFID system integrator came in this afternoon complaining that after Intermec discontinued antenna part # 1309-57-0087, they had no equivalent high-gain RFID antennas to offer their clients.  

The 1309-57-0087 antenna has the following specifications: 

  • Size: 14.6 x 14.6 inches & 4.4 Lbs.
  • Frequency Range: 902-928 MHz (UHF, FCC, RFID)
  • Gain: 10 dBic
  • Polarity: RHCP/right hand circularly
  • Rating: IP67 - outdoor rated
  • Beamwidth: 60 x 45 degrees at 3 dB

Here is what we suggested (below) If you are in the same situation, these are models that you should consider: 

A6034: (12x30 inches) http://www.arcantenna.com/a6034-70809-30x12-inch-circularly-polarized-slimline-rfid-antenna-fcc.html

A6034 SlimLine Antenna  SlimLine-A6034S

A6034S: (15x15 inches) http://www.arcantenna.com/a6034s-71003-15x15-inch-circularly-polarized-slimline-rfid-antenna-fcc.html

These models offer 9 dBic of gain (vs. 10 dBic)  but they do have very good propagation, and typically are your best choice to replace the Intermec models.

Zebra AN480 RFID Antenna Mounting Options

April 5, 2016 11:48:58 AM EDT

I had a customer contact me this morning, very frustrated that he could not find a way to mount the Motorola / Zebra AN480 antennas he had purchased for his RFID project.  I told him that the AN480 antennas from Zebra have a customize mounting bolt pattern, specifically so you can’t buy mounts anywhere else – BUT they never came out with any decent mounts.  So, here is what I recommended to him, and to you... 

 

Purchase RFMAX part # S9028PCx96RTN (same exact antenna, IP54 rated, but with pre-attached 8 foot/96 inch cable & RPTNC connector) http://www.arcantenna.com/s9028pcl96rtn-s9028pcr96rtn-10x10-inch-ip54-rated-circularly-polarized-rfid-antenna-with-4-mounting-studs-fcc.html

 

Or, purchase RFMAX part # PAx90209H-FNF (same antenna, IP67 rated, with fixed N-Female connector) http://www.arcantenna.com/pal90209h-fnf-par90209h-fnf10x10-inch-ip-67-rated-circularly-polarized-antenna-fcc.html

 

These two antennas can utilize the HEAVY DUTY mount, which locks firmly in place, RFMAX part # HDMNT: http://www.arcantenna.com/hdmnt-heavy-duty-aluminum-mounting-bracket-wall-or-mast-mount.html

 

Or, they can utilize our fully articulating, easy to install EZM6 mount: http://www.arcantenna.com/fully-articulating-die-cast-wall-or-mast-mounting-kit-for-2-or-4-stud-panel-antennas.html

Do I have to use opposing polarity RFID antennas?

October 28, 2015 11:49:04 AM EDT

RFMAX S9028PC

Today, we had a client contact us because they had an installation of RFMAX S9028PCx96RTN circularly polarized RFID antennas that was suffering from poor performance.  The use case was a portal set up in a hallway to track employees coming and going from a job site.  The RFMAX 8.5 dBic, 10x10 inch,  circular polarized RFID panel antennas were set up on both sides of the portal (which was about 4 foot wide) and the antennas were arranged such that they were DIRECTLY opposite on another.

 

Apparently, each time they turned on the Impinj R420 RFID reader, and activated the antenna ports, they were having major trouble reading RFID tags.  However, when they de-activated all of the antennas on one side of the portal, they experienced INCREASED performance, thus leading us to belive that the antennas from one side of the portal were interfering with those on the opposing side.  After investigating, we discovered that all of the circular polarized RFMAX antennas they were using were of the same polarity, in this case LHCP.

 

For maximum performance, RFID antennas should not be positioned directly across from each other.  They should always be off-set from one another, if at all possible.  In addition, when antennas MUST be positioned directly across from each other, in close proximity (< 12-15 feet apart) that is the only time that opposing polarities SHOULD be used.  In this use case, it is quite possible that the antennas are interfering with one another and cancelling out signal.  So, there are two possible corrective actions:

1. Remove all of the antennas from one side of the portal and replace with antennas of opposing polarity, in this case RHCP antennas.

2. Without swapping out the antennas, they can try simply changing the articulation of each set of antennas, if the mounting hardware allows this.  For these 10x10 inch antennas, I'd recommend using the fully articularing RFMAX EZ-M6 antenna mounts.

 

To clarify, what I mean is this…take all of the antennas on the left side of the portal and articulate / position them at a slight angle towards the outside door.  Next, take all of the antennas on the right side of the portal and articulate / position them at a slight angle away from the outside door.  By not having the antennas facing each other directly, they should be able to eliminate a significant amount of the interference.

Times-7 71757 mounting plate for A5010 antenna

September 28, 2015 7:45:27 PM EDT

My name is Mike Crudele of Arcadian Inc.  We are an antenna specialty distributor, with a focus on RFID, and our stocking support location is located in Phoenix, AZ.  Today, I received a request for the 71757 universal antenna mounting plate from Times-7.  That unit was never fully released to production, and likely will never be.  The reason is that the Time-7 model A5010 antenna is being re-configured as we speak with a built in 100 mm VESA backplate, eliminating the need for any additional "transitional" mounting plates.  These units will be available through Arcadian Inc. on December 1, 2015.   However, for the time being, this antenna can in fact be mounted without this plate, or you could simply utilize a different antenna.  Contact me directly, and I’ll explain how to do it. 

Personally, I'm very familiar with the A5010, 902-928 Mhz, circularly polarized, 10x10 inch RFID panel antenna, and I'd be happy to work with any potential client to design in this ultra low-profile RFID antenna, into your upcoming applications.  Please email me and let's set up a time to discuss your requirement, and how I can help.

I wanted to post this review that I received for the RFMAX brand hand-held UHF RFID antenna POWER MAPPER.

 

Check out the Device HERE.

 

The RFMax Power Mapper is a compact tool to determine the radiation pattern for an installed UHF RFID transceiver system. The device measures 3 x 4 x 1.5 inch (including the antenna) and weighs about 2 ounces. It uses a linear (small whip) antenna. This antenna is mounted on a standard SMA female bulkhead connector and can be removed. When removed, the height of the device goes down from 4 inches to 2.75 inches. The instrument is equipped with a toggle switch which adds 12dB attenuation when activated, which is to be used for measurements in near vicinity to a reader antenna, to prevent the meter from pegging out.

 

The instrument is based on an analog moving-coil meter. The whole system derives its power from the RF field, meaning no batteries are necessary. Test results Firstly, the instrument was tested with a standard 9dBic antenna fed by a 1 watt PEP RFID reader. The mapper shows the boundaries of the field well, although an actual RFID tag reads a bit farther than the minimum meter indication. As long as the user is aware of this phenomenon, this is a good tool to get a quick impression of the functionality and proper operation of an RFID reader installation. Also, the tool turned out to be very helpful in determining the circularity of the antenna pattern; by rotating it around its axis while being held at antenna bore sight, this works very well. As it turns out, the sensitivity of the instrument does not change much from 850 to 930 MHz, so it can be used for both ETSI and FCC installations without the need for re-calibration.

 

Of course, for an instrument working according the principle of a passive RF detector, it makes a difference in sensitivity whether the reader transmitter is modulated or not (the latter defined as constant-wave), as the instrument does not have a peak-hold function; it only records the average amplitude of the transmitted signal. To be more specific; the lower the transmitted duty-cycle of the emitted signal is, the lower the indication on the instrument will be with all other things being equal. So if one wants to comparative measurements and/or more absolute measurements, the RFID reader transmitter should be switched to constant-wave operation when mapping the field with this device. As a second test, the 12dB attenuator was activated, and the results compared against a 12dB decrease in actual transmitted field strength (with the meter attenuator off). This showed us that the 12dB attenuator indeed corresponds reasonably well with a 12dB step in attenuation (within 2dB accuracy which is very good for a low-cost tool like this) As a third test, we also tested the detector output to monitor the detected envelope wave form on an oscilloscope. As it turns out, the detector can follow the modulation transitions without a problem, so the output signal is a good representation of the actual transmitted signal AM envelope.

 

Although we have not tested this yet, the SMA connector on this device would also allow for actual power measurements directly on the coaxial port of an RFID reader, on condition this would be done in combination with an additional RF attenuator. In this way, actual reader output power could be measured, assuming a one-time calibration would be done in the lab first for this instrument. This method could be a good alternative for taking an expensive power meter out on the road (like a Bird 43 and the like) . To summarize: We have found the RFMax power mapper to be an excellent and convenient tool when doing RFID reader installations; it fulfills all promises.

 

Final Thought: This instrument should be a standard part of any RFID installer’s tool box!

Today I was asked...How do I connect an embedded ThingMagic RFID reader module to an external RFID antenna?  

 

Well, at first glance, this may seem complicated since the ThingMagic modules (ie: Nano, Micro, Micro-LTE, M5e, M6e) have a tiny connector, which in fact is an MMCX style RF connector. However, this simply adds a step in the process, but is simple once you know how to handle it.  Here, I'll explain exactly how you make the connection from a ThingMagic embedded RFID module to an RFID panel antenna.

 

Step 1: purchase a small coaxial jumper cable which will take you from the MMCX connector on the embedded RFID module to the antenna cable.  I would suggest part # CA178-RTNCB-MMCX-6.  This is a 6 inch long RG178 type of small diameter coax cable with an MMCX connector on one end (to connect to the RFID module) and a Reverse Polarity TNC Female (bulk-head) connector on the other end.  This bulk-head connector will protrude out of your device or enclosure and provide you with the same type of connector that you would typically find on an industry standard RFID reader such as the ThingMagic M6, Impinj R420 or Motorola-Zebra FX7500 / FX9500.

 

So, now you have a Reverse Polarity TNC Female (bulk-head) to connect to.  I would suggest utilizing the all-pupose 10x10 inch circularly polarized panel antenna from RFMAX, part # S9028PCx96RTN.  This antenna offers a 70x70 degree beamwidth and 8.5 dBiC gain.  In addition, these antennas include a 96 inch / 8 foot long integrated coaxial cable and RPTNC-Male connector.  if you choose this antenna, I'd suggest you look at the RFMAX mounting kit EZ-M6-Combo.

 

If you have any further questions regarding how to connect an antenna to a ThingMagic embedded RFID reader, don't hesitate to contact us!

RFID Journal Live! 2015 Show Recap

May 13, 2015 7:25:00 AM EDT

Arcadian Launches RFMAX Brand at RFID Live! 2015


It's been several weeks now since the RFID Journal Live! Tradeshow in San Diego, and now that we've managed to catch our breath (at least a little), we can offer a few reflections on 2015's premeire RFID event.

 

To begin with, show attendance was at it's highest level since 2008, and the increase in traffic from the past few years was noticeable. A good sign that business is continuing to recover, and that the RFID space continues to grow. While many attendees were RFID industry insiders and familiar faces, a significant proportion were also end users from virtually every industry imaginable. More good news for the RFID space as a whole, and for growing RFID adoption in general.

 

As for Arcadian, we utilized this years show to launch our new brand of RFID products from RFMAX. Key products shown included RFMAX Passive RFID Antennas and Antenna Cables; RFID Weatherproof Reader Enclosures, and the RFMAX Power Mapper.Traffic to the booth was steady for all 3 days of the event, with plenty of people taking notice of the new RFMAX product line. Interest in antennas and weatherproof enclosures was fantastic, but the RFMAX Power Mapper literally stole the show... in fact, we sold out our entire stock of Power Mappers while we were there! (not to worry if you didn't get yours yet... we've since replenished our stock and have more on the way).

 

Overall, we see interest in RFID applications and products continuing to bloom, and  are thrilled with the response we received for our new RFMAX line. A great show this year all the way around. Our sincere thanks to all of our customers, partners and friends, along with the RFID Journal staff for making this year's RFID Journal Live show one for the books!
