Arcadian Blog — LHCP

Recently a client approached us about the Alien part # ALR8696-C. They were developing new software and need an antenna that utilized LHCP (left-hand circular polarization), which part # ALR8696-C does not. In response, I have come up with two suggestions, both of which come in LH and RH circular polarizations.   Suggestion 1 RCPL-902-09-SNF: This antenna measures in at 10 x 10 inches and features a gain of 9 dBic, a fixed N-Female connector, and an IP rating of 67.   Suggestion 2 RCPL-902-8-RTM-8: This antenna is the industry standard for passive UHF VHF RFID installations. It measures in...

Q) Is there an antenna that is similar to S8658PL96RTN in FCC frequency? The same connector is needed but we are impartial to the number of studs as long as it fits part # EZM6COMBO.   A) We have multiple parts that work with EZ mounts, below you will find the two recommendations similar to part # S8658PL96RTN…   S9028PCR96RTN (RHCP, four studs): The industry standard antenna for passive UHF RFID installations. Its right hand circularly polarized and measures in at 10 x 10 inches with reception and transmission in the FCC. This part comes with four studs but you...

This morning, I received a call from a client who wanted to understand the pros and cons of using Linear vs. Circularly polarized RFID antennas.  At Arcadian Inc., we've been selling both types of antennas for many years, and we come across this situation often

  Today, we had a client contact us because they had an installation of S9028PCL96RTN circularly polarized RFID antennas that were 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...
