Working on a project with RFID reader, tags, and antennas. I want to be able to scan through 50+ antennas and read any and all RFID tags that are within range.
To do this i thought of using: 1 RFID reader, 16 multiplexers, counter, and the antennas.
The idea was to connect the antennas to the multiplexers and have the counter or adder scan through all the antennas 1 by 1 to check for tags. This would then be fed to the RFID reader.
The problem:
If i try to connect more than 4 antennas the read distance goes down dramatically. It actually goes down 1/2 the distance with each additional antenna.
Anyone have any suggestions on how i would be able to setup an array of antennas that feed info to 1 RFID reader?!
