Portable Reader Design with Carrier Suppression
In UHF (Ultra High Frequency) RFID (Radio Frequency Identification) systems Rx (Receiver) is usually isolated from Tx (Transmitter) by a circulator or a directional coupler. Since tags become more sensitive in order to improve reading distance, the relatively poor isolation of 20dB - 30dB limits the tag to reader link. A way to improve a directional coupler's isolation is to mismatch the unused port to generate a carrier cancelling...
