A high isolated coupled‐line passive circulator for UHF .

A high isolated coupled‐line passive circulator for UHF .

A coupled‐line passive circulator is proposed for improving the TX/RX isolation of the UHF radio frequency identification (RFID) reader. The increased isolation is realized by generating and adding the canceling signal to the leakage.
