Abstract

Abstract : A novel topology for designing 60 GHz duplexers is presented. Both the receiver (Rx) and transmitter (Tx) filters of the duplexer, which were constructed using dual‐mode substrate‐integrated waveguide (SIW) cavities, can exhibit a single‐sided transmission zero. The transmission zeros were arranged to achieve high channel isolation and frequency selectivity. The results confirm that the fabricated duplexer can achieve an Rx/Tx isolation higher than 30 dB.
