Abstract :
For the antenna duplexer composed of metallic gratings, results of theoretical and experimental studies are presented. A 94 GHz device tested at a low power level has provided the transmit-receive isolation -45 dB; the transmission loss did not exceed -0.1 dB within /spl sim/4% frequency bandwidth.
