Abstract :
Summary form only given, as follows. An integrated W-band passive monopulse comparator network is constructed using four rat-race hybrids, designed using the PolystrataTM 3-D sequential micromachining process. The comparator network has a simulated azimuth null of 44.6 dB and elevation null of 44.4 dB. The network is monolithically integrated with an array of cavity backed patch antennas and diode detectors for measurement purposes. An azimuth null of 31.4 dB and an elevation null of 22.5 dB are measured at 93.5 GHz.
