Compact waveguide monopulse comparator at Ka-band for monopulse tracking

摘要

In this paper, a compact waveguide monopulse comparator at Ka-band for monopulse tracking is presented. Simulated results show a bandwidth of nearly 6% for a return loss of better than 10 dB, an isolation of better than 40 dB between the ports, and a null depth better than 40 dB. There is an imbalance of +0.1/-0.8 dB and 1° in magnitude and phase respectively at the output ports.
