摘要

This paper presents a new substrate-integrated-waveguide (SIW) cavity-backed antenna array with dual-polarization monopulse radiation patterns. The monopulse comparator is realized by using SIW magic Tee that is directly fed by the WR-15 waveguide for wide phase balanced bandwidth. The radiating part is implemented by using aperture coupled cross-shaped patches that are enclosed by metallized cavity. In order to realize dual polarizations with high isolation, two independent monopulse feed networks are designed in two different layers and positioned orthogonally to feed the array. Taking advantages of good performance of the SIW-based magic Tee, the monopulse antenna array shows good performance including stable sum and difference patterns with high null-depth from 57.5 GHz to 64.2 GHz.
