双极化共馈波导缝隙阵列天线专为 60GHz 频段而设计。为了实现双极化工作，采用了十字形辐射槽和多层馈电结构。两种偏振的反射带宽分别为 5.0% 和 8.1%，VSWR 小于 1.5。在5.0%的宽带宽下，两种极化的天线效率均超过70%。此外，两个偏振之间可实现超过 50 dB 的高隔离度。
A dual-polarization corporate-feed waveguide slot array antenna is designed for the 60GHz band. In order to realize the dual-polarization operation, the cross-shaped radiating slots and the multi-layer feeding structure are employed. The reflection bandwidths of the two polarizations are 5.0% and 8.1%, respectively, for VSWR less than 1.5. The antenna efficiencies of two polarizations are over 70% at a broad bandwidth of 5.0%. Also, a high isolation over 50 dB is achieved between the two polarizations.
