Realization of a Dual-Polarized Slot Array Fed by Multi-LayerCorporate Feed Waveguides

在60 GHz频段，设计了一种双极化16×16单元缝隙阵列，采用四层公司波导馈源。在59~GHz范围内，两个输入端口之间的隔离度超过60dB；在60.3~63 GHz范围内，对水平线极化和垂直线极化，估计天线效率都超过80%。建立了在双极化波导缝隙天线中实现高隔离度、高交叉极化鉴别率的设计方法。

A Dual-Polarized 16x16-element Slot Array with Four-Layered Corporate Waveguide Feed is designed in the 60 GHz-Band. A very high isolation of more than 60 dB between two input ports is simulated over the range of 59 ~ 64 GHz, and a very high antenna efficiency of more than 80% is estimated over the range of 60.3 ~ 63 GHz for both horizontal and perpendicular linear polarizations. The design method to achieve high isolation, high XPD (Cross Polarization Discrimination) in dual-polarized waveguide slot antenna is established.
