摘要

本文提出了一种用于毫米波应用的双极化波束形成相控阵天线。孔径耦合天线设计有两个贴片(及其下面的两个堆叠贴片或寄生贴片)，由一条主线通过分岔为这些贴片提供馈电。顶部的补丁比下面堆叠的补丁更大。在这些补丁下，在接地面上为每个偏振创建了两个“I”形的垂直槽(大小不同)。一个是水平极化，另一个是垂直极化。设计的天线工作在28 GHz，垂直极化范围为25 GHz至29 GHz，峰值实现增益约8.3 dBi，水平极化范围为25.9 GHz至29 GHz，峰值实现增益为8 dBi。该天线可以在这些端口之间的隔离30 dB的频带上广泛工作。

A Dual Polarized Millimeter Wave Phased-Array Antenna

In this paper a dual polarized beamforming phased array antenna for millimeter wave application has been presented. Aperture coupled antenna is designed with two patches (and two stacked patches or parasitic patches below them) fed by one main line by bifurcating into two parts for these patches. The top patches are bigger compared to stacked patches below them. Under these patches two "I" shape perpendicular slots (of different sizes) has been created in the ground plane for each polarization. One is for horizontal and another for vertical polarization. The designed antenna operates at 28 GHz with peak realized gain around 8.3 dBi over a band of 25 GHz to 29 GHz in vertical polarization and peak gain of 8 dBi for 25.9 to 29 GHz in horizontal polarization. The antenna can be widely operated over the band with isolation between these ports 30 dB.
