摘要

本文提出利用双端口的串行角馈方形贴片实现双极化，并设计了一种共面的双极化馈线网络．综合运用多端口网络模型、腔模理论和分片法，给出了单端口、双端口天线单元和双极化天线阵列的理论分析．本方法计算简便，适合于工程应用．实际设计了一副６ＧＨｚ频段的单层天线阵，实验测量的双端口隔离度达－４１ｄＢ，其性能明显优于通常的单层双极化微带天线阵．该面阵结构简单、馈线网络较小，且易合并成更大规模的双极化天线阵

Abstract

The serial corner feeding of a square patch with two ports is proposed to realized the dual polarized microstrip antenna.A novel coplanar dual polarized feedline network is designed for the array.A method of analysis is developed

which is based on the combination of multiport network model

cavity theory and segmentation technique.The one port and two port antenna elements and the dual polarized array are studied in order.A single layer microstrip array at 6GHz band is designed and manufactured.Its measured isolation reaches -41dB

which is much better than that of the single layer dual polarized arrays commonly used.The present array module is of simple structure

small feedline network and is easy to be further combined to form larger dual polarized antenna arrays.
