ANALYSIS AND DESIGN OF A DUAL-POLARIZED MICROSTRIP ANTENNA ARRAY WITH PARALLEL CORNER FEEDING
并行角馈双极化微带天线阵的分析与设计

In this paper, parallel corner feeding with two ports is proposed to realize the high isolation, dual-polarized microstrip antenna. A novel dual-polarized feedline network is designed for the array. A method of analysis is developed, which is based on the multiport network model, the cavity theory, the segmentation technique and the desegmentation technique. A one-layer coplanar microstrip antenna array at 6GHz band is designed. The measured isolation between two feeding ports reaches -50dB, which is much better than those of one-layer dual-polarized arrays commonly used.
