ANALYSIS AND DESIGN OF A DUAL-POLARIZED MICROSTRIP ANTENNA ARRAY WITH PARALLEL CORNER FEEDING
-
摘要: 本文提出利用双端口的并行角馈实现双极化天线,并设计了一种新的双极化馈线网络。综合运用了多端口网络模型、腔模理论、分片法和补片法,给出了各天线单元和双极化馈线网络的理论分析方法。实际设计了一副6GHz频段的单层共面的四元天线阵,实测的双端口隔离度达-50dB,其性能明显优越于通常的单层双极化微带天线阵列。Abstract: 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.
