并行角馈方形微带天线研究

A Study of Parallel Corner Fed Square Microstrip Antenna

研究了利用并行角馈的方形贴片微带天线，给出了其输入阻抗特性的一种理论分析方法，导出了其闭合表达式．该方法综合了多端口网络模型、腔模理论、分片法和补片法，充分考虑了并行角馈结构的特点，比简单处理的腔模理论能更准确地用于天线的设计，且计算方便．

The parallel corner fed square microstrip antenna is studied. A method of analysis of input impedance properties is developed, and the closed form expressions are derived. The Multiport network model, the cavity theory, the segmentation technique and the desegmentation technique are combined in the present approach. The characteristics of parallel corner fed structure are fully included in the method. For antenna design, more accurate results can be conveniently obtained from it than those from the cavity theory. The experimental results validate the theory.
