K 波段串馈微带贴片天线设计分析

Design of a Series-Feed Microstrip Patch Antenna at K-band

摘要: 本文介绍了矩形微带天线的特点、原理以及设计方法，设计了1?16 元矩形贴片组成的串馈天线阵，通过对各微带单元进行同相馈电，同时在馈电网络中利用阻抗变换对天线的阻抗进行匹配，并运用天线仿真软件Ansoft HFSS对此天线进行了仿真分析，获得了较好的辐射特性。

Abstract: The characters, the principle and the design considerations of the rectangular microstrip patch antenna areintroduced in the paper. A 1x16 series-fed microstrip antenna array is designed. By feeding inphase to the microstrip cell. Usingtransformer to match impedance. And by use of the software Ansoft HFSS , the antenna array is simulated. The result isconsistent to theory.
