摘要

本文研究了一种改进椭圆贴片微带天线(EPMA)在FR4衬底上的辐射性能。采用小偏心值的椭圆微带天线，利用单馈点产生圆极化。利用模态腔模型和电路理论概念建立了天线的理论模型。天线的排列分别在5.75 GHz、6.375 GHz、8.25 GHz和13.625 GHz四个频率上谐振。前两个频率间隔很近，可以提高带宽。结果还表明，在天线结构上也获得了紧凑性。详细介绍了天线的设计方法和理论结果，并进行了系统的讨论。

Design and analysis of frequency agile elliptical patch microstrip antenna

This paper presents the radiation performance of a modified elliptical patch microstrip antenna (EPMA) simulated on FR4 substrate. The elliptical microstrip antennas with small values of eccentricity have been employed to produce circular polarizations (CPs) with the use of single feed point. Theoretical model for an antenna is developed using modal cavity model and circuit theory concept. The arrangement of antenna resonates at four frequencies 5.75 GHz, 6.375 GHz, 8.25 GHz and 13.625 GHz, respectively. The first two frequencies are closely spaced and give an improved bandwidth. The results also show that the compactness is also obtained in the antenna structure. Details of the antenna design approach and theoretical results are presented and discussed systematically.
