摘要

采用矩量法对L型探针馈电的微带天线进行仿真研究,对比分析了L型探针的2种传统等效方式,得出细带和立方柱体不能用于等效L型探针馈电,文中采用直接剖分对L型探针进行建模。通过对L型探针馈电矩形微带天线进行参量分析,得出当空气介质厚度大于0.8λ0时,采用L型探针馈电可以使天线相对带宽达到30%以上(S11<-10dB);分析了L型探针高度和臂长对天线带宽的影响,通过判断电抗的容感性,调节L型探针的高度和臂长,可以有效改善天线带宽。最后设计了一副频率覆盖通信卫星下行传输信号频段3.2~4.4GHz的微带天线。

Abstract

The L-shaped probe feed was studied by the way of MOM. In this paper, the L-shaped probe was meshed directly as thin strip and cube mold can not be used to analyze the L-shaped probe. A parametric study on the rectangular patch antenna with L-shaped probe feed was presented. It was found that the antenna attained above 30% impedance bandwidth(S11 <-10dB) when the air substrate was thicker than 0.8λ0; the effect on the impedance bandwidth made by the height and the arm of L-shaped probe was analyzed. The method of bandwidth enhancement was presented, the reactance being capacity or not which determined how to adjust the height and the arm of L-shaped probe. At last, a micro-strip antenna was designed to operate over the range of 3. 2GHz ~ 4. 4GHz that can be used for broadcast television and VSAT applications.

Key words： L-shaped probe; capacity; MOM
