Abstract

The previous single element antenna was made of two separated layers, one for the patch antenna (upper) and the other for the feed-line (below), using proximity feed for a thin configuration. In this time, a novel dual feed antenna with a hole-truncated is proposed for the generation of a compact LHCP (Left Handed Circular Polarization) using a compact equilateral triangular-patch antenna, that one of the microstrip-line feeds is longer than the other for introducing a 90° phase delay. The influence of the hole-truncated that embedded on the patch is investigated to make the patch antenna smaller than the previous antenna. The method of moments (IE3D Zeland Software) is used considering a finite ground analysis. The simulation results show that the patch length decreases by 12.65 % (a = 52.80 mm to a = 46.12 mm) with a gain and axial ratio at 2.5025 GHz being 6.82 dBic and 0.66 dB, respectively. The bandwidth of the hole-truncated antenna, by comparison of the previous antenna is smaller.

空穴截断对移动卫星通信等边三角形天线特性性能的影响

以前的单元件天线由两个分离的层组成，一层用于贴片天线(上)，另一层用于馈线(下)，使用接近馈线进行薄配置。本文提出了一种新型的空穴截断双馈天线，用于使用紧凑型等边三角形贴片天线产生紧凑型LHCP(左手圆极化)，其中一个微带线馈电比另一个长，以引入90°相位延迟。研究了嵌入的孔截断对贴片的影响，使贴片天线的尺寸小于原有的天线。考虑有限地基分析，采用了矩量法(IE3D Zeland软件)。仿真结果表明，在2.5025 GHz时，增益和轴比分别为6.82 dBic和0.66 dB，贴片长度减少了12.65% (a = 52.80 mm至a = 46.12 mm)。与前一种天线相比，孔截断天线的带宽更小。
