Abstract

This paper presents a low-profile patch antenna with dual-axis wide-beam characteristics. The antenna includes a microstrip patch antenna and four parasitic patch elements. The study demonstrates that both the E-plane and H-plane beams can be extended by strategically placing these parasitic patches. The length and distance of these parasitic patch elements play a crucial role in achieving the desired wide-beam characteristics. A prototype antenna operating at 5.8 GHz is fabricated and measured in an anechoic chamber to validate the concept and design parameters. The measured results confirm the extension of half-power beamwidth in the E-plane to 123 $^{\circ}$ (133%) and in the H-plane to 120 $^{\circ}$ (153%).

使用寄生贴片元件的低剖面宽波束宽度微带贴片天线

本文介绍了一种具有双轴宽波束特性的扁平贴片天线。该天线包括一个微带贴片天线和四个寄生贴片元件。研究表明，通过战略性地放置这些寄生贴片，可以扩展 E 平面和 H 平面的波束。这些寄生贴片元件的长度和距离对实现所需的宽波束特性起着至关重要的作用。为了验证这一概念和设计参数，我们制作了工作频率为 5.8 GHz 的原型天线，并在电波暗室中进行了测量。测量结果证实，半功率波束宽度在 E 平面扩展到 123 ∘ $^{circ }$ (133%)，在 H 平面扩展到 120 ∘ $^{circ }$ (153%)。
