具有不同宽槽数的矩形微带贴片天线多带特性研究

内容简介：主要研究了多带工作的特性,并通过设计矩形贴片微带天线--包含不同数目的并放置在两辐射端的槽, 进行分析. 分析基于MOM仿真软件包, 结论表明一个贴片上有3个槽的天线具有多带特性: 4个振荡频率分别在1. 6, 1. 8, 2. 65, 和4. 83 GHz, 并且具有足够的反射损耗和增益值. 同时证明了带有2对槽的贴片天线(槽分别位于两辐射端)有双带特性, 其振荡频率分别在1. 64和1. 8 GHz, 而且返回损耗和增益值很好.

Abstract：The property of multi-band operation has been studied and investigated analytically through the design of a rectangular patch microstrip antenna having different numbers of wide slots arranged at both the radiating edges. The analyses were carried out using the method of moments simulation software. It is shown that a patch with three slots has a multi-band feature with four resonant frequencies at 1. 6, 1. 8, 2. 65, and 4. 83 GHz and adequate values of return loss and gain. It is also shown that a patch with two pairs of wide slots arranged at both the radiating edges has the dual band feature with resonant frequencies at 1. 64 and 1. 8 GHz and good values of return loss and gain.
