摘要

提出了一种新型圆极化双馈微带贴片天线，并利用电磁带隙(EBG)结构提高了天线的效率和带宽。微带贴片是具有倒角和等臂长交叉槽的正方形。它由50Ω两条微带线馈电。该天线工作在厚度为0.76 mm、相对介电常数(εr)为2.92的Taconic RF-30衬底上。该衬底有几个真空孔用于实现EBG。采用Ansoft HFSS软件对所提出的结构进行了设计和仿真。研究了改变贴片天线的参数对天线性能的影响。

Design of a novel circularly polarized microstrip patch antenna using EBG structure

In this paper a novel circularly polarized dual-feed microstrip patch antenna is proposed and also Electromagnetic Band-Gap (EBG) structures are utilized to enhance the antenna efficiency and bandwidth. The microstrip patch is a square with a chamfered corner and a cross-slot of equal arm lengths. It is fed by 50Ω two microstrip lines. The proposed antenna is designed to work on a substrate Taconic RF-30 that has a thickness of 0.76 mm and relative permittivity (εr) of 2.92. This substrate has several vaccum holes for realization EBG. The proposed structure is designed and simulated by Ansoft HFSS software. Effects of varying the parameters of the patch antenna on the performance of the antenna have also been studied.
