摘要

本文提出了一种新型的由方形环形和方形金属贴片组成的多谐振单元微带反射阵列。为了减小馈电源的阻塞效应，选择了维瓦尔第天线作为馈电源。设计了一个7×7单元反射镜，并将维瓦尔第天线放置在反射镜的中心上方。仿真结果表明，该天线在5.8 GHz工作频率下的最大增益为18.82 dBi, 1- dB增益带宽为18.5%。

A Novel Microstrip Reflectarray Antenna with Ultra-Wideband Feed

This paper presents a novel microstrip reflectarray utilizing multi-resonant element, which is comprised of a square ring and a square metallic patch. To decrease the blockage effect of the feed source, a Vivaldi antenna is selected as the feed. A 7×7 element reflectarray is designed, and the Vivaldi antenna is placed above the center of the reflector. The simulation results show that maximum gain of the proposed antenna is 18.82 dBi at the working frequency 5.8 GHz and has 18.5% 1- dB gain bandwidth.
