基于人工磁导体的低剖面高增益宽带天线
A Low-Profile High-Gain Broadband Antenna Based on AMC
摘要
Abstract
A high-gain broadband antenna based on artificial magnetic conductor metasurface(AMC-MS)is proposed.The antenna is composed of an AMC-MS and a microstrip patch antenna.By using the in-phased reflection characteristic of the AMC-MS,the backward radiation of the antenna is reflected and superimposed with the forward radiation,thus improving the gain.The overall size of the antenna is 0.6 λ0×0.6 λ0×0.12 λ0(λ0 represents the wavelength corresponding to the resonant frequency).Experi-mental results demonstrate that within the frequency range of 4.55～6.1 GHz(27.7%),the peak gain of the antenna is 8.4 dB.Compared to the method of using perfect electric conductor(PEC)to enhance the gain,the profile is reduced from 0.37λ0 to 0.12λ0.The excellent performance including low profile,small size,high gain,and low cost makes it a potential candidate for the application of WLAN communication.关键词
