基于特征模的宽带高增益超表面天线设计
Design of Broadband and High Gain Metasurface Antenna Based on Characteristic Mode Analysis
摘要
Abstract
In the paper,a broadband and high gain metasurface antenna is proposed for meeting the demand of high performance antenna for C-band military equipment.The antenna uses the metasurface directly as the radiator and combines with the high-impedance-surface to achieve the high performance of broadband high gain with low profile and miniaturiza-tion.The equivalent circuit of the metasurface antenna is proposed.Characteristic mode analysis is applied to demonstrate the design process of an antenna.The processing cost,which antenna engineers concerned,is analyzed.The prototype an-tenna is processed and tested.The measured results show that the reflection coefficient is less than-10 dB and the peak gain is 9.9 dBi in the band from 5 GHz to 7.5 GHz(40%),and the measured results are in good agreement with the simula-tion results.关键词
