摘要:

在普通微带缝隙天线介质基板内引入光子晶体结构,设计了一种基于PBG结构的多频微带缝隙天线,采用平面波展开法对该天线进行了理论分析,并用HFSS 10.0对该天线进行了仿真。与传统的微带缝隙天线相比,PBG结构的引入改善了微带缝隙天线的辐射特性及多频工作性能。该天线可以用于跳频通信系统中。

Abstract:

Based on the conventional microstrip slot antenna,a new PBG substrate for multi-frequency microstrip slot antenna is designed. The antenna is theoretica11y analyzed by using the plane wave method,and numerical simulation is performed for this antenna with Ansoft HFSS 10.0. Comparing with the conventional microstrip slot antenna,both the radiation and multi-frequency characteristics of the proposed antenna are improved.This kind of antenna can be used in hopping frequency communications.
