摘要:

EBG（电磁带隙）结构已在微带贴片天线中得到广泛的应用。本文采用EBG结构对传统贴片天线进行了改进。使用基于有限元法（FEM）的软件模拟并比较了不同EBG结构对贴片天线性能的影响。结果表明基于基底打孔型方形孔EBG结构的贴片天线的性能最佳，其增益、带宽和输入回波损耗都得到了较大的改善。

Effect of Different Eletromagnetic Band Gap Structures on the Performance of Microstrip Antenna

()

Abstract:

The Electromagnetic Band Gap(EBG) structures have found wide application in microstrip antennas.The enhancement of microstrip antenna performance using EBG structures is investigated in this paper.The influence of three different kinds of EBG structures on a conventional patch antenna is simulated using a software based on FEM(Finite Element Method).Results show that different EBG structures have different effects on the patch antenna.The performance such as gain,bandwidth and return loss of the conventional patch antenna is improved greatly with one of the EBG structures.

Key words: microstrip antenna EBG FEM performance comparison
