摘　　要：提出了1种具有二维光子晶体带隙结构的微带贴片天线。光子晶体是1种人造的电介质结构在空间上的周期性分布,本文采用的方法是在微带贴片天线介质基片中引入周期性分布的空气孔,并且针对不同的孔径大小对天线的增益特性进行了研究和比较。本文采用模拟仿真软件HFSS对这些结构进行了模拟仿真,仿真结果表明PBG结构能够有效地提高微带天线的基模增益特性,同时可以抑制天线的高阶模及表面波的产生。This paper proposed a microstrip patch antenna based on two-dimensional photonic crystal structure.Photonic crystal,is a artificial periodic dielectric structure.In this aritcle,the periodical distributed air cylinder is introduced into the substrate of the antenna,and the antenna＇s gain varied with the differences of the radius of the air cylinder was studied.Using the simulation software named HFSS to simulate these structures,it shows that the PBG structure is helpful for the gain of work frequency of the antenna,and also for the suppression of the generation of surface wave.
