Abstract

A design strategy using Photonic Band Gap (PBG) structure on ground plane to achieve wider bandwidth for patch antenna is presented. It is found that, the impedance bandwidth has improved from 3.72% to 31.9 % at centre frequency 9 GHz after adding PBG on the ground plane. The antenna has multi band operations at 5, 6 and 9 GHz. E-Plane and H-plane radiation patter is satisfied within this bands.

基于PBG结构的小贴片天线在不同无线应用中的带宽增强

提出了一种利用地平面光子带隙(PBG)结构实现贴片天线更宽带宽的设计策略。结果表明，在中心频率9ghz处加入PBG后，阻抗带宽从3.72%提高到31.9%。该天线在5、6和9 GHz具有多频段操作。在该波段内满足e面和h面辐射方向图。
