摘　　要：采用时域有限差分法(FDTD)研究光子晶体带隙结构(PBG)对贴片天线性能的影响,设计了一种基于光子晶体结构的贴片天线,通过仿真,与普通贴片天线进行了对比。结果表明,通过添加光子晶体结构能提高天线增益。The purpose of this paper is to analyze the influence of photonie crystal band-gap （PBG） structure to the patch antenna,and the method based on the finite difference time domain（FDTD） was used. We compared two simulated antennas,one of which is based on PBG structure. We found that its gain were improved by adding the PBG structure.
