摘要

介绍了一种新型贴片天线系统，该系统具有完美磁导体(PMC)衬底和光子带隙(PBG)覆盖层。研究了这种天线的阻抗、辐射方向图和指向性。数值计算结果表明，在PMC结构和PBG覆盖物的存在下，贴片天线的指向性得到了显著改善。并给出了改善的物理原因。

High-directivity patch antenna with both perfect magnetic conductor substrate and photonic bandgap cover

A new patch antenna system, which has both a perfect magnetic conductor (PMC) substrate and a photonic bandgap (PBG) cover is introduced. The impedance, radiation pattern, and directivity of such an antenna are studied. The numerical results show that the directivity of the patch antenna is improved dramatically in the presence of the PMC structure and the PBG cover. The physical reasons for the improvement are also given.
