介绍了新型电磁 (光子 )晶体贴片天线的研究进展 ,尤其是几种新型光子晶体贴片天线。这些光子晶体贴片天线采用基底钻孔、地面腐蚀、加高阻抗表面以及基底上表面腐蚀等方法在贴片天线中加入光子晶体结构 ,改善了以高介电常数介质为基底的贴片天线的性能 ,也为贴片天线集成在微波电路上开辟了途径。光子晶体贴片天线这种集低剖面 ,易集成与良好辐射性能于一身的新型天线 。

The development of novel patch antenna using photonic band gap structures are reported. Some novel patch antennas using photonic band gap structures are discussed. The methods of drilling a periodic pattern of holes in the substrate, etching a periodic pattern of circles in the ground plane, using a triangular or square lattice of metallic pads connected to ground with vias and etching metal units on the layer of substrate are used to improve the performance of patch antenna by adding photonic band gap structures in it. These lead to the possibility of integrating antennas on integrated circuits on high dielectric constant substrates. The characteristics of low profile and easy integration without losing performance will make this novel patch antenna applied in many areas.
