采用基片钻孔法在微带天线中加入PBG结构,设计一种工作频率为2.4Hz的PBG结构的切角微带天线。通过仿真软件建立天线模型并对其仿真,最后与采用传统结构的微带天线进行对比,证明光子晶体结构的新型天线在拓展天线带宽以及降低输入回波损耗等方面具有较大的优势,同时也指出此PBG结构微带天线的不足以及今后的改进方向。
The substrate drilling method was used to add the PBG structure to the microstrip antenna, and a kind of cutting angle microstrip antenna with PBG structure operating at 2.4Hz was designed. The antenna model is established by simulation software and compared with the microstrip antenna with the traditional structure. It is proved that the new antenna with the photonic crystal structure has greater advantages in expanding the antenna bandwidth and reducing the input return loss. At the same time Pointing out the shortcomings of this PBG microstrip antenna and the future improvement direction.
