| 摘 要： | 提出一种新型光子带隙(PBG)结构微带贴片天线。在同轴线馈电型微带贴片天线的接地板上蚀刻出新颖PBG结构,通过数值仿真得到有效提高增益的结构。实际制作了PBG结构微带天线,并实测了天线特性参数。数值结果和实验结果进行了比较,取得了较为一致的结果.实测天线增益达8.8dB,比无PBG时提高约3dB,验证了该PBG结构的有效性。

| Abstract: | This paper proposes a new PBG structure for microstrip patch antenna. A new PBG structure is etched on the ground plane of a probe-fed microstrip patch antenna. An effective structure for enhancing the antenna gain is obtained by simulations. Such a PBG structure microstrip patch antenna is fabricated and measured. Numerical results are compared with the measured ones, showing good agreement. The measured gain reaches 8.8dB, which is about 3.2dB larger than that without PBG, verifying the validity of the PBG structure. |
