覆盖高εr材料微带天线的研究

内容简介：采用高介电常数(εr=38)的陶瓷材料制作矩形微带天线，体积缩小了很多，但增益下降。若用更高εr材料的覆盖层，在900MHz和1．8GHz频率实验表明，增益得到明显提高。

Abstract：Owing to the fabrication of the rectangular microstrip antenna adopts the ceramic material of high permittivity εγ=38,its size will be significantly reduced. Experiments on 900MHz and 1. 8GHz indicate that the antenna gain for optimum superstrate layers can be greatly enhanced ,which will not be affected by the reduction of dimension.
