| 摘 要： | 给出一种利用缺陷地结构实现天线小型化的方法,将缺陷地结构用于微带天线小型化的设计中,并对缺陷结构的尺寸与天线小型化的效果进行了分析。采用Ansoft HFSS进行仿真,在谐振频率为2.45 GHz的微带贴片天线的介质板上引入一种新型缺陷地结构,比较加入缺陷地结构前后天线的各项参数。其结果表明,该结构在保证天线性能的情况下,天线体积减小了30%以上。

| Abstract: | An effective microstrip antenna miniaturization method is proposed for microstrip antenna array using defected ground structure etched on the ground of the microstrip antenna. The relationship between the performance of the antenna and the size of the DGS is studied. HFSS simulation shows that the size of the antenna with DGS is more than 30% smaller than that without it,and the performance of the antenna with DGS indicates that the DGS is effective in antenna miniaturization. |
