| 摘 要： | 本文论述了小型圆极化微带天线提高方向图前后辐射比的实现途径.文中采用在微带贴片背后附加EBG结构作为微带天线的地面,并在EBG结构地面周边加齿的新方法来提高小地面情况下微带天线方向图的前后辐射比,并对设计出的微带天线电特性进行了测量,测量结果说明该方法对提高小型微带天线方向图的前后辐射比是非常有效的.

| Abstract: | This paper deals with the method to raise the front to back(F/B) ratio on the pattern for the circularly polariged microsyrip antenna patch in small size.Here the EBG construction on the patch opposite plane is adopted to be the ground and the continual tooth around the circumambient edges of the EBG ground are made,so that the F/B is increased for the patch ground in small size.The electric parameters of the designed patch are measured.The experimental results shows that this method is effective. |
