摘要
提出了一种在接地板和辐射贴片同时开H形槽的新型宽频微带天线。设计了一个工作于Ku波段的微带天线。采用时域有限差分(FDTD)方法对该天线的电特性进行了仿真计算,并制作了实验模型。测量结果表明,该天线驻波(VSWR)小于2的相对阻抗带宽达到了37.6%,交叉极化电平小于-17dB。
A novel wideband H-shaped aperture-coupled H-slot microstrip antenna is proposed in this paper. As an example, this kind of microstrip antenna operating at Ku frequency band is designed and analyzed by using the finite-different time-domain （FDTD） method. A experimental prototype is also made. The measured resuits show that the prototype antenna could achieve 37. 6% bandwidth for VSWR less than 2：1 and cross polarization less than-17dB.
