摘要
提出了一种Ku波段的新型宽频带微带天线,改进了H形槽耦合微带天线的结构,在辐射贴片和反射板上均开H形槽以展宽工作频带。用商业应用软件IE3D对天线电特性进行仿真计算,并制作了实验模型。实验测量结果与理论仿真结果吻合良好,其电压驻波比(VSWR)小于2的阻抗带宽达到了27.4%,交叉极化电平小于-20 dB。
A novel wideband Ku-band microstrip antenna by embedding an H-slot in the radiation patch and the ground plane is presented. The H-shaped aperture-coupled H-slot patch antenna is developed as an aperture-coupling structure, and is used to improve impedance bandwidth. The proposed antenna is analyzed by using the simulator IE3D. The measured results agree well with the simulated results. A bandwidth about 27.4% for VSWR less than 2 ： 1 and cross polarization less than-20 dB are obtained.
