摘要
设计了适用于K u波段的宽频带高隔离度双线极化4元微带贴片天线阵。用商业应用软件IE 3D对天线电特性进行仿真计算,并制作了实验模型。测量结果与仿真结果吻合良好,两馈电端口驻波小于2的阻抗带宽分别为21.56%与22.58%,隔离度高于32dB,实测增益12.8dB i。
A Ku-band dual-polarized and 4-element micro-patch array antenna is presented. The proposed antenna is analyzed by the simulator of IE3D. The measured results agree well with the simulated ones. The bandwidth at two ports is about 21.56% and 22. 58% （for VSWR less than 2.1） respectively. The isolation between the two ports is better than 32dB across the entire operating bandwidth. The measured gain is about 12.8dBi.
