| 摘 要： | 设计了一种双线双圆极化的多层印制板形式的微带天线阵列,采用缝隙耦合和微带线边馈实现天线的双极化,通过开关及圆极化器实现天线的双线双圆极化输出。通过对影响天线性能的各个参数进行优化设计,并加工了天线阵列,天线实测带宽为约15%,天线增益优于17dB。该天线单元结构简单,剖面低,可以作为大型微带天线阵列的子阵进行通信。

| Abstract: | A dual linearly polarized and dual circularly polarized antenna array with muti-layers printed circuit board is proposed.Dual linearly polarizations are implemented by slots coupling and microstrip lines' side feeding, while the outputs of dual linearly polarizations and dual circularly polarizations are implemented by using a switch and a 90°bridge, respectively.By optimizing the parameters which affect antenna's performances, the antenna array is fabricated, with measured bandwidth of over 15% and antenna gain of over 17dB.The antenna unit manifests simply structure and low profile, which is an admirable candidate for the sub-array of large microstrip antenna arrays. |
