Abstract

In this paper, a simple broadband multipolarized traveling-wave series-fed antenna array is proposed. The radiation unit cells are multiple squares. The square unit cell will change between circular polarized (CP) and linear polarized (LP) through a reasonable feeding mode. By adjusting the equivalent length of the unit cell, the Q value of the antenna can be reduced, resulting in the increase of the bandwidth of the array. The array consists of seven-unit cells and dual-port feeding. The unit cells which are connected by a microstrip line are arranged in a circular array. A reasonable layout of unit cells can achieve good port isolation of the array. The polarization performance of the array antenna is the same as that of the unit cell. The antenna is fabricated and measured. The measured results are consistent with the simulated results.

基于贴片的多极化行波串馈天线阵列

本文提出了一种简单的宽带多极化行波串联馈电天线阵列。辐射单元格是多个正方形。通过合理的馈电方式，方形晶胞将在圆极化(CP)和线极化(LP)之间转换。通过调整单元格的等效长度，可以降低天线的Q值，从而增加阵列的带宽。该阵列由七个单元单元和双端口馈电组成。通过微带线连接的单元格排列成圆形阵列。合理的单元格布局可以实现阵列良好的端口隔离。阵列天线的极化性能与单元天线的极化性能相同。制作并测量了天线。实测结果与模拟结果吻合较好。
