两种应用于宽带阵列天线的阵列单元

Two Kinds of Array Elements Applied to Wide-band Array Antenna

介绍了两种应用于宽带相控阵中的阵列单元,分析了每种天线的性能和优点,对天线单元进行了充分的设计、仿真和优化,仿真结果与实测结果基本一致。组成9×9的阵列,并对阵列中单元进行测量,对测量数据进行处理。结果显示出良好的宽带特性,具有较低的互耦等优点,可应用于三坐标雷达系统。

This paper introduces two kinds of array elements applied to the wide-band phased array, analyzes the performances and merits of each antenna, designs, simulates and optimizes the antenna units fully,the simulative result is basically consistent with the practical measuring result. The array with 9× 9 elements was built up and the array units are tested,the testing data are performed, the result shows the array has the characteristics of perfect wide-band and low mutual coupling, etc. ,which can be applied to the three-dimensional radar system.
