摘要

利用元件的非均匀布局和随机旋转，设计了一种具有低旁瓣电平的平面广角扫描阵列。首先设计了微带单极天线单元，获得了宽波束和圆极化。此外，还对阵列元件的位置和旋转角度进行了优化，以实现低SLL和提高轴比(AR)性能。制作并测量了该阵列。实验结果表明，所设计的相控阵在两个正交平面上支持±56°的扫描，增益波动为4.3 dB，与仿真结果一致。

A Planar Circular Polarization Wide-Angle Scanning Phased Array Based on Nonuniform Layout and Element Random Rotation

In this paper, a Planar wide-angle scanning array is designed with low sidelobe level (SLL) by the nonuniform layout and the random rotation of elements. Initially, a microstrip-monopole antenna unit is designed and the wide beam and circular polarization are obtained. Besides that, the positions and rotation angle of array element are optimized to realize low SLL and improve the axis ratio (AR) performance. The array is fabricated and measured. The experimental results indicate that the designed phased array support a scan up to ±56° in both orthogonal planes with the gain fluctuation of 4.3 dB, which are identical to the simulation results.
