团队有关一种基于机械重构单元方向图的高效率宽角扫描机电混合相控阵天线的成果在IEEE AWPL期刊上发表

发布时间:2023-12-26   点击次数:

论文名称High-Efficiency Wide-Angle Scanning Mechanoelectrical Hybrid Phased Array Antenna With Mechanically Reconfigurable Element Pattern针对现有宽角扫描相控阵大大角度扫描效率低、扫描范围有限等问题。本文提出了一种具有机械可重构单元方向图的高效宽角扫描机电混合相控阵天线。所提出的阵列由若干可以机械旋转的线阵面板组成。与传统的机电混合扫描天线阵在方位角平面上连续旋转不同,所提出天线在俯仰面上旋转,且只有三种固定旋转状态从而能够实现快速的波束切换能力。本文研究了最优单元方向图的3dB波束宽度和最佳面板旋转角度,从而获得天线在旋转平面内的最佳扫描范围和增益性能。以等效磁偶极子贴片天线为原型,设计并制作了一个8 × 8阵列,并对其单元的3dB波束宽度进行了合理设计,使其满足最优值。仿真和实验结果表明,该设计天线主波束可实现yoz- 67°~ 67°xoz- 75°~ 75°范围内扫描,其3db波束覆盖范围分别为±82°±90°。此外,该阵列的峰值效率可达75%。。工作主要完成人:林宏声,程钰间。

Abstract— In this letter, a high-efficiency wide-angle scanning mechanoelectrical hybrid phased array antenna with mechanically reconfigurable element pattern is proposed. The proposed array is composed of several linear array panels, which can be mechanically rotated. In contrast to conventional hybrid scanning arrays, it rotates in the elevation plane with only three fixed states enabling quick beam switching capabilities, rather than constantly rotating in the azimuth plane. The optimal element's half-power beamwidth (HPBW) and panel rotation angle are examined in this letter to produce the best scanning range and gain performance in the rotation plane for the array. As a prototype, an 8 × 8 array formed by an equivalent magnetic dipole patch antenna, whose HPBW is properly designed to satisfy the optimal value, is configured and fabricated. Both simulated and experimental results show that the proposed array can scan its main beam from −67° to 67° in the yoz -plane, −75° to 75° in the xoz -plane, and its 3 dB beam coverage reaches ±82°, ±90° in the two planes. Additionally, the peak efficiency of the array can reach 75%.
