摘要
本文提出了一种具备高口径效率与可重构散射特性的圆极化天线阵列设计方法.首先，基于p-i-n二极管设计了一种可重构天线单元，在保持圆极化辐射特性稳定的前提下，实现了相位差180°的两种散射状态切换.其次，通过创新性地采用馈电结构重叠设计，显著减少了单元中二极管的使用数量，从而提升了辐射性能.最终，基于该单元构建了2 × 8圆极化相控阵，其在9.4 GHz工作频率下实现了14.6 dBic的增益和86.5%的口径效率.此外，该阵列的辐射波束可在±45°范围内扫描，同时其散射波束能在±32°范围内有效调控，且不影响圆极化辐射特性的稳定.实测与仿真结果的高度一致性验证了设计方法的有效性.
Abstract
A design method for circularly polarized antenna arrays featuring high aperture efficiency and reconfigurable scattering characteristics is proposed. Firstly
a reconfigurable antenna element is constructed using p-i-n diodes
which achieves two scattering states with a phase difference of 180° while maintaining stable circularly polarized radiation characteristics. Secondly
by innovatively adopting an overlapping feeding structure design
the number of diodes used in the antenna element is significantly reduced
effectively improving the radiation performance. Finally
a 2 × 8 circularly polarized phased array is constructed based on this element
achieving a gain of 14.6 dBic and an aperture efficiency of 86.5% at 9.4 GHz. Additionally
the radiation beam of the array can be scanned within a range of ±45°
and its scattering beam can be effectively adjusted within a range of ±32° without compromising the stability of its circularly polarized radiation characteristics. The high consistency between the measured and simulation results verifies the effectiveness of the proposed design method.
