【摘要】 本文提出了一种宽带低剖面透射型线-圆极化转换器单元结构。单元结构简单易加工,圆、方片为主要结构组成。通过圆片中间开缝、方片中间挖孔、对角线对称放置短路柱等强弱耦合方式实现了宽频带匹配。仿真结果显示,3dB轴比相对带宽约84%,-2dB透射比相对带宽约81%,总剖面高度仅约0.076λ。故较好地实现了低剖面的宽频带线-圆极化的转换。更多还原

【Abstract】 In this paper, a broadband low-profile transmission type linear to circular polarization converter unit structure is proposed. The unit structure is simple and easy to process, with round and square pieces as the main structure. Broadband matching is achieved through strong and weak coupling methods such as slits in the middle of the wafer, hollowed out in the middle of the square,and diagonally symmetrical placement of short-circuit posts. The simulation results show that the relative bandwidth of 3 dB axial ratio is about 84%, the relative bandwidth of-2 dB transmittance is about 81%, and the total profile height is only about 0.076λ. Therefore, a low-profile broadband line-to-circular polarization conversion is better realized.更多还原
