摘要
本文设计了一款宽带高增益定向±45°双极化天线。首先,采用折合偶极子互相垂直放置作为天线的辐射单元,实现了±45°双极化辐射。其次,将四个折合偶极子方环形排列,两个相对的天线单元辐射相同极化的电磁波,使得天线在频带内增益高。然后,通过在折合偶极子的下方放置一块带有翻边的U形反射板提高了方向图的稳定性。最后,根据折合偶极子的排布方式,设计了天线的馈电网络。根据仿真结果,加工了天线样机并进行了测试。仿真和实测结果表明该天线在2.5-3.8GHz频带内反射系数小于-10d B,天线的端口隔离度在工作频带内大于32d B。整个频带内天线增益高于9.2d Bi,天线的水平面3d B波束宽度在67°±2°之间,且轴向交叉极化比大于23dB。
A broadband plus/minus 45 degree dual-polarized directional antenna with high-gains is proposed in this paper. The antenna is composed of four folded dipoles, a U-shaped ground plane and a broadband feeding network. Four folded dipoles lead to high antenna gains. To get stable radiation patterns, a U-shaped metal reflector is placed under the antenna. The antenna is manufactured according to simulated one. The dual-polarized antenna obtains a bandwidth of 41.3% from 2.5 to 3.8 GHz, and the port isolations are better than 32 d B in the whole frequency band. The antenna gains are higher than 9.2 d Bi, and stable radiation patterns in the horizontal plane with 3 d B beamwidths 67° ± 2° are also obtained. The cross-polarization ratios are larger than 23 d B. Simulated and measured results show good agreement across the entire frequency band.
