Abstract

In this paper, we propose a method to decrease back-lobe radiation of the small Circular Polarized (CP) antenna. The proposed CP antenna is composed of four antenna elements arranged in a rotational symmetry at 90 degrees on the ground, which are excited with the same amplitude and 90 degrees phase difference. Each antenna element is formed by a spiral antenna branched from the near the middle of an inverted-L antenna. From the result of simulation, backward radiation of the proposed CP antenna can be decreased by 13 dB due to the addition of the spiral elements.

带螺旋元件的低后瓣小型化圆极化天线

本文提出了一种减小小型圆极化(CP)天线后瓣辐射的方法。所提出的CP天线由四个天线单元组成，四个天线单元在地面上以90度旋转对称排列，以相同的振幅和90度相位差激励。每个天线单元由从倒l型天线的近中部分支的螺旋天线组成。仿真结果表明，由于螺旋元件的加入，所提出的CP天线的反向辐射可降低13 dB。
