Abstract

This paper presents a wideband circular polarization antenna with tuning rectangular slot fed by coplanar waveguide (CPW). The proposed antenna has been designed to enhance widely the impedance bandwidth. Circular polarization is achieved by the slots around two opposite corners of the square slot. A small tuning stub is placed at the end of strip on CPW to obtain a good impedance matching. The proposed antenna attains an over-lapped bandwidth (axial ratio ≤ 3 dB and return loss ≤ 10 dB) of 17.39% (2.31–2.75 GHz) in measurement.

一种带调谐矩形槽的宽带圆极化天线

本文提出了一种共面波导馈电带调谐矩形槽的宽带圆极化天线。所提出的天线被设计成可以广泛地提高阻抗带宽。圆偏振是通过在方形槽的两个相对角周围的槽来实现的。在CPW的条带末端放置一个小的调谐根，以获得良好的阻抗匹配。经测量，该天线的重叠带宽(轴比≤3db，回波损耗≤10db)为17.39% (2.31-2.75 GHz)。
