Abstract

A novel shorted CPW-fed slot antenna with wideband circular polarization characteristic is proposed in this letter. The proposed antenna consists of a bi-directional radiation slot antenna printed on a single substrate and a reflector for unidirectional radiation. A half circle slot and a slim slot are involved to optimize the axial ratio (AR) bandwidth and taper on the feeding line is utilised to further improve the impedance bandwidth. The measured results show that the antenna has the impedance bandwidth (S11 <; -10dB) of 12.6% and the AR bandwidth (AR <; 3dB) of 12.7%. The RHCP gain in the main radiation direction is 7.5 dBi..

cpw馈电宽带圆极化天线

本文提出了一种具有宽带圆极化特性的短路cpw馈电缝隙天线。所提出的天线包括印刷在单一基板上的双向辐射槽天线和用于单向辐射的反射器。利用半圆槽和细槽优化轴向比(AR)带宽，利用馈线上的锥度进一步提高阻抗带宽。测量结果表明，该天线具有阻抗带宽(S11 <;-10dB)为12.6%，AR带宽(AR <;3dB)为12.7%。主辐射方向的RHCP增益为7.5 dBi。
