Progress In Electromagnetics Research Letters, Vol. 41, 77-86, 2013
Abstract
A coplanar waveguide-fed slot antenna with wideband circular polarization characteristic is presented. The proposed antenna consists of an irregular slot with a stair-shaped edge and an L-shaped feed line. The stair-shaped edge can improve the circular polarization of the antenna. The simulated and measured results show that the antenna has an impedance bandwidth (VSWR < 2) about 1040 MHz (42%@2.47 GHz) and an axial ratio (AR) bandwidth (AR < 3 dB) about 640 MHz (25.8%@2.48 GHz) for 2.45 GHz RFID applications. The RHCP gain in the main radiation direction varies between 2.3 dBi and 3.8 dBi.
