Abstract

This paper presents a new Circularly polarized square slot antenna (CPSSA) with a coplanar wave guide (CPW) feed. The proposed antenna contains inverted-L Grounded strips around the corners. Circular polarization mechanism is related with the L-shaped strips, vertical staircase shaped feed line extension and the thin tuning strip. Compared to most of the previously reported CPSSA structures, the axial ratio bandwidth is increased and also the size of the antenna becomes smaller. The presented compact antenna has 40 × 40 × 0.8 mm 3 dimensions. The operation bandwidth for VSWR < 2 is from 3.45 to 8.59 GHz and exhibits a 53.67% (4.73-8.20GHz) 3dB Axial ratio bandwidth. Throughout this letter, the improvement process of the axial ratio (AR) and S11 properties are discussed in detail.
