This paper presents a CPW fed dual-band dual-sense circularly polarized (CP) square slot antenna. The proposed antenna consists of a rectangular radiator with two unequal rectangular strips, connected by a CPW feed line and an asymmetric T-shaped stub is placed in the right side of the slotted ground plane with the orthogonal direction of the feed line. The proposed antenna obtained two CP bandwidth from 3.72GHz-4.14GHz (LHCP) and 5.3GHz-6.06GHz (RHCP) with axial ratio (AR) value less than 3dB and both the CP band are overlapped by impedance bandwidth of the antenna, ranging from 3.7GHz-7.15GHz. Design procedures of the antenna are discussed in details for further understanding of the antenna design. Total size of the proposed antenna is 50×50×1.58 mm3. The antenna is fabricated on FR4-epoxy substrate and measured results are discussed in details.
