A coplanar waveguide (CPW) fed circularly polarized monopole antenna is presented. The monopole antenna is placed inside a hexagonal shaped slot which is acting as a ground plane. A pair of L-shaped stubs are placed diagonally inside the slot. In order to enhance the impedance bandwidth a spiral discontinuity is created in the grounded ring, near to the edge of the L-stub. The measured result shows that the proposed antenna exhibit a 3-dB axial ratio bandwidth of 480 MHz (4.55 GHz – 5.03 GHz) and impedance bandwidth (|S11| < −10dB) of 4.17 GHz (2.97 GHz – 7.14 GHz).
