Design of a microstrip monopole wideband antenna with CPW feed has been discussed. The proposed antenna dimension is 30 mm x 45 mm x 1.6 mm. The substrate antenna uses FR-4 material with dielectric constant of 4.6. The simulation results suggests that the operating frequency ranges between 2.3 GHz and 3.4 GHz for VSWR of less than 1.5 and bandwidth greater than 2000 MHz for VSWR less than 2.
