In this paper the bandwidth of a conventional rectangular microstrip antenna has been enhanced by locating capacitively excited λm/4 short circuit parasitic elements at its radiating and non-radiating edges along with the circular polarization and loading the parasitic elements with the rectangular slots. An impedance bandwidth of 1.53513 GHz to 1.843438 GHz (308.3MHz). It has three resonances at 1.56GHz, 1.67GHz and 1.8 GHz. The result are simulated by MOM based IE3D software.
