Abstract :
Design of simple circularly polarized microstrip antenna(CPMSA) is proposed. Circular polarization has been obtained by truncating the diagonal corners of the MSA. Bandwidth is enhanced by increasing the substrate height. Inserted slots further enhanced the AR BW.Center frequency of CPMSA is 2.438GHz. VSWR bandwidth of 120 MHz & axial ratio bandwidth of 71.64MHz which is approximately 2.5 times greater than obtained in[11], Gain of 7.5dBi and very good radiation pattern in the broadside direction is achieved. Which can be used for WLAN application. MSA is simulated by CAD FEKO(6.1) software using Method of Moment (MoM) technique[7]. Simulated results are in good agreement with the measured results.
