Design of a Reconfigurable, Multi-frequency & Circularly Polarized Microstrip Patch Antenna
In this microstrip antenna design multi frequencies are used. Here working frequencies are 1.9GHz and 2.0GHz. Rectangular patch shape technique is used for designing this microstrip antenna. In the authors' model electric field lines, conductance and input resistance have obtained by transmission line model whereas charge distribution, directivity and gains have brought by cavity model of rectangular patch. Correct feeds are applied at various positions and after comparing all the results the best of all will increase the efficiency and gain of microstrip patch antenna by 30-35%.
