Abstract :
Cavity backing of the conventional rectangular microstrip antenna is being proposed. The proposed antennas have been simulated. An input impedance of 71 % for VSWR /spl les/ 2.00 has been obtained from the proposed antenna. Results obtained for the cavity backed and without cavity backed antenna has been compared. It has been found that by cavity backing the conventional antenna bandwidth increases many times.
