Analysis and design of small size short circuited microstrip T-shaped antenna

A small size short-circuited microstrip T-shaped antenna is presented. The antenna is analyzed by placing electric and magnetic walls at the plane of symmetry. Design equations and curves are introduced. The proposed approach has been validated through the design and implementation of an antenna at 850 MHz. Significant size reduction has been achieved. The IE3D soft ware is used to simulate the designed antenna. The experimental results agree well with the theoretical prediction.
