Abstract :
A novel broad-band microstrip antenna is presented. The printed configuration consists of a shorted circular patch and a concentric parasitic annular ring. Compared to a conventional microstrip patch, this ensemble is smaller in size with enhanced impedance bandwidth. Both experimental and theoretical impedance behavior and radiation characteristics of the modified patch are considered. Very good agreement between the experiment and the theory was achieved
