The broadband microstrip antenna is realized by fabricating the patch on lower dielectric constant thicker substrate followed by using proximity feeding technique. The proximity feeding technique realizes broader bandwidth for substrate thickness more than 0. 06?0. In this paper, proximity fed ETMSA is discussed. By placing the shorting plate along the zero field line at the fundamental mode of the patch, proximity fed compact shorted 600 sectoral MSA is proposed. It gives bandwidth of nearly 550 MHz at center frequency of nearly 1000 MHz. It shows radiation pattern with maximum in the end-fire direction and gain of more than 5 dBi over the bandwidth. Further by using symmetry of 600 sectoral patch, a compact half shorted 600 sectoral microstrip antenna is proposed. It gives simulated and measured bandwidth of 220 MHz with radiation pattern having maximum in end-fire direction and gain of more than 6 dBi over the entire VSWR BW.
