Proximity Fed Broadband 1200 Sectoral Microstrip Antenna

Novel configuration of 1200 Sectoral Microstrip antenna is proposed. Compared with equivalent circular patch, 1200 Sectoral patch has higher resonance frequency for the fundamental mode and it gives bandwidth of 1200 MHz (~59%). Resonant length formulation at fundamental mode in 1200 Sectoral patch is proposed. Using the same, design of 1200 Sectoral patch at resonance frequency of 1000 MHz is presented which yields more than 575 MHz (~ 50%) of bandwidth. This bandwidth is more than that obtained in circular patch operating in the same frequency range. Proposed 1200 Sectoral patch gives broadside radiation pattern with peak co-polar gain of more than 9 dBi.
