Analysis and design of broadband 90° sectoral microstrip antennas

Analysis and design of broadband 90° Sectoral microstrip antenna derived from 270° Sectoral patch is proposed. The formulation in resonant length at its fundamental mode and procedure to design 90° patch at different frequencies is presented. The proposed 90° patch yields higher bandwidth with better radiation pattern characteristics as compared to equivalent circular, 270° Sectoral, rectangular and their slot cut variations. © 2016 Wiley Periodicals, Inc.
