Design of an H-shape cross slotted aperture-coupled microstrip patch antenna

Abstract

An H-shaped cross slotted aperture-coupled microstrip patch antenna with double-sided notches is presented. By proper choice of the notch dimensions, aperture size and foam material height, a wide band and high gain operation could be realized. The impedance bandwidth (based on a -10 dB return loss) of the designed antenna reaches about 12.5%. The maximum gain of the antenna is 9.35dBi, and the whole antenna is about 220mm*210mm*30mm.
