Abstract :
This paper describes the 2-array microstrip patch antenna using an aperture-coupled waveguide at 24 GHz. The antenna consists of a waveguide feed and two patches that are excited by the endwall coupler. This antenna has the gain of 12 dBi and the bandwidth of 2.4 GHz. Half power beamwidth is 30 degree on the E-plane and 68 degree on the H-plane.
