Summary:
This paper describes the shape of an aperture that yields a significantly improved degree of coupling for aperture-coupled patch antennas. A bow-tie shaped aperture consists of a slot with a narrow center and the width steadily increases toward each end. Simulation data show an increase of up to 44% in the resonant frequency bandwidth of an antenna using the bow-tie shaped aperture, compared to that for the same antenna with a rectangular slot or dog-bone shaped slot. The field distributions of the three slot types are also simulated and compared.
