Abstract
A planar differential aperture antenna that has a high gain and wide bandwidth at a millimeter wave band is provided. The differential aperture antenna has a cavity within it that has a height of roughly a quarter of a wavelength of the desired transmission band. The cavity is H-shaped, and has a cross shaped patch within the cavity that is fed differentially by two grounded coplanar waveguides. Two ends of the patch extend towards the ports on either side of the differential aperture antenna, and the other two ends of the patch extend into the cavity lobes, perpendicular with respect to the ports.
