ABSTRACT:
A patch antenna with a directivity includes: a dielectric substrate to which at least one through hole is provided; a first ground electrode at least partially covering a back surface of the dielectric substrate; an antenna electrode partially covering an area of a front surface of the dielectric substrate, the area positionally corresponding to the first ground electrode; a second ground electrode provided within the area in a vicinity of the antenna electrode, the second ground electrode having the through hole underneath; and a conductive material provided in the through hole so as to electrically connect the first ground electrode and the second ground electrode.
