In an antenna unit including a patch antenna, the antenna unit is provided with a non-feeding conductor wall so as to enclose the patch antenna. The conductor wall is, for example, made of metal. The conductor wall has a square main conductor plate apart from a bottom surface of the patch antenna, four side plates extending upward from four sides of the main conductor plate, and four trapezoidal tongue pieces extending inward from upper ends of the four side plates in parallel with the main conductor plate.
