PURPOSE: A dual patch antenna is provided to offer a broadband antenna function by arranging two power feed patches on a same plane with a radiation patch without laminating a plurality of dielectric layers. CONSTITUTION: A radiation patch(20) is combined with the upper surface of a dielectric layer. A first power feed patch(30) is combined with the upper surface of the dielectric layer. The first power feed patch is separately formed with the radiation patch. A second power feed patch(40) is combined with the upper surface of the dielectric layer. The second power feed patch is separately formed with the radiation patch. An earth patch is combined with the bottom surface of the dielectric layer. The area of the radiation patch is bigger than the area of the first power feed patch and the area of the second power feed patch.
