摘要：
An antenna apparatus includes a dielectric substrate, a radiation element buried in the dielectric substrate, and a feeding lead connected to the radiation element and extending outward from the dielectric substrate. The dielectric substrate is covered with a conductor cover except at an exposed portion left on an upper surface thereof. The conductor cover comprises a side wall portion extending in a thickness direction of the radiation element and covering all side surfaces of the dielectric substrate, and a hood portion extending from an upper edge of the side wall portion and covering a part of the upper surface of the dielectric substrate. The hood portion has a trapezoidal or a rectangular shape.
