Abstract: A patch antenna is constituted by a radiation element disposed on a substrate and a ground conductor disposed in the substrate. A dielectric member is disposed to cover the radiation element and a body of a resin material is disposed to cover the dielectric material as viewed from above. The dielectric member is disposed on a side opposite a side on which the ground conductor is disposed as viewed from the radiation element. When a direction of a normal line to the radiation element is assumed as a height direction, a line which links centroids of horizontal sectional surfaces of the dielectric member in the height direction leans with respect to the direction of the normal line to the radiation element.

Abstract: A feed element for feeding power is disposed on a substrate. A first parasitic element is disposed at a position different from a position of the feed element as viewed from above and is electromagnetically coupled with the feed element. A dielectric member is disposed at a position at which the dielectric member at least partially covers the feed element and the first parasitic element as viewed from above. A conductive pattern is disposed on a surface of the dielectric member which faces the feed element at a position at which the conductive pattern matches the first parasitic element as viewed from above. The dielectric member is supported by the substrate as a result of the conductive pattern being electrically connected to the first parasitic element.

A dielectric member is disposed to at least partially cover the radiation element as viewed from above. The dielectric member is disposed on a side opposite a side on which the ground conductor is disposed as viewed from the radiation element. When a direction of a normal line to the radiation element is assumed as a height direction and when an imaginary plane perpendicular to the height direction is assumed as a reference plane, the dielectric member has a side surface which tilts with respect to the reference plane. The dielectric member has no focal point for a radio wave entering the dielectric member in parallel with the height direction.
