| Zusammenfassung: | 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 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. |
