WIPO Patent Application WO/2023/127765
Kind Code:
A1
Abstract:
[Problem] To facilitate the achievement of a desired antenna gain with a structure in which a connector having a metal member is used to connect a transmission line to an antenna. [Solution] The present invention comprises: an antenna 50 that has a dielectric substrate 52, a radiation plate 56, and a ground conductor plate 54; a connector 70 that is provided to the surface of the ground conductor plate on the reverse side from the radiation plate side, includes a metal member, is fixed to the antenna, and supports a transmission line; and a cover member 95 that faces the surface of the ground conductor plate on the reverse side from the radiation plate side, and is formed from an electrically-grounded conductor. In a front view of the antenna, the position of a power-feeding point on the radiation plate, which is a location where power is supplied from the transmission line, differs from the center of gravity position of the radiation plate, and when the antenna, the connector, and the cover member are viewed along a direction orthogonal to a first straight line connecting the center of gravity and the power-feeding point and to the thickness direction of the dielectric substrate, the antenna and the cover member cover the periphery of the connector.
