ANTENNA DEVICE

WIPO Patent Application WO/2021/161803

A1

This antenna device is disposed on a first surface, a second surface parallel to the first surface, and a third surface that connects the first surface and the second surface and is perpendicular to the first surface and the second surface, the antenna device comprising: a first antenna disposed on the first surface and the third surface; a second antenna disposed on the second surface; and a grounding line disposed on the first surface. The first antenna includes: a first feeding point disposed on the first surface; a first conductive element disposed on the first surface and extending from the first feeding point to the third surface; and a second conductive element disposed on the third surface and extending from an end portion of the first element to the first surface. The second antenna includes: a second feeding point disposed to be spaced apart from the first feeding point in a direction parallel to the first surface and the second surface; and a conductive antenna element extending from the second feeding point. The grounding line includes: a grounded point that is grounded; and a conductive grounding element that is connected to the grounded point, includes a portion extending along the first antenna, and is capacitively coupled to the first antenna.
