Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/066451
Kind Code:
A1
Abstract:
This patch antenna is configured from a ground conductor and a radiating element provided on a substrate. A dielectric member is positioned so as to overlap the radiating element when seen from a planar view. The dielectric member is positioned on the opposite side from the ground conductor when viewed from the radiating element. The dielectric member includes a lateral surface which is angled relative to a reference plane, when the normal direction of a radiating element is the height direction and a virtual plane orthogonal to the height direction is the reference plane. The dielectric member does not have a focal point for radio waves which are incident in parallel to the height direction.
