Title:
ANTENNA REFLECTOR AND WIRELESS COMMUNICATION DEVICE COVER
Document Type and Number:
WIPO Patent Application WO/2023/203752
Kind Code:
A1
Abstract:
An antenna device provided by the present invention is an antenna reflector for reflecting radio waves emitted by multiple patch antennas arranged side by side. The antenna reflector comprises: a first conductor plate, which is arranged so as to overlap with the multiple patch antennas when viewed in a direction in which the radio waves are emitted, and is also arranged obliquely to the emission direction in which the radio waves are emitted by the patch antennas when viewed in a vertical direction orthogonal to the arrangement direction of the multiple patch antennas and the emission direction; and a second conductor plate which is arranged to face one surface of the first conductor plate. The one surface of the first conductor plate is formed in a parabolic curved surface concave toward a substrate in a cross-section thereof when viewed in a normal direction of the substrate, the surface of the second conductor plate facing the first conductor plate side is formed flat or in a parabolic curved surface convex toward the first conductor plate, and a substrate-side end part of the first conductor plate and a substrate-side end part of the second conductor plate are arranged so as to sandwich the multiple patch antennas when viewed in a vertical direction.
