Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/024391
Kind Code:
A1
Abstract:
An antenna device (100, 100a) is provided with a mirror (120, 120a) comprising: a first reflector (130, 130a) having a first grid reflection surface (131, 131a) that reflects radio waves in one of two regions resulting from division by a first plane and that is constituted by a grid consisting of a plurality of stripe members extending in a direction orthogonal to the first plane; a second reflector (140, 140a) having a second grid reflection surface (141, 141a) that reflects radio waves in the other region and that is constituted by a grid consisting of a plurality of stripe members extending in the direction orthogonal to the first plane; a third reflector (150, 150a) having a third grid reflection surface (151, 151a) that reflects radio waves in one of two regions resulting from a division by a second plane orthogonal to the first plane and that is constituted by a grid consisting of a plurality of stripe members extending in a direction orthogonal to the second plane; and a fourth reflector (160, 160a) that reflects radio waves in the other region.
