Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/104754
Kind Code:
A1
Abstract:
An antenna device (1) is provided with a dielectric substrate (2), a ground plate (3) arranged on a first surface of the dielectric substrate, an antenna part (4) arranged on a second surface of the dielectric substrate, and a reflecting part (5). The reflecting part has a plurality of conductor patches arranged around the antenna part, said patches acting as a reflecting plate. The plurality of conductor patches form a plurality of blocks aligned along a preset block array direction. The plurality of blocks are configured so that the phases of the reflected waves at the operating frequency for each block are different, and for each of adjacent blocks, the phase difference of the reflected waves between the adjacent blocks differs non-uniformly.
