WIPO Patent Application WO/2024/070003
Kind Code:
A1
Abstract:
Provided is an antenna device with which a high antenna gain and a broad directional angle range can be realized. The antenna device comprises: a plurality of antenna units, each having disposed therein a plurality of antenna elements at intervals of at least 0.5 times the wavelength of a radio wave to be received; and a connection circuit having a plurality of connection paths that are connected at different path lengths to the plurality of antenna units so that the angular directions of directional beams of the plurality of antenna units are different from each other. The plurality of antenna elements may be disposed at intervals of at least one time the wavelength of the radio wave to be received so that the antenna units have a plurality of directional beams. The path lengths of the plurality of connection paths may be set so that the angular directions of the plurality of directional beams are different between the plurality of antenna units.
