Title:
ANTENNA DEVICE AND RADAR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/100365
Kind Code:
A1
Abstract:
The present invention makes it possible to improve beam sweep characteristics and resolution in a two-dimensional direction in an antenna provided with directivity. A plurality of antenna elements is disposed in a two-dimensional plane shape. First and second power supply wires are wires for supplying power to the plurality of antenna elements from a first direction and a second direction, which differ from each other. Switching the power supply direction changes the directivity. Each of the first and the second power supply wires may be provided with a plurality of power supply lines. Supplying power to the plurality of power supply lines at mutually differing phases changes the directivity.
