Title:
ANTENNA DEVICE AND RADAR SYSTEM
Document Type and Number:
Japanese Patent JP2020080464
Kind Code:
A
Abstract:
To improve the resolution of an antenna with a directivity in a two-dimensional direction and the characteristics of a beam sweep.SOLUTION: A plurality of antenna elements are arranged in a two-dimensional flat pattern. A first power supply line and a second power supply line are for supplying power from a first direction and a second direction, which are different directions, to a plurality of antenna elements. Switching the direction of power supply changes the directivity. The first and second power supply lines may each have a plurality of power source lines. Supplying power to a plurality of power supply lines at different phases changes the directivity.SELECTED DRAWING: Figure 1
