Document Type and Number:
Japanese Patent JP2020077988
Kind Code:
A
Abstract:
To provide a technique for expanding a communicable angle range without increasing a scale of a high-frequency circuit for processing transmission and reception signals of an antenna.SOLUTION: A base 3 has one installation surface 3a formed in a planar shape. An antenna unit 6 is formed on the installation surface 3a and has a plurality of directional antennas configured to have a peak of directivity in a direction intersecting with the installation surface 3a. A reflection unit 4 has a plurality of reflecting surfaces for tilting directions indicated by peaks of the directional antennas to be oriented in mutually different directions in a plane at least along the installation surface 3a by reflecting electromagnetic waves transmitted and received by the antenna unit 6.SELECTED DRAWING: Figure 1
