WIPO Patent Application WO/2019/087610
Kind Code:
A1
Abstract:
[Problem] To implement an antenna having desired directivity easily at low cost. [Solution] A reflector comprising: a reflecting body which has a shape that, when a transmitter enters a predetermined region, allows an electric field strength when a receiver receives a radio wave transmitted from the transmitter to increase, and which is disposed so as to surround the receiver; and an opening which is formed on the side of the reflecting body that is closer to the predetermined region than the receiver. The opening of this reflector is rectangular, a first reflecting plate and a second reflecting plate that constitute the reflecting body may extend from a first side and a second side that face each other, among sides constituting the peripheral edge of the opening, so as to approach one other with increasing distance from the opening, and a third reflecting plate and a fourth reflecting plate that constitute the reflecting body may extend parallel to each other from a third side and a fourth side intersecting the first side and the second side, among said sides.
