Document Type and Number:
WIPO Patent Application WO/2022/239660
Kind Code:
A1
Abstract:
Provided are a reflector system, an active reflector, and an active reflector arrangement method that can efficiently eliminate a dead band region. The reflector system includes: a first active reflector that has a first reflecting surface at least partially provided in a boundary region located at a boundary portion between a line-of-sight region and a non-line-of-sight region formed by one or more shields for shielding radio waves transmitted by a transmitter and reflects the radio waves transmitted from the transmitter on the first reflecting surface for which the reflection angle can be changed; and a second active reflector that has a second reflecting surface provided in the non-line-of-sight region, or a second reflecting surface at least partially provided in the boundary region and reflects the radio waves transmitted from the transmitter or the radio waves reflected by the first active reflector, on the second reflecting surface for which the reflection angle can be changed.
