    摘要: A multiple-feed antenna system includes a primary reflector that directs signals along a primary RF signal path and a movable subreflector assembly. When the subreflector assembly is in a first position, a first subreflector element of the subreflector assembly redirects signals traveling along the primary RF signal path to a first RF signal path and a second subreflector element of the subreflector assembly does not intersect the primary RF signal path. When the subreflector assembly is in a second position, the second subreflector element redirects signals traveling along the primary RF signal path to a second RF signal path and the first subreflector element does not intersect the primary RF signal path. The antenna system includes a first feed of the antenna system intersects the first RF signal path, a second feed that intersects the second RF signal path, and an actuator that moves the subreflector assembly.

    摘要: A mounting unit (210) securely mounts a radio wave reflection device (200) on a stable installation place such as a pole (20). A reflector unit (300) holds two reflectors (350, 360) at a tilt angle of 45°, allowing the two reflectors (350, 360) to be coaxial and rotatable independently of each other. A joint unit (220) connects the reflector unit (300) and the mounting unit (210). The joint unit (220) has rotational freedom along two axes (AZ axis and EL axis) orthogonal to each other. A radio wave reflecting device that relays, by reflection, radio communications between a first antenna device and a second antenna device distant from each other is thereby provided.
