Multiple beam wireless reception system has circular multiple beam printed circuit with beam switching mechanism, mounted on camera

摘要

The multibeam receiver mechanism has a set of printed circuit radiation receptors arranged to receive a wide azimuth sector. There is a mechanism (13,14,18) to switch between radiation patterns. There is also a control unit for regulating the switching circuit, for controlling the connection of a reception circuit to a following arrangement. The mechanism is held on a support (6) with cabling and attached to a camera (5).
