The embodiment of this application discloses a relay device. The relay consists of at least two interconnected beam selection systems, each consisting of an aperture antenna, multiple feeds, a radio-to-DC converter and a beam selection control device; each of the at least two beam selection systems corresponds to a different beam scanning range; and the radio-to-DC converter couples the radio-frequency signals received by the feeder to control the beam selection. Coupled radio frequency signals are converted to direct current signals for beam selection control devices, which are used to select working feeds based on multiple direct current signals. Through the embodiment of this application, the relay device can realize beam alignment according to the received radio frequency signal and provide the power needed for the operation of the relay device, thus greatly reducing the deployment requirements.
