Abstract
The present invention discloses a phase shift system that is used for changing phases of signals transmitted to at least two radiation elements, comprising at least two phase shifters providing signals to the radiation elements, the phase shifter having a phase shift part used for moving so as to change phases of signals passing through the phase shifter. The system further comprises a phase shift drive device that is connected to the phase shift part of each phase shifter for synchronous linkage of all the phase shift parts, such that the phase shift parts move at different velocities to form a differential continuous phase distribution among the signals of the radiation elements. Through the above mode, the present invention can form a phase shift system with a relatively high number of ports by combining a plurality of phase shifters, and all the ports can form the differential continuous phase distribution.
