Phase shift system

The present invention discloses a phase-shift system, a phase signal for at least two radiating elements to change the output, comprising at least two phase shifters provides a signal to the radiating element, for moving the phase shifter has to vary the flow through the phase shifting means a phase signal the phase shifter. The system further comprises: a phase shift drive means, phase shifting means respectively each phase shifter is connected to the phase shifting means is moved simultaneously, so that the phase shifting means to move at different rates, signals to the radiating element forming a differential between the continuous phase distribution. By the above-described embodiment, the present invention can utilize a combination of a plurality of phase shifters number of ports formed more phase shifting system, and each port may be formed in a continuous differential phase distribution.
