Multipath switching system having adjustable phase shift array
A multipath switching system comprising of an adjustable phase shift array includes, an adjustable phase shift array module and a control module. The adjustable phase shift array module receives a radio-frequency (RF) signal, and includes at least one RF switch, at least one coupler and at least one phase shifter. The at least one RF switch, the at least one coupler and the at least one phase shifter form a number of transmission paths. The transmission paths respectively produce the processed transmission RF signals corresponding to different phase shifts to an antenna array. The control module controls the at least one RF switch and the at least one phase shifter of the adjustable phase shift array module, so that the antenna array radiates a wireless signal whose direction is corresponding to a predetermined angle in space polar coordinates.
