Phase shifter

A phase shifter, comprising:

• a base;
• a circuit substrate disposed on the base, comprising a main feeder circuit and at least one sub-feeder circuit, the main feeder circuit comprising a main input circuit section, the at least one sub-feeder circuit being disposed on one side of the main feeder circuit, the at least one sub-feeder circuit comprising two output circuit sections and an arc circuit section;
• the arc circuit section being disposed between the two output circuit sections;
• a phase-shifting member rotatably connected with the circuit substrate, comprising a coupling band, one end of the coupling band corresponding to and being coupled to the main input circuit section while the other end corresponding to and being coupled to the arc circuit section;
• and
• a plurality of first output cables being respectively connected to one end of the corresponding output circuit section away from the arc circuit section, each of the phase values output by the plurality of first output cables is different from other phase values output by the plurality of first output cables;
• wherein the plurality of first output cables are in the same length;
• the length of each of the output circuit sections is different from the length of other output circuit sections;
• the length of each of the output circuit sections is determined by the phase value output by the first output cable connected with the output circuit section.
