Abstract: A communication apparatus includes a phase shifter, an input port, and an output port. The phase shifter includes a first structure that includes a first phase difference coupler, a second phase difference coupler, a first, second, third, fourth, a fifth and a sixth phase shifter, a cross coupler, a first combiner, and a second combiner. The first phase difference coupler is coupled to the third and fourth phase shifter, and is further coupled to the cross coupler and the first combiner. The second phase difference coupler is coupled to the fifth and sixth phase shifter, and is further coupled to the second phase shifter and the second combiner. A second output port of the first phase difference coupler is coupled to a first input port of the cross coupler. A first output port of the second phase difference coupler is coupled to an input port of the second phase shifter.
