摘要： An exemplary wireless communication apparatus includes a first communication circuit, a second communication circuit, an antenna, and a combiner. The first communication circuit is arranged to process signals according to a first wireless communication protocol working at a first frequency band. The second communication circuit is arranged to process signals according to a second wireless communication protocol working at a first frequency band, wherein the second wireless communication protocol is different from the first wireless communication protocol. The antenna is shared between the first communication circuit and the second communication circuit. The combiner has a first port coupled to the first communication circuit, a second port coupled to the second communication circuit, and a third port coupled to the antenna. In addition, the combiner provides a first signal path between the third port and the first port and a second signal path between the third port and the second port.
