Abstract: A coupler for use in a wireless communication device includes a signal input end, a signal output end, a coupling end, an isolation end, a main signal hole, and a first coupling hole disposed on a PCB. A first end of the main signal hole is coupled to the signal input end. A second end of the main signal hole is coupled to the signal output end. A first end of the first coupling hole is coupled to the coupling end. A second end of the first coupling hole is coupled to the isolation end. In a thickness direction of the PCB, the first end of the first coupling hole and the first end of the main signal hole are close to a first side of the PCB, and the second end of the first coupling hole and the second end of the main signal hole are close to a second side of the PCB.
