Abstract: A wireless terminal is disclosed. The wireless terminal includes a first antenna, a second antenna, a printed circuit board, a bracket, and a resonator, where the first antenna is located at one side of the printed circuit board, the second antenna is located at another side of the printed circuit board, the printed circuit board functions as a metal ground of the first antenna and the second antenna, the resonator is located on the bracket, a ground point of the resonator is located on the printed circuit board, and a clearance exists between the resonator and the printed circuit board. Not only does the wireless terminal improve isolation between multiple antennas, but also the resonator can better radiate energy of the antennas because a clearance exists between the resonator and the PCB.
