An embodiment of the present invention provides a wireless terminal, including a PCB and an antenna system, where the antenna system includes a positioning antenna for receiving a positioning carrier signal from a satellite, and a wave director is disposed in a radiation area of the positioning antenna, and is used to couple energy from the positioning antenna to the wave director and radiate the energy to space. In this embodiment of the present invention, a wave director is disposed in a radiation area of a positioning antenna, and a space low-resistance path for a carrier signal (namely 1575.42MHz radio frequency signal) from a satellite is formed, so that it can be implemented that energy of the positioning antenna is coupled to the wave director, and the coupled energy is radiated by the wave director to space to form a coupling radiation field, thereby improving radiation efficiency of an antenna system and further implementing directional guidance for radiation at the same time. |
