Embodiment 1
[0024] Embodiment one, such as figure 1 As shown, the antenna device of this embodiment includes V-shaped antenna 12 , first matching circuit 11 , shorting device 13 and other main components. Wherein, the V-shaped antenna 12 is used as a directional antenna, which can form a directional radiation field in a specific direction, so as to improve the wireless communication performance of the antenna device in a specific direction. The V-shaped antenna 12 of this embodiment is preferably placed externally in the intelligent communication terminal, so as to facilitate the adjustment of the radiation direction of the V-shaped antenna 12 . Specifically, the V-shaped antenna 12 includes two radiating bodies, which are respectively defined as a first radiating branch 121 and a second radiating branch 122 . The first radiating branch 121 and the second radiating branch 122 are arranged outside the casing of the intelligent communication terminal, the first ends A are butted to form a ...
Embodiment 2
[0045] Embodiment two, such as figure 2 As shown, the antenna device of this embodiment includes the V-shaped antenna 12, the first matching circuit 11, the shorting device and other main components. Wherein, the V-shaped antenna 12 is used as a directional antenna for forming a directional radiation magnetic field in a specific direction, so as to improve the wireless communication performance of the antenna device in a specific direction. The V-shaped antenna 12 of this embodiment is the same as that of Embodiment 1. It is preferably externally placed on an intelligent communication terminal. By setting a rotating part on the V-shaped antenna 12, the V-shaped antenna 12 can be freely rotated in a horizontal 360° direction, and then the The direction of polarization changes its radiation direction. The signal feed point 125 of the V-shaped antenna 12 is connected to the PCB substrate inside the intelligent communication terminal, and communicated with the first matching cir...
