Embodiment 1
[0025] Embodiment one, such as figure 1 , figure 2 As shown, the antenna device of this embodiment includes main components such as a radiation body, a matching circuit 11 and a shorting device 15 . Wherein, the radiation body of this embodiment is provided with two radiation branches that can rotate relative to each other, which are respectively defined as a first radiation branch 12 and a second radiation branch 13 . Define the two ends of the first radiating branch 12 and the second radiating branch 13 as the head end and the end respectively, set the positions of the head end 121 of the first radiating branch 12 and the head end 131 of the second radiating branch 13 to be relatively fixed, and respectively The matching circuit 11 is connected to realize tuning of the resonant frequency of the antenna device through the matching circuit 11 . The end 122 of the first radiating branch 12 and the end 132 of the second radiating branch 13 are set as free ends, which can move...
Embodiment 2
[0045] Embodiment two, such as image 3 , Figure 4 As shown, the antenna device of this embodiment mainly includes a radiating body composed of a first radiating branch 32 and a second radiating branch 33, a directional matching circuit 30 for adjusting the matching impedance of a directional antenna, and a directional matching circuit 30 for adjusting the matching impedance of an omnidirectional antenna. Impedance omnidirectional matching circuit 31 and short circuit device 35 . Wherein, the first radiating branch 32 and the second radiating branch 33 are preferably arranged outside the casing of the intelligent communication terminal, and an angle adjustment part 34 and a rotating part 36 can be further arranged on the casing of the intelligent communication terminal, connected to The head end 321 of the first radiating branch 32 and the head end 331 of the second radiating branch 33 are convenient for adjusting the angle and turning of the two radiating branches 12 and 13...
