Embodiment 1
[0040] refer to figure 1, the antenna of the first embodiment of the present invention is proposed, the antenna includes an antenna body 10, a tuning device 20 and a coupling device 30, the coupling device 30 is connected to the tuning device 20, and the antenna body 10 is neither connected to the tuning device 20 nor connected to the The coupling device 30 is connected, but spaced apart from the coupling device 30 by a coupling interval, so as to be coupled with the coupling device 30, thereby realizing coupling tuning. The coupling distance can be set according to actual needs, usually between 0.1 mm and 3 mm, preferably between 0.2 mm and 0.3 mm.
[0041] The coupling described in the embodiment of the present invention refers to the close cooperation and mutual influence between two or more antenna components. By changing the parameters of one of the antenna components, the parameters of the entire antenna can be indirectly changed, thereby achieving the effect on One sid...
Embodiment 2
[0046] refer to figure 2 , the antenna of the second embodiment of the present invention is proposed. The difference between this embodiment and the first embodiment is that the antenna body 10 includes two branch units. In addition to the feed source branch 12, it also includes a ground branch 13, which is connected to the ground branch 13. location, the first coupling unit 31 is located on one side of the two branch units. Such as figure 2 As shown, the first coupling unit 31 is adjacent to the feed branch 12 (or adjacent to the ground branch 13 in some embodiments), and is separated from the feed branch 12 by a coupling distance D. Wherein, the coupling position between the feed branch 12 and the first coupling unit 31 is approximately at the position of 1 / 3 to 2 / 3 of the feed branch 12 (of course, it can also be located at other positions), and the distance between the feed branch 12 and the main body The connection point of the unit 11 is closer than the feed point (a...
Embodiment 3
[0048] refer to image 3 , the antenna of the third embodiment of the present invention is proposed. The difference between this embodiment and the second embodiment is that the first coupling unit 31 is located between the two branch units of the antenna body 10, that is, between the feed source branch 12 and the ground branch 13. and a coupling distance D from the ground branch 13 (in some embodiments, it may also be separated from the feed branch 12 by a coupling distance), that is, the coupling device 30 is closer to the ground point than the feed point. Wherein, the coupling position of the ground branch 13 and the first coupling unit 31 is about 1 / 2 of the position of the ground branch 12 (of course, it can also be located at other positions); the coupling position of the main body unit 11 and the second coupling unit 32 is approximately at the main body 1 / 3 to 2 / 3 of the unit 11 (of course it can also be located at other positions), and it is closer to the grounding poi...
