[specific embodiment]

Please refer to shown in Fig. 1, the antenna 100 in longitudinally be extended, the antenna 100 include antenna body with And it is connected to feeder line 4 and metal foil 5 on antenna body.The antenna body include grounding parts 1, from grounding parts 1 be extended The first arm 2 and the second arm 3.In the present embodiment, the antenna body is formed in etching on substrate 200.In other realities It applies in example, the antenna body can also be stamped and formed out by sheet metal.

Shown in referring to figure 2., the grounding parts 1 are extended in longitudinally and have opposite first end 11 and second End 12.First arm 2 is extended from first end 11.First arm 2 includes the first vertical arm 21 and the first transverse arm 22, first transverse arm 22 from the first vertical arm 21 towards the second end 12 of the grounding parts 1 extend, first transverse arm 22 from An opening 222 is formed by end close to the second end 12 and with second end 12 and the second arm 3.First transverse arm 22 with connect The first slit 220 is formed between ground portion 1.Second arm 3 is extended from the second end 12 of grounding parts 1.Second arm Portion 3 includes the second vertical arm 31 and the second transverse arm 32, and second transverse arm 32 is from the second vertical arm 31 towards the first of the grounding parts 1 End 11 extends.The second slit 320 is formed between second transverse arm 32 and the first transverse arm 22.

The feeder line 4 has core wire 41 and the braiding layer 42 around 41 periphery of core wire.The feeder line 4 is connected to the opening 222, the free terminal of the first transverse arm 22 and the second end 12 of grounding parts 1 are connected so that first arm 2 with connect Second vertical arm 31 of ground portion 1 and the second arm 3 is formed into a loop around first slit 220.In the present embodiment, the core wire 41 free terminals for being connected to the first transverse arm 22 form signal feed-in point, and the braiding layer 42 is connected to close in the second vertical arm 31 To form ground connection load point at the second end 12 of grounding parts 1.Certainly, in other embodiments, the braiding layer 42 can also connect In on grounding parts 1.

In the present embodiment, the grounding parts 1, the first arm 2 and the second arm 3 are in the same plane, and described The height of two vertical arm 31 is greater than the height of first vertical arm 21, so that first arm 2 is located at the second arm 3 and grounding parts Between 1.The grounding parts 1 are 28.6mm in the length on longitudinally, and the height of second vertical arm 31 is 6mm.Fig. 3 is this The voltage standing wave ratio figure of invention antenna, the first arm 2 and grounding parts 1 of antenna 100 of the invention and the second of the second arm 3 are erected Arm 31 is formed by loop antenna and works in low frequency band, and the second transverse arm of second arm 3 is worked in because of coupling High-frequency band, by the way that the growth requirement of miniaturization can be met so set, make the antenna size smaller.

It should be pointed out that the foregoing is merely preferred forms of the invention, the embodiment being not all of, this field is general Any equivalent variation that logical technical staff takes technical solution of the present invention by reading description of the invention, is this hair Bright claim is covered.
