Fig. 1 is a kind of structural representation of present invention smart mobile phone LCD metallic plate active antenna.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Existing smart mobile phone is by the coupling element of antenna and circuit board ground, and LCD generally metal material, typically
Positioned at the underface of circuit board, have impact on the performance of circuit board active antenna.The LCD metallic plate active antenna of the present invention directly will
Coupling element and LCD metal plate earthing, so that coupling element directly excites LCD metallic plate to make up to radiation effect.
As shown in figure 1, a kind of smart mobile phone LCD metallic plate active antenna of the present invention, including LCD metallic plate 10, coupling
Element 20 and feeder line 30；LCD metallic plate 10 place plane is located at below circuit board 50 plane and is put down with circuit board plane
OK；Coupling element 20 place plane is two different planes from LCD metallic plate 10 plane, and coupling element 20 passes through earth lead
Road 40 is connected with LCD metallic plate 10, is additionally provided with the first matching element 21 between coupling element 20 and ground path 40；Feed
Circuit 30 is located in circuit board plane, and one end of feeder line 30 is connected to signal source, and the other end of feeder line 30 passes through the
Two matching elements 31 are connected to circuit board 50.
Coupling element 20 place plane is two different planes from LCD metallic plate 10 plane, and for example, coupling element 20 can
With in circuit board 50 plane；Or, coupling element 20 place plane is located above circuit board 50 plane and is put down with circuit board
Face is parallel；Or, coupling element 20 place plane is vertical with LCD metallic plate 10 plane.Coupling element 20 and LCD metal in Fig. 1
Position relationship between plate 10 is only schematically, and should not be used as limiting the scope of the invention.
