[0024] The terminal antenna proposed by the utility model and the laptop computer using the terminal antenna are further described in detail below in combination with the accompanying drawings and specific embodiments. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. In addition, the structure shown in the accompanying drawings is often a part of the actual structure. In particular, the emphasis of each accompanying drawing is different, and sometimes different proportions are used.

[0025] like Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model provides a terminal antenna, which is applied to a laptop computer, and the laptop computer includes a first shell C and a second shell D corresponding to the first shell C, the terminal antenna includes a radiating antenna body 10 and a slot 20 opened in the first shell C, the radiating antenna body 10 is built between the first shell C and the second shell D, and the first shell C covers part of the radiating antenna body 10; the radiating antenna body 10 includes a feeding point 11, a grounding point 12, a first radiating branch 13, a second radiating branch 14 and a third radiating branch 15 connected to the grounding point 12, and the first radiating branch 13 is electrically connected to the feeding point 11.

[0026] Specifically, a slot 20 is provided on the first shell C of the laptop computer. Preferably, the first shell C is made of metal. The radiation antenna body 10 is coupled with the slot 20 for radiation. This design can not only reserve the metal side frame C1, but also greatly improve the radiation performance of the radiation antenna body 10. The radiation antenna body 10 is coupled with the slot 20 for radiation, which can avoid destroying the integrity of the whole structure, and can also improve the radiation performance of the antenna and reduce the difficulty of antenna debugging.

[0027] Furthermore, the slot 20 is provided at an edge position close to the first shell C, and the slot 20 is provided in an L shape. The slot 20 includes a first slot 21 and a second slot 22 which are connected to each other, and the edge of the first shell C is broken and vertically extended to form the first slot 21. Of course, the shape of the slot 20 in the utility model can also be other forms, as long as it can cooperate with the radiating antenna body 10 to improve the antenna radiation performance and reduce the difficulty of antenna debugging, and no excessive restrictions are made here.

[0028] As an embodiment of the utility model, the slot is an L-shaped narrow slot 20, one end of the second slot 22 is connected to the first slot 21, and extends in a direction parallel to the edge of the first shell C. The first radiation branch 13 is coupled and connected to the third radiation branch 15, and the second radiation branch 14 is connected to the third radiation branch 15. The grounding point 12 is electrically connected to the third radiation branch 15, the third radiation branch 15 is connected to one end of the second radiation branch 14, and is coupled and connected to the first radiation branch 13, the feeding point 11 is electrically connected to the first radiation branch 13, and the feeding point 11 is close to the grounding point 12, so that the excitation of the antenna can be effectively improved, and the coupling connection of the partial radiation antenna body 10 with the slot 20 effectively improves the overall radiation performance of the antenna.

[0029] Further, the edge shell near the second slot 22 covers the third radiation branch 15, and the third radiation branch 15 is parallel to the edge of the first shell C. The second radiation branch 14 is vertically connected to the third radiation branch 15, and the second radiation branch 14 is arranged in an L shape. The projection of the first radiation branch 13 and the projection of the second radiation branch 14 are both within the second slot 22. The gaps around the first radiation branch 13 and the second radiation branch 14 are filled with plastic.

[0030] Specifically, there is a metal side frame C1 next to the second slot 22, and the metal side frame C1 is reserved to be used as a ground, which can parasitize high-frequency branches and couple with the radiating antenna body 10, which can effectively improve the overall passive efficiency of the antenna and the performance of the air download technology. The port C2 of the first slot 21 is the disconnection position of the metal frame of the first shell C. The function of the disconnection is to use the side frame, that is, the metal side frame C1, as a parasitic branch grown from the ground. Therefore, the port C2 of the first slot 21 must be disconnected. If it is not disconnected, the performance of the antenna's air download technology will be very poor. The second shell D is a non-metal material located opposite the first shell C. The second shell D is partially opened with a window. The area where the radiating antenna body 10 maps the second shell D is all non-metal material. If there is no window setting, it will seriously affect the overall passive efficiency of the antenna and the performance of the air download technology.

[0031] Preferably, the terminal antenna of the present invention is in the form of a monopole antenna, and the metal side frame C1 can be regarded as a high-frequency band parasitic from the location. The high-frequency band is coupled and connected with the first radiation branch 13 to generate a 700MHz-960MHz frequency band, and the medium and high frequency parts are generated by the resonance of the first radiation branch 13 and the second radiation branch 14. Preferably, the radiation antenna body 10 in the present invention is built into the lower right corner of the first shell C of the laptop computer, and the radiation antenna body 10 is partially attached to the inner side of the first shell C. Plastic is used to fill part of the radiation antenna body 10 and the first radiation branch 13 and the second radiation branch 14 with the slot, that is, part of the radiation antenna body 10 is attached to the inner side of the first shell C, and the other part of the radiation antenna body 10 is attached to the plastic.

[0032] like Figure 4 As shown, it is a simulation diagram S11 of the entire antenna without the slot 20 and without disconnecting the metal side frame C1 of the first shell C; Figure 5 As shown, it is a simulation diagram S11 of the entire antenna with the slot 20 opened and the metal side frame C1 of the first shell C cut off. Figure 4 and Figure 5 By comparison, we can see that in the low-frequency part, Figure 5 The antenna design is obviously due to Figure 4 The antenna design in the antenna is improved, and the overall passive efficiency of the antenna is also significantly improved.

[0033] In summary, the utility model is applied to a laptop computer through a terminal antenna, the laptop computer includes a first shell C and a second shell D corresponding to the first shell C, the terminal antenna includes a radiation antenna body 10 and a slot 20 opened in the first shell C, the radiation antenna body 10 is built between the first shell C and the second shell D, and the first shell C covers part of the radiation antenna body 10; the radiation antenna body 10 includes a feeding point 11, a grounding point 12, a first radiation branch 13, a second radiation branch 14 and a third radiation branch 15 connected to the grounding point 12, and the first radiation branch 13 is electrically connected to the feeding point 11. The terminal antenna of the utility model can not only effectively reduce the difficulty of antenna debugging, but also effectively improve the radiation performance of the antenna under the full metal terminal.
