no. 1 example

[0042] like figure 1 As shown, in the antenna device provided in this embodiment, the conductive bottom plate 1 is configured as a plate with a protruding portion 11 . The conductive bottom plate 1 can be made of a conductive metal material, the purpose is to realize the current of the antenna device being introduced to the metal substrate 9 of the mobile terminal through the raised part, and at the same time use the metal structure around it to radiate, so as to realize the communication signal of the mobile terminal. send and receive. The grounding frame 2 is constructed in a U-shape, thereby enclosing the conductive base plate 1, and an insulating gap 7 is provided between the grounding frame 2 and the conductive base plate 1. isolation, wherein the raised portion 11 extends away from the ground frame 2 and toward the metal substrate 9 . The electrical conduction between the conductive bottom plate 1 and the ground frame 2 is realized through the first shorting rod 3 and ...

[0052] like figure 1 As shown, the terminal provided in this embodiment includes a middle frame, a metal substrate 9 and the above-mentioned antenna device. Among them, the middle frame shown in the figure is U-shaped, the metal substrate 9 is accommodated in the middle frame, and the ground frame 2 in the antenna device is docked with the middle frame to form a rectangular frame of the mobile terminal, wherein the raised part is connected to the metal Substrate9. Further, the metal substrate 9 is integrally formed with the conductive bottom plate 1 .

[0053] Figure 11 and Figure 12 In the case where the terminal with the antenna device in this embodiment is held in the left hand and the right hand, the radiation efficiency curves at different frequencies are given, the horizontal axis is the frequency (Frequency), the unit is GHz, and the vertical axis is the total efficiency Total Efficiency. The solid line is the radiation efficiency curve of the antenna device in t...

Abstract

The invention provides an antenna device and a terminal. The antenna device comprises a conductive bottom plate, a grounding frame and an antenna shorting assembly, wherein the conductive bottom plate is in a plate form with a boss; the grounding frame comprises a conductive bottom plate; an insulating gap is arranged between the grounding frame and the conductive bottom plate; the boss departs from the grounding frame and extends towards a metal substrate; the antenna shorting assembly comprises a first shorting rod, a second shorting rod and a control part; and the first shorting rod and the second shorting rod are electrically connected with the conductive bottom plate and the grounding frame alternately under the control of the control part, so that the influence of a body of a user on a transmitted signal in the using process is reduced.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an antenna device and a terminal. Background technique [0002] With the continuous growth of user demand, mobile terminals with metal appearance appear in the mobile terminal market, and users have higher requirements for the antenna performance of such terminals, especially the antenna body with metal appearance is set on the first-level appearance surface , so that the user has the opportunity to directly touch the antenna, thereby reducing the efficiency of the antenna and failing to work well. Therefore, there is a need for an antenna device and a terminal to solve the above-mentioned technical problems existing in the prior art. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an antenna device and a terminal, which reduce the influence of the user's body on the transmitted signal during use. [0004]...
