Problems solved by technology

[0004] In the process of realizing the above-mentioned technical solution, the inventor found at least the following problems in the prior art: when designing the mobile phone antenna, in order to enable the mobile phone antenna to work in different frequency bands, sometimes the bracket wiring inside the mobile phone needs to be in contact with the metal frame. At this time, since the contact position between the bracket wiring and the metal frame will be restricted by other structures of the mobile phone, it will be difficult to design the mobile phone antenna; in addition, the mobile phone antenna needs to be routed through the bracket, which will occupy a large space of the mobile phone and cause other structural problems in the mobile phone. Difficult to design

Embodiment 1

[0031] An embodiment of the present invention provides an antenna for a mobile terminal, referring to figure 1 As shown, the antenna of the mobile terminal includes: an N-section metal frame 100 of the mobile terminal, a metal ground layer 200, a feed circuit ( figure 1 Not shown in ) and the frequency switching device 400.

[0032] Wherein, the metal ground layer 200 is a rectangular plate structure, which is arranged in the casing of the mobile terminal and serves as the grounding of the antenna. Optionally, the area of ​​the metal formation 200 is the same as that of the mobile terminal, and is arranged in the middle of the mobile terminal housing; here, the area of ​​the metal formation 200 refers to the area of ​​a rectangle, and the area of ​​the mobile terminal may be the area of ​​the screen.

[0033] Optionally, the metal formation 200 is any conductive metal material. For example, the metal formation 200 is a magnesium-aluminum alloy material. The thickness of the...

Embodiment 2

[0062] The embodiment of the present invention also provides a mobile terminal, and the mobile terminal is provided with any one of the antennas shown in the first embodiment.

[0063] It should be noted that, for all antenna content involved in the mobile terminal embodiment, reference may be made to the specific description in the first method embodiment, and details are not repeated here.

[0064] To sum up, in the antenna of the mobile terminal provided by the embodiment of the present invention, the radiator of the antenna is a multi-segment metal frame of the mobile terminal, and no radiator is set inside the mobile terminal, so that the antenna transmits and receives signals no longer affected by the mobile terminal. Shell shielding and other influences, thereby improving the ability of the antenna to send and receive signals; moreover, when the radiator of the antenna is a multi-segment metal frame of the mobile terminal, it also saves space inside the shell of the mobi...

Abstract

Disclosed is an antenna of a mobile terminal, comprising N segments of metal frames of the mobile terminal, a metal ground layer, a feed circuit, and a frequency switching device, the N is an integer greater than or equal to 1; at least one of the N segments of metal frames is used for accessing the feed circuit by means of a feed point, the metal frame accessing the feed circuit serves as a radiator of the antenna, and the radiator radiates electromagnetic wave to make the antenna send and receive signals; the metal ground layer is provided in a shell of the mobile terminal; the frequency switching device is used for controlling different segments of metal frames to access the feed circuit so that the antenna words at different frequencies. Also disclosed is a mobile terminal provided with the antenna.

Description

technical field [0001] The present invention relates to terminal communication technology, in particular to a mobile terminal and its antenna. Background technique [0002] In order to make mobile terminals, such as mobile phones, look more and more fashionable and feel more comfortable, more and more metal materials are used to make mobile phone casings for existing mobile phones. However, when metal materials are used to make the mobile phone casing, the metal casing will block the transmission and reception of the mobile phone antenna signal, thereby causing the deterioration of the mobile phone signal. [0003] In order to solve this problem, the antenna of the mobile phone is currently designed in the following way: the metal frame of the mobile phone is used as a part of the radiator of the mobile phone, and combined with the bracket wiring inside the mobile phone to form the mobile phone antenna. [0004] In the process of realizing the above-mentioned technical solu...
