Embodiment 1

[0020] The mobile terminal antenna system provided in this embodiment can be used in various mobile terminals. For example, the mobile terminal can include user equipment that communicates with one or more core networks via the radio access network RAN, and the user equipment can be Mobile telephones ("cellular" telephones), computers with mobile terminals, etc., e.g. user equipment can also be portable, pocket, hand-held, computer built-in or vehicle-mounted mobile devices that exchange voice and / or or data. For another example, the mobile terminal may include a mobile phone, a tablet computer, a personal digital assistant PDA, a sales terminal POS, or a vehicle-mounted computer.

[0021] figure 1 It is a schematic structural diagram of the mobile terminal antenna system provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the mobile terminal antenna system includes a metal support plate 1 and a hollow slot 2 arranged on the metal support plate 1; ...

Embodiment 2

[0029] image 3 It is a schematic structural diagram of the mobile terminal antenna system provided by Embodiment 2 of the present invention. The difference from Embodiment 1 is that the main antenna feed source in this embodiment is connected to the hollow slot through a frequency band adjustment circuit. Such as image 3 As shown, the mobile terminal antenna system includes a metal support plate 1 and a hollow slot 2 arranged on the metal support plate 1;

[0030] The above-mentioned hollow slot 2 is connected with the main antenna feed source 3 to form the main antenna system; the hollow slot 2 is connected with the NFC feed source 5 through the NFC matching circuit 4 to form the NFC antenna system; the NFC matching circuit 4 is used to debug the resonant frequency of the NFC antenna system , the main antenna feed 3 is connected to the hollow slot 2 through the frequency band adjustment circuit 6 .

[0031] Wherein, the frequency band adjustment circuit 6 is used to incre...

Embodiment 3

[0040] The mobile terminal provided in Embodiment 3 of the present invention includes the mobile terminal antenna system provided in the embodiment of the present invention.

[0041] Wherein, the mobile terminal may be a smart phone, a tablet computer, or a personal digital assistant.

[0042] preferred, see Figure 7 , the metal support plate 1 in the antenna system of the mobile terminal is integrally formed with the metal frame 12 of the mobile terminal casing, and the hollow slit 2 is opened in the metal support plate 1 .

[0043] The above-mentioned metal support plate 1 is located on the back shell of the mobile terminal, that is, the hollowed-out gap is inside the mobile terminal, so it will not affect the integrity of the appearance of the mobile terminal; and the metal support plate 1 is integrally formed with the metal frame 12 of the mobile terminal shell , the seamless connection between the two improves the strength and stability of the overall structure of the m...

Abstract

The invention discloses an antenna system for a mobile terminal and the mobile terminal. The antenna system of the mobile terminal comprises a metal support plate and a hollow gap, wherein the hollow gap is formed in the metal support plate and is connected with a main antenna feed source to form a main antenna system; the hollow gap is connected with a near-field communication (NFC) feed source through an NFC matching circuit to form an NFC antenna system; and the NFC matching circuit is used for debugging the resonant frequency of the NFC antenna system. According to the antenna system for the mobile terminal and the mobile terminal, the problem that the overall thickness of the mobile terminal is increased due to an NFC antenna structure employing an antenna coil and ferrite is solved; the number of antennas is reduced; the space of the mobile terminal is saved; and the cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a mobile terminal antenna system and a mobile terminal. Background technique [0002] At present, smart mobile terminals are generally designed with a Near Field Communication (NFC) system. NFC is an extremely short-range radio frequency identification communication protocol technical standard. NFC technology is mainly based on radio frequency technology operating at a frequency of 13.56MHz. The transmission range is small, but the transmission is fast and the energy consumption is low. [0003] Most mobile terminals use antenna coils and ferrite to realize the NFC function, that is, a piece of anti-metal absorbing material (ferrite) is pasted between the NFC module and the antenna coil, but this increases the thickness of the mobile terminal. Contents of the invention [0004] In view of this, the purpose of the present invention is to propose a mobile termin...
