Embodiment 2

[0031] Figure 7 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 there are four slits on the metal frame in this embodiment, and the metal frame is divided into four sections. Each metal frame Antenna structures with different functions are formed with different antenna modules. Such as Figure 7 As shown, the mobile terminal antenna system includes a metal frame of the mobile terminal, an NFC feed 2, a first matching circuit 3, a diversity antenna feed 4, a second matching circuit 5, a zeroth inductance 6 and a reference ground 7; the above metal frame There are four gaps 8 on the top, and the metal frame is divided into the first metal frame 9, the second metal frame 10, the third metal frame 11 and the fourth metal frame 12; each gap 8 can be filled with plastic to connect each section of metal frame.

[0032]Among them, the NFC feed 2 is connected to th...

Embodiment 3

[0041] 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. The mobile terminal uses its metal frame as an antenna radiator, and at least two slits are opened on the metal frame to divide the metal frame into at least two sections, one of which is integrated with an NFC antenna structure and a diversity antenna structure, saving the space of the mobile terminal , reducing the cost of the antenna.

[0042] Wherein, the mobile terminal may be a smart phone, a tablet computer, or a personal digital assistant.

[0043] The mobile terminal provided by Embodiment 3 of the present invention includes the mobile terminal antenna system provided by the embodiment of the present invention, and has corresponding functions and beneficial effects.

Abstract

The invention discloses a mobile terminal antenna system and a mobile terminal. The antenna system comprises a metal frame of the mobile terminal, an NFC feed source, a first matching circuit, a diversity antenna feed source, a second matching circuit, a zeroth inductor and reference ground; at least two slots are formed in the metal frame; a metal frame section between any adjacent slots is a first metal frame; the NFC feed source is connected with the first metal frame through the first matching circuit; the diversity antenna feed source is connected with the first metal frame through the second matching circuit; one end of the zeroth inductor is connected with the first metal frame, and the other end of the zeroth inductor is grounded; the NFC feed source, the first matching circuit, the first metal frame, the zeroth inductor and the reference ground form an NFC antenna system; the diversity antenna feed source, the second matching circuit and the first metal frame form a diversity antenna system; and the NFC antenna system and the diversity antenna system share the first metal frame as an antenna radiating body. With the mobile terminal antenna system of the invention adopted, the problems of large occupied space and high cost of a mobile terminal built-in antenna can be solved.

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) function, and accordingly, an NFC antenna is required to implement the NFC function. 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. Its transmission range is small, but transmission is fast and energy consumption is low. [0003] In an intelligent mobile terminal, multiple antennas such as a Global Positioning System (GPS) antenna, a Wireless Fidelity (Wi-Fidelity, WiFi) antenna, a diversity antenna, and a main antenna are often provided. It is built on the motherboard of the mobile terminal, and the NFC antenna is designed sepa...
