Problems solved by technology

[0004] When multiple antennas are integrated on a mobile device, due to size limitations, the mutual distance will become very small, which has a great impact on the radiation performance of each antenna, and even cannot meet the requirements of operators. This has become a Bottleneck in Antenna Design for Handheld Mobile Terminals

Abstract

The invention discloses a multi-band antenna and a mobile terminal. The multi-band antenna comprises a feed point, a grounding point, a super high frequency oscillator, a first ultrahigh frequency oscillator, a second ultrahigh frequency oscillator and a matching component. The feed point is used for being connected with a feeder line, the grounding point is used for being connected with a ground wire, the super high frequency oscillator is coupled to the feed point and the grounding point, the first ultrahigh frequency oscillator is coupled to the feed point and the grounding point, the second ultrahigh frequency oscillator is coupled to the feed point and the grounding point, and the matching component is coupled between the super high frequency oscillator and the first ultrahigh frequency oscillator and used for adjusting the coupling coefficient between the super high frequency oscillator and the first ultrahigh frequency oscillator. According to the technical scheme, the multi-band antenna has the advantages that a 2.4 GHz wireless network antenna, a Bluetooth antenna, a 5GHz wireless network antenna and a GPS receiving antenna are integrated on a metal sheet, in this way, the space, occupied by the antennas, inside the mobile terminal is reduced, the arrangement space of the antennas is more sufficient, the possibility of interference among the multiple antennas is reduced, and then arrangement of the antennas inside the mobile terminal is facilitated.

Description

technical field [0001] The invention relates to a radio frequency device, in particular to a multi-frequency antenna. . Background technique [0002] In the existing mobile communication system, 2G (second-generation mobile communication network standard) / 3G (third-generation mobile communication network standard) has been popularized. In some developed countries, 4G (fourth generation mobile communication network standard) LTE (Long Term Evolution "Long Term Evolution") has gradually become popular. [0003] Since the 4G communication system will become a necessity in the future, the support of the corresponding mobile terminal to the 4G network has also become a necessary requirement. Due to the requirements of the 4G standard, a 4G mobile terminal needs to be equipped with one more antenna than a 2G / 3G mobile terminal. In this way, in terms of antenna design, a 4G mobile terminal needs to reserve at least one more antenna position than a 2G / 3G mobile terminal. With th...
