Problems solved by technology

However, the introduction of functional modules corresponding to some functions will cause the mobile terminal LTE (Long Term Evolution, Long Term Evolution) main antenna to be integrated with the GPS (Global Positioning System, Global Positioning System) antenna and WiFi (Wireless-Fidelity, Wireless Fidelity) antenna. Located above the whole machine, the distance between the antennas is obviously less than 1 / 2 of the signal wavelength, resulting in mutual coupling between the antennas
Mutual coupling between antennas can seriously affect signal reception performance between wireless systems

Embodiment Construction

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0031] Due to the introduction of some functional modules in the mobile terminal, the available space of the antenna of the mobile terminal will be compressed, and the distance between various antennas of the mobile terminal is small, resulting in problems such as mutual coupling and electromagnetic interference between the antennas, which affect the performance of the antenna. For example, since the fingerprint module is integrated with the home button of the mobile phone, and the earphone module is placed at the bottom, there is less sp...

Abstract

The invention provides an antenna device and a mobile terminal. The antenna device comprises a first antenna assembly, a second antenna assembly, a first inductor and a second inductor, wherein the first antenna assembly is connected with a motherboard via a first feed point; the second antenna assembly is connected with the motherboard via a second feed point; the first end of the second antenna assembly is adjacent to the first end of the first antenna assembly; the first end of the first inductor is grounded, and the second end of the first inductor is connected with the first end of the first antenna assembly; and the first end of the second inductor is grounded, and the second end of the second inductor is connected with the first end of the second antenna assembly. According to the embodiment of the invention, the isolation degree between antennas can be improved, and mutual interference between systems can be reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an antenna device and a mobile terminal. Background technique [0002] With the continuous development of mobile terminals, there are more and more functions of mobile terminals, such as fingerprint functions such as camera function, fingerprint unlocking, and fingerprint payment. However, the introduction of functional modules corresponding to some functions will cause the mobile terminal LTE (Long Term Evolution, long-term evolution) main antenna to be integrated with the GPS (Global Positioning System, Global Positioning System) antenna and WiFi (Wireless-Fidelity, Wireless Fidelity) antenna. Located above the whole machine, the distance between the antennas is obviously less than 1 / 2 of the signal wavelength, which leads to mutual coupling between the antennas. Mutual coupling between antennas can seriously affect signal reception performance between wireles...
