Abstract

The invention provides an antenna, an adjustment method thereof, and a mobile terminal, which relate to the technical field of communication and are used to solve the problem in the prior art that the adjustment of the antenna is not flexible enough to affect the radiation performance of the antenna. The antenna includes: a metal back shell ground, a metal radiation sheet, and an insulating medium connecting the metal back shell ground and the metal radiation sheet; a liquid metal adjustment part is provided in the insulating medium, and the liquid metal adjustment part includes Insulated pipe; the insulated pipe is in the shape of a zigzag between the metal back shell and the metal radiation sheet multiple times, wherein each turning point of the insulated pipe is in contact with the metal back shell or the metal radiation sheet contact; the pipe wall at each turning point is provided with an opening, and the opening is sealed by the metal back shell or the metal radiation sheet; the middle section of the insulating pipe is loaded with liquid metal, and the two ends of the insulating pipe Together with the liquid metal, a section of gas is enclosed in each case.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an antenna, an adjustment method thereof, and a mobile terminal. Background technique [0002] The all-metal mobile phone uses the metal back shell as the antenna radiation unit. Since the metal back shell is part of the shape ID, it cannot change the shape and size at will to achieve the best radiation like the traditional antenna; so in the metal back shell phone, the designer must not There is no need to use impedance tuning and electrical size tuning with the PCB board as the carrier to expand the frequency band width of the antenna. But both have their own limitations: Impedance tuning can improve the standing wave state of the antenna, but the radiation efficiency of the antenna is still limited by the radiation characteristics of the antenna itself; the electrical size tuning of the ground length of the switch with the PCB as the carrier is due to the cleara...
