Abstract

The invention is applicable to the field of mobile terminals, and provides a mobile phone and an antenna thereof. The antenna comprises a first antenna branch, a second antenna branch, a third antenna branch, a first feed terminal, a second feed terminal, a third feed terminal and a phone metal ground, wherein the first, second and third antenna branches are sequentially arranged at one end of the mobile phone; the second antenna branch is positioned between the first and third antenna branches; the first feed terminal, the first antenna branch and the phone metal ground form a first antenna loop; the second feed terminal, the second antenna branch and the phone metal ground form a second antenna loop; the third feed terminal, the third antenna branch and the phone metal ground form a third antenna loop; through enabling all the antennal branches to be in the ground states, high fields are prevented from being tightly coupled through gaps among the antennas, so that even the three antennas are separated by about 1mm, mutual isolation among the three antennas also can be ensured, and thereby the three antennas respectively work normally.

Description

technical field [0001] The invention belongs to the field of mobile terminals, in particular to a mobile phone and an antenna thereof. Background technique [0002] With the advent of the 4G era, LTE (Long Term Evolution, long-term evolution) is no longer a concept but a trend. Due to the increase in 4G bandwidth, the requirements for mobile terminal antennas have also been significantly improved compared with 3G. For a dual-card dual-pass LTE mobile phone, in addition to the necessary two mobile main antennas, it also needs a diversity antenna, WIFI / BT antenna and GPS antenna. It is an urgent problem to be solved that the two antennas do not interfere with each other. The traditional implementation method is to increase the distance between the antennas as much as possible to achieve the isolation requirement between the antennas, but this method is obviously contrary to the trend of thinner and lighter mobile phones. To sum up, in the prior art, there is a problem of mut...
