Problems solved by technology
When the mobile phone is doped with metal technology, the metal part of the mobile phone (especially the metal frame) will become the interference source of the antenna. At this time, the electromagnetic wave of the antenna cannot be effectively radiated, and the overall performance of the antenna is greatly reduced, which seriously affects people's normal communication.

Abstract
The invention relates to an antenna structure and discloses a metal frame based antenna module and a mobile device. The metal frame based antenna module comprises a metal-frame antenna body, an insulating support, a feed part, a feed-ground part, a first switch and a second switch; the metal frame antenna body is a first portion of a metal frame of the mobile device; the feed part and the feed-ground part are arranged to the insulating support respectively; the metal-frame antenna body is provided with a feed end, a first feed-ground end and a second feed-ground end arranged in sequence; the feed end is connected to the feed part, the first feed-ground end is connected to a grounding portion of the mobile device through the first switch, and the second feed-ground end is connected to the feed-ground part through the second switch. The metal frame of the mobile device is a radiation carrier of the antenna, interference of the metal frame to the antenna is reduced, meanwhile working modes of the antenna are switched in real time through the two switches, the mobile device is kept under the optimum communication status constantly, and communication quality of the mobile device in different frequency bands is improved effectively.
Description
technical field [0001] The invention relates to an antenna structure, in particular to an antenna module based on a metal frame and a mobile device. Background technique [0002] In recent years, as the era of smart phones has become more and more popular, mobile phone antennas are facing serious challenges. The coming of the age of metal machines with good feel and exquisite appearance has subverted people's perception of metal. [0003] The current mobile phone antennas are mainly PIFA, IFA, Monopole and other types of antennas, and these traditional antennas have higher requirements on the overall environment of mobile phones. When the mobile phone is doped with metal technology, the metal part of the mobile phone (especially the metal frame) will become the interference source of the antenna. At this time, the electromagnetic wave of the antenna cannot be effectively radiated, and the overall performance of the antenna is greatly reduced, which seriously affects people'...
