Abstract

The present invention discloses an antenna structure. The antenna structure is used for taking ad a base shell and comprises a metal floor, a metal frame, a feeding port, a matching circuit, a resonance circuit and a parasitic branch knot. A slit with a width in the range from 0.5mm to 3mm is arranged between the metal floor and the metal frame; the feeding port is electrically connected with the metal floor and is electrically connected with the metal frame through the matching circuit; and one end of the parasitic branch knot is electrically connected with the metal floor through the resonance circuit. The antenna structure is able to realize multi-band frequency work, and is small in size and required space and high in practicality. The present invention further discloses a mobile terminal with the antenna structure.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a mobile terminal and its antenna structure. Background technique [0002] To meet the demand for small wireless devices, manufacturers are constantly striving to realize wireless communication circuits, such as antenna assemblies, in compact structures. At the same time, it may be desirable to include conductive structures in electronic devices, such as metal device housing components. Because conductive components can affect radio frequency performance, care must be taken when incorporating antennas into electronic devices that include conductive structures. The metal frame mobile phone antenna solution is often not conducive to performance due to the size of the antenna space available on the device. Contents of the invention [0003] Based on this, it is necessary to provide an antenna structure capable of working in multiple frequency bands and having a small si...
