Example Embodiment

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the specific embodiments of the antenna structure and the communication terminal having the antenna structure of the present invention will be described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0029] see figure 1 In one embodiment, the antenna structure is used as a back shell, which may include a sheet metal shell 100, a feeding port 300 and a resonant circuit. The sheet metal shell 100 is rectangular as a whole, and a slot 200 with a width of 0.5 mm to 5 mm is opened at a position close to one of the sides. The slit 200 is parallel to the side. The feeding port 300 is electrically connected to the sheet metal case 100 . Two ends of the resonant circuit are respectively connected to two sides of t...

Abstract

The invention discloses an antenna structure comprising a metal sheet case, a feed port, and a resonance circuit. The metal sheet case is in a rectangular shape; and a gap is formed in the position approaching one side, wherein the gap parallel to the side has the width of 0.5 millimeter to 5 millimeters. The feeding port is electrically connected with the metal sheet case. The two ends of the resonance circuit are connected with two sides of the gap of the metal sheet case. According to the antenna structure, multi-band working can be realized; because of the small size, the needed space is small; and the practicability is high. In addition, the invention also discloses a communication terminal having 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] With the development of mobile communication, more and more frequency bands are applied to mobile phones, which requires that mobile phones have good compatibility and can work on multiple frequency bands at the same time. This puts forward higher requirements for the built-in antenna of the mobile phone, not only to meet the requirements of miniaturization, but also to meet the requirements of working in multiple frequency bands at the same time. [0003] The method to realize the multi-band work of the mobile phone antenna is generally: setting multiple gaps of different lengths on the metal frame of the mobile phone, covering the upper and lower parts of the metal frame with non-metallic materials, increasing the size of the antenna, or adding multiple parasitic resonances, etc. Make the mobil...
