Abstract

The invention relates to a metal frame mobile phone antenna, a control system and a communication terminal. The metal frame mobile phone antenna includes a metal frame, and two seams are symmetricallyformed in both sides of one end of the metal frame; a first point of a grounding switch interface, a second point of the grounding switch interface, an electricity feeding input point and a third point of the grounding switch interface are sequentially arranged on the metal frame from one end of one seam at intervals. Through different connection points of the first point and second point of thegrounding switch interface, control over the coverage of high frequency and middle frequency is achieved, multiband frequency coverage of the antenna is ensured, and different inductors are connectedin a grounding unit to further refine medium frequency coverage; the communication capability of the metal frame antenna is improved, and the communication quality is ensured for users.

Description

technical field

[0001] The invention relates to the technical field of antennas, in particular to a metal frame mobile phone antenna, a control system and a communication terminal. Background technique

[0002] At present, with the development of 4G technology, the design of mobile terminal antennas such as metal frame mobile phones is particularly important. The design of the antenna is not exactly the same depending on the position of the metal frame slit, so an adjustable capacitor is used to achieve high and low frequency coverage of the antenna. also became common.

[0003] Metal frame mobile phone antennas in the prior art, such as Chinese utility model patents, application number: CN201620183065.9, disclose a metal frame mobile phone antenna, including a metal mobile phone frame, the metal mobile phone frame consists of a top frame, a bottom frame and The two side frames are surrounded by two slits, and the slits on the left and right sides are arranged symmetrically...
