Abstract

The invention provides an antenna system, a terminal and an antenna frequency adjustment method. The antenna system at least comprises a first antenna body, a first feed unit, and a metal shell arranged on the back of a terminal. The metal shell is at least provided with a first gap along a first direction, and the first gap and the metal shell form a first metal area and a second metal area. The first antenna body is arranged in a position, near the first gap, in the first metal area, and is partially coupled to the metal in the first metal area to form a first antenna. The first feed unit is arranged in a position, near the first gap and corresponding to the first antenna body, in the second metal area. The first antenna is coupled through the first gap to the first feed unit for feeding. The antenna system further comprises a first antenna switch which is used for tuning the frequency of the first switch and is arranged in a position, near the first feed unit, in the second metal area. According to the antenna system, different frequencies excited by the first antenna are tuned flexibly by the first antenna switch, so that the antenna system has wider bandwidth coverage.

Description

technical field [0001] The present invention relates to the communication field, in particular to an antenna system, a terminal and an antenna frequency band adjustment method. Background technique [0002] With the popularization and development of communication terminals, users' requirements for the appearance of communication terminals are also constantly increasing. Subsequently, more and more communication terminals with metal appearance appear on the market, but most communication terminals with metal back covers often have antennas. The problem of imperfect design, such as the inability to flexibly perform antenna tuning or realize multi-antenna design, makes the communication terminal unable to meet the operator's requirements for antenna performance. Contents of the invention [0003] An antenna system, a terminal, and an antenna frequency band adjustment method provided by the embodiments of the present invention mainly solve the technical problem that the antenn...
