Abstract

The invention provides an antenna and a mobile terminal. The antenna comprises a metal rear cover, an antenna feed-in end, a main matching circuit and an antenna resonance piece. A gap is formed in the metal rear cover. The metal rear cover is divided into an antenna radiation arm and a reference ground through the gap. One end of the antenna feed-in end is grounded, and the other end of the antenna feed-in end is connected with one end of the main matching circuit. The other end of the main matching circuit is connected with the antenna radiation arm. One end of the antenna resonance piece is connected with the antenna radiation arm, and the other end of the antenna resonance piece is suspended. According to the technical scheme of the invention, the initial impedance position of the antenna can be effectively changed. Meanwhile, the subsequent matching and tuning effect is ensured to be better and the antenna performance is improved.

Description

technical field [0001] The invention relates to the technical field of terminal antennas, in particular to an antenna with a metal back cover and a mobile terminal. Background technique [0002] At present, the metal back cover antenna in the mobile terminal, especially the GPS (Global Positioning System, Global Positioning System) & WIFI (Wireless Fidelity, Wireless Fidelity) multi-frequency antenna with the help of the metal back cover is very dependent on the quality of the initial impedance position of the antenna , if the initial impedance position of the antenna is not good, it is difficult to match the antenna performance to the optimum. Among them, the initial impedance position of the antenna is restricted by factors such as the position, length, and width of the gap on the metal back cover, and generally cannot be adjusted arbitrarily, making it difficult to take into account multiple frequency bands in antenna performance. [0003] In order to increase the bandwi...
