Abstract

The invention provides an antenna system and a terminal. The antenna system is applied to the terminal with a metal body. A gap filled with non-metal material is arranged on the metal body. The metalbody is separated through the gap to form a resonant arm and a coupling arm. The antenna system includes the resonant arm, the coupling arm, a feed source circuit, a first tuning circuit and a secondtuning circuit. A first end of the feed source circuit is connected with a first feed point of the resonant arm. A second end of the feed source circuit is grounded. A first end of the first tuning circuit is connected with a second feed point of the resonant arm. A second end of the first tuning circuit is grounded. A first end of the second tuning circuit is connected with a third feed point ofthe coupling arm. A second end of the second tuning circuit is grounded. The first tuning circuit includes N parallel capacitors, and N is an integer greater than 1. The system can extend tuning bandwidth of the antenna system.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an antenna system and a terminal. Background technique [0002] With the development and progress of science and technology, communication technology has developed rapidly and made great progress. With the improvement of communication technology, the popularity of electronic products has reached an unprecedented height. More and more terminals such as mobile phones, smart TVs and computers Waiting to become an integral part of people's lives. [0003] With the popularization of terminals, users have higher and higher requirements for the types of functions and performance of terminals, such as audio functions, camera functions, camera functions, and fast charging functions, etc., have become essential functions of terminals. [0004] As the functions of the terminal become more and more perfect, the appearance and texture of the terminal have ...
