Problems solved by technology

This multi-band antenna implementation method needs to be realized by adding radio frequency devices (for example, antenna brackets) and LDS (Laser Direct Structuring, laser direct structuring) devices, but this method will increase the layout area of ​​the antenna and lead to thicker mobile terminals , does not meet the requirements of slim appearance, and this method will inevitably increase the cost of antenna design

Abstract

The invention provides an antenna system and a mobile terminal. A first metal frame of the antenna system is connected with a metal floor through connection bar positions; a first slot is formed between the first metal frame and the metal floor; one end of a second metal frame is connected with the metal floor; the second metal frame is extended parallel to the lateral side of the metal floor; a second slot is formed between the second metal frame and the metal floor; the end of the first metal frame faces the end of the second metal frame; a slot for providing coupling excitation is arrangedbetween the opposing ends of the first and second metal frames. A radio frequency signal source is electrically connected with the first metal frame or the second metal frame through a matching network so as to form a multi-frequency antenna. The antenna system herein can provide multi-frequency signal communication through one antenna, antenna layout area is saved, antenna design cost is reduced,and implementation of a light and thin body of the mobile terminal is benefited.

Description

technical field [0001] The present invention relates to the technical field of multi-band antennas, in particular to an antenna system and a mobile terminal. Background technique [0002] With the continuous development of mobile terminals, people have higher requirements for the appearance size and equipment performance of mobile terminals. At present, mobile terminals that are widely concerned by people need to be thin and light and capable of supporting multi-band antennas (for example, GPS antenna, WIFI 2.4G antenna, WIFI 5G antenna, etc.) communication characteristics. For the multi-band antenna communication function of mobile terminals, the market usually uses three different frequency band signals to be split into two antennas, one of the two antennas works in dual frequency, and the other works in single frequency. And adjust the corresponding frequency band mode of each antenna according to the demand, and realize the communication function of multi-band signal th...
