Abstract

The invention provides an antenna system applied to a mobile terminal. The system comprises a first antenna, a second antenna, a third antenna, a fourth antenna, a first frequency selector, a second frequency selector, a WIFI module and a radio frequency unit, wherein the first antenna is connected with the WIFI module and the radio frequency unit through the first frequency selector; the second antenna is connected with the WIFI module and the radio frequency unit through the second frequency selector; and the third antenna and the fourth antenna are connected to the radio frequency unit separately. The antenna system can be designed through the first frequency selector and the second frequency selector, signals of different bands received by the antennas can be received and transmitted to the corresponding WIFI module and radio frequency unit separately, radiation bandwidths of the antennas can be effectively utilized to achieve a multi-antenna system, and furthermore, an MIMO WIFI can be well compatible with an LTE antenna to improve the sensitivity of LTE.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an antenna system and a mobile terminal. Background technique [0002] With the popularity of smartphones, the use of WiFi is becoming more and more widespread. As people have higher and higher requirements for the timeliness of accessing the network, Multi-input Multi-output (MIMO) technology and corresponding chips are more and more applied to mobile phone products, and WiFi data transmission technology is gradually changing from a single Antenna to multi-antenna transition. [0003] The continuous improvement of wireless access rate is a market demand, and MIMO antenna design has become an industry trend. Due to the stacking limitations of terminal modules and devices, and the limitation of multi-antenna isolation, MIMO antenna design has become a difficult point in terminal product design. [0004] In the existing technical solutions, the MIMO antennas in the mobile te...
