Antenna multiplexing device and mobile terminal

Abstract

The invention discloses an antenna multiplexing device. The antenna multiplexing device comprises a Cellular main antenna, at least one Cellular diversity antenna, a WLAN antenna, a first radio-frequency switch, a second radio-frequency switch, a first communication module, a second communication module and a gating module; one end of the first radio-frequency switch is connected with the first communication module; one end of the second radio-frequency switch is respectively connected with the first communication module and the second communication module; the second communication module comprises a multiplexing port and an antenna connection port; and the second communication module is connected with the second radio-frequency switch through the multiplexing port and connected with the WLAN antenna through the antenna connection port. According to the antenna multiplexing device and the mobile terminal provided by the invention, the main antenna and the WLAN antenna form a MIMO antenna in a first working mode through the gating module; therefore, the relevancy of the MIMO antenna in multiple frequency bands can be reduced; and the antenna efficiency can be increased.

Description

technical field [0001] The present invention relates to the technical field of antenna multiplexing, and more particularly relates to an antenna multiplexing device and a mobile terminal. Background technique [0002] With the development of wireless communication, usually there is only one antenna for a wireless communication terminal (such as a mobile phone) to realize a voice call, and at least one WLAN antenna is required to realize a WLAN (Wireless Local Area Networks, wireless local area network) function (such as a Bluetooth function or a WLAN function). , the position of the WLAN antenna is different from the position of the aforementioned antenna for voice communication. When the user of the wireless communication terminal is in a certain area, due to the position and direction, there is a certain change in the strength of the antenna signal, and at this time there will be different signal strengths in different directions. [0003] At present, mainstream wireless ...

Problems solved by technology

[0006] However, this solution does not take into account the correlation between WLAN MIMO antennas and Cellular diversity antennas

Among them, in the mainstream layout scheme, the WLAN MIMO antenna is very close to the cellular diversity antenna, and its isolation is generally very low, resulting in a high correlation between the two antennas that constitute MIMO, which does not meet the requirements of MIMO for antennas.
