Embodiments of the invention disclose an antenna selection circuit and a mobile terminal. The antenna selection circuit comprises a main WiFi antenna, an auxiliary WiFi antenna, a transfer switch, a control module and a WiFi module, wherein the transfer switch comprises a selection end, a main antenna connection end, an auxiliary antenna connection end and a control end, the main antenna connection end is connected to the main WiFi antenna, and the auxiliary antenna connection end is connected to the auxiliary WiFi antenna; the output end of the control module is connected to the control end,the input end of the control module is connected to the signal detection end of the WiFi module, and the input end of the WiFi module is connected to the selection end; the control module is used fordetecting the intensity of a WiFi signal received by the WiFi module and sending a switching signal to the transfer switch when the intensity of the WiFi signal is smaller than a preset intensity threshold value, and the switching signal is used for controlling the transfer switch to switch a WiFi antenna connected to the WiFi module. According to the embodiments of the invention, the WiFi antennaconnected to the WiFi module can be switched by detecting the intensity of the WiFi signal, so that the intensity of the WiFi signal received by the mobile terminal is ensured.
Description
technical field [0001] The invention relates to the technical field of terminals, in particular to an antenna selection circuit and a mobile terminal. Background technique [0002] At present, the WiFi antenna of mobile terminals such as mobile phones is generally installed on the top or bottom of the mobile phone. When the mobile phone is in a landscape state, the WiFi antenna is easily held by the palm of the hand, which may lead to poor antenna performance and weak WiFi signals. Contents of the invention [0003] Embodiments of the present invention provide an antenna selection circuit and a mobile terminal, which can improve the problem of weak WiFi signals. [0004] The first aspect of the embodiments of the present invention provides an antenna selection circuit, the antenna selection circuit includes a main WiFi antenna, a secondary WiFi antenna, a switch, a control module, and a WiFi module, wherein: [0005] The switch includes a selection end, a main antenna con...
