Abstract

The invention discloses a mobile terminal WIFI antenna system, a control method and a mobile terminal. The mobile terminal WIFI antenna system comprises a built-in antenna arranged in the mobile terminal, a signal intensity detection circuit and a radio frequency change-over switch which are respectively connected with the built-in antenna, and an external antenna which is electrically connected with the radio frequency change-over switch, wherein the radio frequency change-over switch is connected with the signal intensity detection circuit; and the radio frequency change-over switch selectsand switches a WIFI antenna of the mobile terminal into an external antenna according to the signal intensity received by the built-in antenna and detected by the signal intensity detection circuit when the signal intensity is smaller than preset intensity. According to the embodiment of the invention, the external module or the rear shell of the existing mobile terminal is shared, and the antennaradio frequency switch is added and the main radio frequency circuit is connected through a coupled feeding or direct contact method, so that the WIFI antenna function is realized, and the antenna space is saved, and the wireless performance of the mobile terminal in a weak signal environment is improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile terminal WIFI antenna system, a control method and a mobile terminal. Background technique [0002] With the popularity of full-screen mobile phones, greater challenges are posed to the space and performance of WIFI antennas. The circuit boards of existing smartphones have limited space for WIFI antennas. With the rapid increase in users' demand for Internet access speeds, improving WIFI signals to further enhance users' online experience is an urgent problem that needs to be solved in the design of smart phones. In the existing technology, multiple antennas of smartphones coexist, and the antenna environment is relatively harsh, and the external antenna requires a large antenna space. It is difficult to effectively improve the antenna performance of existing products in the case of weak signals; currently, smartphones are a main The scheme of transmitting antenna an...
