Signal enhancement circuit and system and implementation method thereof

Abstract

The invention discloses a signal enhancement circuit and system and an implementation method thereof. The circuit comprises a first antenna, a second antenna, an actual mobile phone antenna and an antenna switch, wherein the first antenna is used for carrying out debugging of an optimal signal when a mobile phone is held in the left; the second antenna is used for carrying out debugging of the optimal signal when the mobile phone is held in the right; the actual mobile phone antenna is used for receiving a mobile phone signal after passing through the first antenna or the second antenna; the antenna switch is used for controlling the connected antennas according to the posture that the user holds the mobile phone and carrying out switching between the first antenna and the second antenna; the antenna switch, a circuit formed by connecting the first antenna and the second antenna in parallel and the actual mobile phone antenna are sequentially connected; the antenna switch is controlled to be switched into the first antenna or the second antenna; debugging of the optimal signal is carried out on the first antenna or the second antenna through a voltage standing wave ratio of the mobile phone signals in the antennas; and the debugged mobile phone input signal is output to the actual mobile phone antenna. The effect of amplifying the mobile phone signals is achieved through optimizing antenna channels and switching the antennas.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a signal enhancement circuit, system and implementation method thereof. Background technique [0002] When using mobile terminals such as smart phones and tablet computers, the phenomenon of signal weakening often occurs, that is, when browsing the web or making a phone call, the web page is stuck, and the voice of the mobile phone is also intermittent. This is because the human body will keep moving when using a mobile phone or a tablet computer, or changing hands of a mobile terminal. During the process of moving or changing hands, it may move from a position with a better signal to a position with a weaker signal. The signal received by the terminal from the base station becomes weaker. At this time, the base station is easy to drop the line when talking with the mobile phone. [0003] Therefore, the prior art still needs to be improved and developed. Conte...
