[0005] At present, most mobile terminal (mobile phone) products require a wide bandwidth at low frequencies, covering from 700Mhz to 960Mhz. Usually, antenna debugging alone cannot cover such a wide bandwidth. The common practice is to use antenna tuning switches to tune to increase bandwidth. Will bring some performance loss

The invention relates to the technical field of mobile terminals, and discloses a method and system for reducing antenna tuning switch loss of a mobile terminal. The method comprises the following steps: setting a section of antenna routing with a preset length in parallel out of a built-in antenna of the mobile terminal in advance, and connecting the antenna routing to an antenna tuning switch; when the antenna is used for the first preset frequency band communication, enabling the antenna tuning switch to be in an off state, and suspending the antenna routing connected with the antenna tuning switch not to work; when the antenna is used for the second preset frequency band communication, enabling the antenna tuning switch to be in an on state, connecting the antenna routing connected with the antenna tuning switch to the GND pin, and enabling the antenna tuning of the mobile terminal to deviate to the second preset frequency band. Through the adoption of the method disclosed by the invention, the antenna routing connected with the antenna tuning switch is acted as a parasitic routing mode; the switch is turned on when some frequency bands use the switch so that the parasitic irradiator plays effect; the switch is turned off when other frequency bands do not use the switch so that the parasitic irradiator is suspended; therefore, the switch loss can be avoided.
Description
technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and a system for reducing antenna tuning switching loss of a mobile terminal. Background technique [0002] There are many fields of bandwidth application, which can be used to identify the data transmission capability of signal transmission, the amount of data passing through the link per unit time, and the display capability of the display. [0003] Also known as bandwidth in analog signal systems, it refers to the amount of data that can be transmitted at a fixed time, that is, the ability to transmit data in a transmission pipeline. Usually expressed in transmission cycles per second or hertz (hz). [0004] A tuned antenna is an antenna that has a predetermined directivity only in a very narrow frequency band, called a tuned antenna or a tuned directional antenna. Typically, the directivity of a tuned antenna remains constant only in the 5% band ar...
