Abstract

The invention discloses an antenna switching system based on power and signal intensity detection. The system comprises at least two communication antenna groups, a global positioning system antenna, a wireless network antenna, a duplexer, a signal processing control module, a coupler and a double-pole-double-throw switch, wherein each communication antenna group is divided into two communication antennas so as to receive and transmit a mobile communication frequency range signal; the global positioning system antenna receives and transmits a global positioning system frequency range signal; the wireless network antenna receives and transmits a wireless network frequency range signal; the duplexer separates the mobile communication frequency range signal, the global positioning system frequency range signal and the wireless network frequency range signal; the signal processing control module detects receiving signal intensity; the coupler acquires reflection power; and the double-pole-double-throw switch is used to switch a usage antenna. The signal processing control module switches the usage antenna through the double-pole-double-throw switch according to the receiving signal intensity and the reflection power.

Description

technical field [0001] The invention relates to the technical field of mobile phones, in particular to an antenna switching system based on power and signal strength detection. Background technique [0002] With the development of technology and advancement of technology, smartphones, as a portable communication device, are trending in light, thin and small in appearance in order to meet the needs of the consumer market. At the same time, smartphones must be able to provide diversified services. This also means that more and more system modules and components will be installed in the limited space inside the smartphone, so the space for the most important antenna for wireless communication will be relatively compressed. [0003] After in-depth research on the existing technology, the traditional metal back mobile phone antenna needs to leave multiple gaps on the metal back cover for the antenna to radiate and receive in order to meet the needs of communication quality and si...
