Abstract

The invention provides a method for debugging signal transduction and an antenna. A signal is outputted to a signal test device connected with the front end of a signal processor through a chip. The antenna is sequentially connected with an antenna matching network, an impedance line and an antenna debugging device connected with the rear end of the signal processor. According to the method, the signal processor is disconnected, the signal is guided from the front end of the signal processor by means of the signal test device after the signal is outputted by the chip, transduction debugging is carried out, and the antenna debugging device carries out antenna debugging at the rear end of the signal processor. According to the method for debugging the signal transduction and the antenna, the impedance line is taken to be matched with the antenna to coordinate the debugging of the signal transduction and the antenna, influences of the impedance line are included, and the influences of the impedance line on the signal transduction and the antenna are avoided.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a method for signal conduction and antenna debugging. Background technique [0002] With the development of mobile phones, the requirements for the omnidirectional radiation performance of mobile phones are getting higher and higher. The radiation performance of BLUETOOTH, WIFI, GPS, FM, etc., which were not required before, now have corresponding standards; The smaller and thinner the antenna, coupled with the influence of various metal parts, the antenna environment is getting worse and worse. In addition, due to the limitation of the mobile phone board type, in some cases, the impedance line has to be lengthened, or the impedance line can only go through the inner layer of the mobile phone PCB board, etc. These conditions seriously deteriorate the signal conduction performance, making BLUETOOTH / The WIFI signal cannot be effectively transmitted to the antenna after pa...
