Method and system for mobile phone antenna coupling test on production line

The invention discloses a method and a system for mobile phone antenna coupling test on a production line. The system comprises a coupling test module, an industrial personal computer, a multi-signal-source device, radio-frequency cables, a combiner and a coupling shielding box. The coupling test module comprises mobile internal test software for coupling test of a to-be-tested mobile phone in set process; the industrial personal computer is connected with the multi-signal-source device and used for configuration of parameters of the multi-signal-source device and controlling a transmission channel of the multi-signal-source device to open or close; the multi-signal-source device under control of the industrial personal computer is used for generating radio-frequency signals with multiple frequency points for mobile phone antenna coupling; the radio-frequency cable is arranged between the multi-signal-source device and the combiner and between the combiner and the coupling shielding box respectively; the coupling shielding box is used for placement of at least one mobile phone and used for broadcast type parallel coupling test of mobile phones. The method and the system for mobile phone antenna coupling test on a production line have the advantage that test efficiency and precision can be improved.
