Abstract

The invention belongs to the field of coupling testing and provides a coupled antenna and a complete machine testing system. The coupled antenna comprises a dipole used for coupling radio-frequency signals of a preset frequency band, a feeder line and a coupling testing interface. The dipole comprises two symmetric antenna elements and one of the symmetric antenna elements is grounded; one end of the feeder line is connected to a connecting point on the symmetric axis of the dipole and used for transmitting the radio-frequency signals received by coupling of the dipole to the coupling test interface; the coupling test interface is arranged at the other end of the feeder line and used for being externally connected with a gauge so as to accomplish whole machine testing. Thus, in the complete machine testing system, the coupled antenna is used for replacing a traditional coupling board and the coupling efficiency of the radio-frequency signals sent by the antenna of a coupling terminal device is improved, so that complete machine testing is accurately conducted through the radio-frequency signals coupled by the coupled antenna.

Description

technical field [0001] The invention belongs to the field of coupling testing, in particular to a coupling antenna and a complete machine testing system. Background technique [0002] For terminal equipment (including mobile phones, data cards, network cards, notebooks and other terminals using wireless communication technology), after the production and assembly are completed, it must be tested for the whole machine (Mobile Test, MT) to test the wireless performance. [0003] At present, the whole machine test system using the traditional coupling board, such as figure 1 As shown, the terminal device 6 is placed on the upper part of the plastic fixture 7 during the whole machine test, and the coupling plate 4 is located in the middle of the same plastic fixture 7, and a certain distance is formed between the terminal device 6 and the coupling plate 4; in order to prevent external interference, The plastic fixture 7 is placed in the shielding box 5; in addition, the couplin...
