摘要：The invention relates to a system and method for testing radio-frequency tags(18). The system comprises a reading zone (17) for a radio-frequency tag and at least twoelectrodes (11A,11B) for capacitively coupling to the tag placed in the reading zone.According to the invention, the system further comprises a communication terminal (14)connected to each of the at least two electrodes for feeding signals to the electrodesand for reading tag response signals from the electrodes, and a hybrid coupler (13) forcausing a phase difference between the excitation signals fed to the at least twoelectrodes from the communication terminal and for combining the response signalsfrom the at least two electrodes at the communication terminal (14). The inventionallows for efficient coupling to tags in near field and relieves the tag positioningrequirements during testing.
