Abstract
A method for contact-free testing of antennas applied to a material web, wherein the material web having the antennas is passed to a measurement device. The antennas are passed past an assigned measurement antenna arrangement of the measurement device in the region of the measurement device and the measurement antenna arrangement has a high-frequency signal Sof a transmitter applied to it. This signal is correlated with a pre-determined working frequency fof the antennas. The high-frequency signal Sthat returns from the measurement antenna arrangement is determined and compared with default values, and the adherence to production tolerances is determined by the comparison of the returning high-frequency signal Swith the default values for each of the individual antennas.
