Abstract
A tuned antenna resonant circuit substantially increases the range of a passive transponder in a high-frequency electromagnetic carrier field, in that the real and imaginary parts of the impedance associated with the contact surface of the antenna contact are minimized and the energy absorbed from the carrier field by a serial resonant circuit is used to the greatest possible extent for generating the supply voltage for the integrated circuit of the transponder.
