A transponder is disclosed to receive a wireless electromagnetic query signal and transmit a corresponding wireless electromagnetic response signal. The transponder comprises a first coil and at least one further coil that function as antennas to receive the wireless electromagnetic query signal and generate separate wired electrical incoming signals. An axis of the first coil and an axis of the at least one further coil are differently aligned in space, and each coil is associated with at least one means for limiting the voltage of the respective incoming signal. The separate wired electrical incoming signals are rectified and converted to current signals. The peak values of the current signals are detected and compared, such that a control signal is generated to identify one coil between the first coil and the at least one further coil that has a larger peak value of current.
