FIELD: radio engineering, communication.
SUBSTANCE: passive anticollision radiofrequency identification label surface acoustic wave with a frequency-time code difference, characterized in that it comprises a topology comprising a reflective structure, the reflection coefficient which is determined by the corresponding frequency N-th pulse of the interrogation signal, which makes possible the separation and identification zone reader identification codes of several labels for the two information signs - the timing and frequency, thereby solving the conflict that has arisen between passive SAW tags.
EFFECT: separation of signals from multiple tags in the frequency domain, if in the time domain when reading transceiver antenna reader response signals from several pulses marks coincide, thereby solves the problem of collisions.
