Surface acoustic wave converter and identification system using the same

摘要

A tag card structure allows electrodes in a dispersive transducer (9) with a positive electrode aerial part (31) and a negative electrode aerial part (32) to connect to common bus wires in non-dispersive transducers (16). A transducer device reacts to an electromagnetic chirp signal (14) as an input signal with a pulse train (40) with a logical binary order of '10110011'.
