  • Abstract
    A use of self-matched unidirectional transducers (SMUDTs) is proposed in application to SAW tags. SMUDT provides simultaneously both high degree of its directionality and matching with the tag antenna without additional external circuitry. Numerical simulations of the tags, synthesized on 128° YX-LiNbO3, confirm an efficiency of the proposed technique.
