Abstract

SE DESCRIBE UN APARATO PARA ACOPLAR ENERGIA ELECTRICA DENTRO Y/O FUERA DE UN DISPOSITIVO DE ONDA ACUSTICA DE SUPERFICIE (SAW), TAL COMO UN CONTESTADOR. EL DISPOSITIVO SAW (10) TIENE UN SUSTRATO PIEZOELECTRICO (12) CON UNA SUPERFICIE EXPUESTA; AL MENOS UN TRANSDUCTOR SAW (14), DISPUESTO EN LA SUPERFICIE DEL SUSTRATO, PARA LA CONVERSION ENTRE ENERGIA ELECTRICA Y ENERGIA SAW; Y UN CIRCUITO CONDUCTOR (22) DISPUESTO EN LA SUPERFICIE DE DICHO SUSTRATO Y CONECTADO ELECTRICAMENTE A DICHO TRANSDUCTOR. EL CIRCUITO CONDUCTOR FORMA UN ELEMENTO INDUCTOR PARA ACOPLAR ENERGIA DENTRO Y/O FUERA DEL DISPOSITIVO SAW. UN PRIMER CIRCUITO INDUCTOR, FORMADO POR AL MENOS UNA VUELTA PARCIAL DE UN CONDUCTOR ELECTRICO, ESTA ACOPLADO DE FORMA INDUCTIVA AL CIRCUITO CONDUCTOR DE LA SUPERFICIE DEL SUSTRATO. EL DISPOSITIVO PARA TRANSMITIR Y/O RECIBIR UNA SEÑAL ELECTRICA HACIA Y/O DESDE DICHO DISPOSITIVO SAW INCORPORA UN SEGUNDO CIRCUITO INDUCTOR QUE ESTA ACOPLADO DE FORMA INDUCTIVA A DICHO PRIMER CIRCUITO INDUCTOR. DE ESTA MANERA EL PRIMER CIRCUITO INDUCTOR FORMA UNA TRAYECTORIA DE ACOPLAMIENTO INDUCTOR INTERMEDIA (38) ENTRE EL SEGUNDO CIRCUITO INDUCTOR DEL DISPOSITIVO TRANSMISOR RECEPTOR Y EL CIRCUITO CONDUCTOR EN LA SUPERFICIE DEL SUSTRATO.
