Abstract

LA INVENCION SE REFIERE A LOS TERMINALES CONOCIDOS, LOS CUALES SON CAPACES DE RECIBIR Y DEMODULAR LAS SEÑALES MEDIANTE LA MISMA ANTENA Y EL MISMO DIODO, ASI COMO PUEDEN MODULAR Y TRANSMITIR LAS SEÑALES, DICHOS TERMINALES TIENEN A MENUDO UNA EFICIENCIA POBRE, PARTICULARMENTE SI LA ANTENA SE IMPLEMENTA CON LA FORMA DE UNA PLACA PLANA. ACOPLANDO UN PRIMER TERMINAL DE ALTA RESISTENCIA DE LA ANTENA AL DIODO, Y ACOPLANDO UN SEGUNDO TERMINAL DE BAJA RESISTENCIA A TIERRA POR MEDIO DE UN ELEMENTO INDUCTIVO, SE OBTIENE UN TERMINAL CON UNA BUENA EFICIENCIA, RESPECTO A LA RECEPCION Y A LA DEMODULACION DE LAS SEÑALES Y RESPECTO A LA MODULACION Y A LA TRANSMISION DE LAS SEÑALES A LA VEZ.
