Abstract

UN SEPARADOR DE REACTANCIA (218) MANTIENE UNA FRECUENCIA RESONANTE SUSTANCIALMENTE CONSTANTE PARA UNA ANTENA DE CUADRO DE TAMAÑO AJUSTABLE (200) QUE TIENE UN PRIMER (202) Y UN SEGUNDO (204) SEGMENTOS DE ANTENA. CADA SEGMENTO TIENE PRIMEROS (206, 208) Y SEGUNDOS (212, 214) EXTREMOS, ESTANDO LOS PRIMEROS EXTREMOS (206, 208) ACOPLADOS A UN RECEPTOR Y LOS SEGUNDOS EXTREMOS (212, 214) PROPORCIONAN UN AJUSTE DE TAMAÑO DEL CUADRO. EL SEPARADOR DE REACTANCIA (218) CONSTA DE UNA ENTRADA DEL SEPARADOR DE REACTANCIA (206) ACEPTADA AL SEGUNDO EXTREMO DEL PRIMER (202) SEGMENTO DE ANTENA. HAY VARIAS DERIVACIONES (T1-T7) COLOCADAS LINEALMENTE A LO LARGO DE UNA ESTRUCTURA INTEGRADA, PRESENTANDO LA ESTRUCTURA UNA SUPERFICIE SUSTANCIALMENTE PLANA Y QUE TIENE UNA LONGITUD PREDETERMINADA ENTRE LAS DERIVACIONES MAS EXTERIORES QUE CORRESPONDEN AL AJUSTE DEL TAMAÑO DE LA ANTENA DE CUADRO REQUERIDO. LAS DERIVACIONES (T1, T7) PROPORCIONAN UNAS SALIDAS DEL SEPARADOR DE REACTANCIA QUE SE PUEDEN SELECCIONAR PARA ACOPLARLAS AL SEGUNDO EXTREMO DEL SEGUNDO (204) SEGMENTO DE ANTENA. HAY VARIOS ELEMENTOS DE REACTANCIA (302, ..., 320) QUE ACOPLAN LA ENTRADA DEL SEPARADOR DE REACTANCIA (206) A CADA UNA DE LAS DISTINTAS DERIVACIONES (T1-T7) Y PROPORCIONAN UNA REACTANCIA SUSTANCIALMENTE CONTINUA MEDIA ENTRE LA ENTRADA DEL SEPARADOR DE REACTANCIA (206) Y CADA UNA DE LAS DISTINTAS DERIVACIONES (T1-T7).
