Abstract

ANTENA MULTIHAZ CAPAZ DE RECIBIR/TRANSMITIR SEÑALES A LA MISM A FRECUENCIA, EN UNA O MAS DIRECCIONES, SIMULTANEAMENTE, QUE CONSISTE ESENCIALMENTE EN UNO O MAS ELEMENTOS RADICANTES (2), DE UN REFLECTOR PARABOLICO (1) CON UN BORDE DE FORMA CUADRADA (39 QUE ES UNO DE CUATRO VERTICES (4) DEL CUADRADO QUE CIRCUNSCRIBE EL REFLECTOR (1) SITUADO CERCA DEL EJE FOCAL DEL PARABOLOIDE. LOS ELEMENTOS RADIANTES (2) Y CORRESPONDIENTEMENTE, LAS DIRECCIONES OPERATIVAS, ESTAN ALINEADOS A LO LARGO DE UNO DE LOS DOS PLANOS ORTOGONALES POSIBLES. LA INVENCION SE REFIERE, RESPECTO DE SOLUCIONES PREVIAS A: UN AISLAMIENTO MAXIMO ENTRE LAS DIRECCIONES OPERATIVAS, EN LA MISMA GANANCIA DE ANTENA; DIMENSION MIMINA DE LA SUPERFICIE REFLECTANTE YA QUE LA FORMA RECTANGULAR REDUCE LAS DIMENSIONES GLOBALES Y FORMA PAQUETES MAS FACILMENTE - Y POR CONSIGUIENTE SU TRANSPORTE. CAMPO TECNICO-CIENTIFICO: ELECTRONICA DE ANTENA ESPACIAL Y NO ESPACIAL; CAMPO DE APLICACION: ANTENAS ESPACIALES A USAR ESPECIALMENTE PARA SEÑALES DE TV.
