Abstract
ANTENA DE DOS POLARIZACIONES. ANTENA DE DOS POLARIZACIONES, LINEALES Y/O CIRCULARES, EN BANDEJA METALICA REFLECTORA, CUBIERTA CON UN RADOMO DIELECTRICO Y CON TAPAS EXTREMAS, CON ELEMENTOS RADIANTES ALIMENTADOS POR UNAS LINEAS, EN DOS REDES INDEPENDIENTES SEGUN POLARIZACION, DE FORMA QUE CADA LINEA SE CONECTA A LA CAJA DE DISTRIBUCION Y MODIFICANDO LA FORMA Y TAMAÑO DE LAS LINEAS Y LA POSICION DEL PUNTO DE ALIMENTACION DE LOS DISCOS PRINCIPALES DE LOS ELEMENTOS RADIANTES, SE OBTIENE UN ANGULO DE RADIACION, VERTICAL Y HORIZONTAL, DE 45 Y 135 , O BIEN CIRCULAR A DERECHAS E IZQUIERDAS. FIGURA 1.
