Abstract

UN SISTEMA DE ANTENA PARA SUMINISTRAR RADIACION POR SUSTANCIALMENTE LOS 360 (GRADOS) EN ACIMUT MEDIANTE LA ILUMINACION DE UN RECEPTOR CONICO CON UN HAZ DE RADIACIONES QUE TIENE UNA DISTRIBUCION DE FRECUENCIAS CON UN MINIMO LOCAL QUE ES COINCIDENTE CON EL PUNTO DEL REFLECTOR, EVITANDOSE DE DICHA FORMA LA DISPERSION. PREFERENTEMENTE, LA DISTRIBUCION DE LA INTENSIDAD DE LA RADIACION ES ANULAR Y MAS PREFERENTEMENTE DE TIPO LAGUERREGAUSS.
