Abstract

Un sistema de Antena Directiva que comprende el conjunto de una diversidad de elementos radiadores para producir un diagrama de radiación, dispositivos de pantalla, substancialmente de una longitud igual a media longitud de onda de la frecuencia a que trabaja la antena en la dirección de polarización, dispuestos para ser ajustados en posición adyacente a ciertos de dichos elementos radiantes y por medio de los cuales los efectos de directividad de dichos elementos radiantes sobre el diagrama de radiación, pueden ser substancialmente eleminados.
