Abstract

Mejoras en sistemas de antena que comprenden un miembro o elemento que dispone de una superficie a la que ha sido practicada una abertura, medios para la transferencia de energía acoplados en puntos colocados sobre porciones de los bordes opuestos de la abertura para establecer una serie de máximas de corriente espaciados en dicha superficie y medios para disponer de impedancia en la presencia de máximos de corriente en ciertas áreas del miembro o elemento citado.
