Abstract

Mejoras en dispositivos de acoplamiento entre antenas y lineas de transmisión caracterizados por un transformador eléctrico empleado para acoplar dos circuitos de diferentes impedancias en una banda de altas frecuencias llevando una serie de conductores eléctricos dispuestos en dos grupos los medios para conectar todos estos conductores unidos en un extremo de forma tal que forman los dos grupos de conductores lineas de transmisión en cortocircuito en dicho extremo y abiertas por el otro y de tal longitud que resuenen en cuarto de onda en una frecuencia de la banda medios para conectar uno de dichos circuitos a los conductores en uno de los grupos y medios para conectar el otro circuito a todos los conductores del extremo cortocircuitado.
