Abstract

1. Antena emisora de baja frecuencia, que incluye: - un núcleo magnético alargado (10) que tiene una primera parte extrema (11) y una segunda parte extrema (12), opuestas entre sí, y una parte central (13) entre las mismas, definiendo dicho núcleo magnético alargado (10) un eje longitudinal (A) que se extiende a través de dicha primera parte extrema (11), parte central (13) y segunda parte extrema (12), y - una bobina (20) hecha de un hilo conductor eléctrico que rodea al menos parte del núcleo magnético alargado (10) arrollada alrededor de dicho eje longitudinal (A); en la que el núcleo magnético alargado (10) tiene una sección transversal, perpendicular al eje longitudinal (A), decreciente desde la primera parte extrema (11) hacia dicha parte central (13) y desde la segunda parte extrema (12) hacia dicha parte central (13) del núcleo magnético alargado (10), de manera que el flujo magnético se concentra en la parte central (13) produciendo así un rango de transmisión mejorado; caracterizada por qué - el núcleo magnético alargado (10) es simétrico en relación con el eje longitudinal (A); y - la primera parte extrema (11) y la segunda parte extrema (12) tienen unas caras extremas convexas (14).
