Abstract

Chaque antenne à onde de sol du réseau comprend un plan de masse (PM1, PM2) enfoui sensiblement horizontalement à proximité et sous la surface du sol (S) et une ligne d'excitation métallique (LE1, LE2) s'étendant sensiblement rectilignement et parallèlement au-dessus du plan de masse et à au moins à 1 m environ du sol pour rayonner des ondes de sol hectométriques ou kilométriques. Le réseau comprend au moins un moyen d'interconnexion (LR) reliant des première et deuxième antennes consécutives du réseau pour alimenter la deuxième antenne avec une puissance non rayonnée par la première antenne représentant environ 90% de la puissance fournie à la première antenne. Chaque antenne est adaptée à son impédance caractéristique pour rayonner des ondes progressives. Une ligne de retour souterraine inverseuse de phase (LR) peut remettre en phase les ondes propagées par deux antennes consécutives.
