Abstract (en)
The antenna system is made of identical radiating structures. Each structure is connected to a feed impedance adaptor. A processor (15) with control logic (Cm) is adapted to match to the master radiating structure and a logic structure (Cs) transfers the matching parameter to the slave radiating structure.
Abstract (fr)
Système antennaire composé de (N+1) structures rayonnantes sensiblement identiques avec N supérieur ou égal à 1, lesdites (N+1) structures étant disposées parallèlement les unes aux autres et chaque structure rayonnante est reliée à un dispositif d'alimentation et d'adaptation d'impédance. Utilisation pour des gammes de fréquences comprises entre 1.5 à 30 MHz. <IMAGE>
