Title
(EN) HELIX FEED BROADBAND ANTENNA HAVING REVERSE CENTER FEEDER
(FR) ANTENNE À LARGE BANDE À SOURCE HÉLICOÏDALE AYANT UNE SOURCE PRIMAIRE CENTRALE INVERSÉE
Abstract
(EN)
Provided is a helix feed broadband antenna having a reverse center feeder, which minimizes an antenna enclosure and a radio wave shadow area by using the reverse center feeder including a reflecting plate and a rear radiation pattern, thereby enhancing performance of an antenna. The helix feed broadband antenna having a reverse center feeder, including a reverse center feeder which radiates an antenna radiation pattern backward; and a reflecting plate which is positioned at a rear side of the reverse center feeder so as to receive and transmit radio wave by reflecting an antenna beam radiated from the reverse center feeder.

L'invention porte sur une antenne à large bande à source hélicoïdale ayant une source primaire centrale inversée, minimisant l'enveloppe d'antenne et la zone d'ombre des ondes radio à l'aide d'un dispositif de source primaire centrale inversée comprenant une plaque de réflexion et un configuration de rayonnement arrière, de façon à améliorer ainsi les performances de l'antenne. L'antenne à large bande à source hélicoïdale ayant une source primaire centrale inversée, comprend une source primaire centrale inversée rayonnant selon une configuration de rayonnement d'antenne vers l'arrière ; et une plaque de réflexion positionnée en un côté arrière de la source primaire centrale inversée de façon à recevoir et à émettre les ondes radio par réflexion du faisceau d'antenne rayonné par la source primaire centrale inversée.
