Title
(EN) Low Profile Multi Band Antenna System
(FR) SYSTÈME D'ANTENNE MULTIBANDE À PROFIL BAS
Abstract
(EN)
A multi band antenna system for transmission and reception of electromagnetic signals in a low-profile dual reflector configuration with position- controlled main-reflector, and fixed sub-reflector and feed horn. An added linear slide of the main-reflector with respect to the sub-reflector synchronized with variable tilt angle of the main-reflector for compensation for the varied focal length in the main- reflector to the beam due the varied main-reflector tilt. The system achieves a beam elevation of 10⁰ to 100⁰ (full elevation), minimum gain variations over the full elevation travel, swept volume as per ARINC 791 (e.g. Boeing Radome or Airbus Radome), and can be used to meet wide-Tx/Rx bands requirements.

L'invention concerne un système d'antenne multibande pour la transmission et la réception de signaux électromagnétiques dans une configuration de double réflecteur à profil bas avec un réflecteur principal à position commandée, et un sous-réflecteur fixe et un cornet d'alimentation. Une lame linéaire ajoutée du réflecteur principal par rapport au sous-réflecteur est synchronisée avec un angle d'inclinaison variable du réflecteur principal pour compenser la longueur focale variable dans le réflecteur principal jusqu'au faisceau en raison de l'inclinaison du réflecteur principal variable. Le système atteint une élévation de faisceau de 10° à 100° (élévation complète), des variations de gain minimales sur le trajet d'élévation complet, balayé selon la norme ARINC 791 (par exemple un radôme Boeing ou un radôme Airbus), et peut être utilisé pour satisfaire des exigences de bande large Tx/Rx.
