Definitions

  • One exemplary embodiment is a micro-strip planar antenna in printed technology with radiating patch elements.
  • every radiating element would have to be made so as to be adapted to operate over the whole band.
  • the radiating elements are narrow-band elements, for which reason it thus becomes necessary to make two separate antenna modules, one arranged for operating in reception in a first range of frequencies, and one arranged for operating in transmission in a second range of frequencies.
  • the micro-strip distribution network comprises a ground plane 100, a dielectric substrate 110 and conductive tracks 120 arranged according to a predetermined branched configuration for the feeding to a set of radiating elements (12T, 12R) of an antenna module according to a predetermined phase shifting of the signals.
  • the slot extends according to a direction angularly misaligned with the discontinuities in shape (bevelled corners, peripheral incisions) of the areas forming the radiating elements, and therefore the radiating elements are asymmetrically shaped with respect to a median axis thereof, coinciding with the direction of the slot extension (or, in equivalent words, with the direction of extension of the section of micro-strip feeding line associated with it), so as to emit electromagnetic radiation according to a circular polarization.

Abstract

L'invention porte sur une antenne en réseau plan en microruban, présentant une surface de rayonnement (S) comprenant des premiers éléments rayonnants (12T) agencés pour fonctionner en émission et des seconds éléments rayonnants (12R) agencés pour fonctionner en réception, ainsi qu'un réseau d'alimentation de signal agencé sur un plan parallèle à la surface de rayonnement (S), comprenant des lignes microrubans (120) couplées de façon capacitive aux éléments mentionnés ci-dessus (12R, 12T). Les premiers et seconds éléments rayonnants (12R, 12T) sont réalisés sur une même surface de rayonnement (S) de l'antenne, selon une configuration intercalée, et sont aptes à fonctionner à des plages de fréquences différentes et à des polarisations perpendiculaires.
