An antenna is provided for acquiring RF signals from various satellite ranging systems including GPS, GLONASS, GALILEO and OmniSTAR~. The antenna configuration includes a radiating structure of multi-arm spiral slots terminated with fractal loops. A leaky wave microstrip spiral feed network is used to excite the radiating structure of the antenna. The fixed beam phased array of aperture coupled slots is optimized to receive a right hand polarized signal. The proposed antenna is made out of a single PCB board. The antenna has a very uniform phase and amplitude pattern in the azimuth plane from 1.15 to 1.65 GHz, therefore providing consistent performance at GPS, GLONASS, GALILEO and OmniSTAR~ frequencies. The antenna also has a common phase center at the various frequencies from 1175 MHz to 1610 MHz and substantially the same radiation pattern and axial ratio characteristics.
L'invention concerne une antenne destinée à l'acquisition de signaux RF de divers systèmes de mesure de distance de satellites comportant GPS, GLONASS, GALILEO et OmniSTAR®. La configuration de l'antenne comporte une structure de rayonnement de fentes en spirale multi-bras et terminées par des boucles fractales. On utilise un réseau d'alimentation en spirale micro à ligne microruban à ondes de fuite pour exciter la structure de rayonnement de l'antenne. Le réseau à commande de phase fixe de fentes couplées par un orifice est optimisé pour recevoir un signal polarisé à droite. L'antenne selon l'invention est constituée d'une seule carte PCB. L'antenne a un motif de phase et d'amplitude très uniforme dans le plan azimutal de 1.15 à 1.65 GHz, ce qui offre une performance consistante des fréquences GPS, GLONASS, GALILEO et OmniSTAR® . Cette antenne a également un centre de phase commun à différentes fréquences de 1175 MHz à 1610 MHz et sensiblement le même motif de rayonnement et les mêmes caractéristiques de rapport axiale.
