Cet article propose une antenne à polarisation circulaire bi-bande à double boucle rectangulaire pour les systèmes mondiaux de navigation par satellite (GNSS). L'antenne proposée combine deux grandes boucles rectangulaires extérieures avec deux petites boucles intérieures. Chaque grande boucle extérieure est reliée à sa petite boucle rectangulaire intérieure correspondante. Chaque boucle présente des espaces situés symétriquement par rapport à un point d'alimentation pour produire une polarisation circulaire à droite (RHCP). La position de l'espace et la forme des boucles rectangulaires sont très importantes pour ajuster à la fois les caractéristiques d'adaptation d'impédance et de polarisation circulaire. L'antenne proposée offre des caractéristiques de fréquence à double bande de rapport d'onde stationnaire de tension (VSWR) et de rapport axial (AR) qui incluent les bandes L1 (1575.42 2 MHz) et L1227.60 (8.7 XNUMX MHz). Les gains d'antenne dépassent XNUMX dBi. De larges modèles d'élévation AR sont obtenus. Ces caractéristiques d'antenne sont bien adaptées à un positionnement précis.

Abstract: This paper proposes a dual-band dual-rectangular-loop circular polarization antenna for Global Navigation Satellite Systems (GNSSs). The proposed antenna combines two large outer rectangular loops with two small inner loops. Each large outer loop is connected to its corresponding small inner rectangular loop. Each loop has gaps located symmetrically with respect to a feed point to produce Right Handed Circular Polarization (RHCP). The gap position and the shape of the rectangular loops are very important to adjust both the impedance matching and circular polarization characteristics. The proposed antenna offers dual-band Voltage Standing Wave Ratio (VSWR) and Axial Ratio (AR) frequency characteristics that include the L1 (1575.42 MHz) and L2 (1227.60 MHz) bands. The antenna gains exceed 8.7 dBi. Broad AR elevation patterns are obtained. These antenna characteristics are well suited to precise positioning.
