Cet article propose un sous-réseau de guides d'ondes à extrémité ouverte à double polarisation linéaire conçu pour être utilisé dans les antennes réseau à commande de phase. Le sous-réseau proposé est un réseau linéaire unidimensionnel composé d'éléments d'antenne à guide d'ondes à extrémités ouvertes et de réseaux d'alimentation de lignes suspendues pour réaliser des polarisations verticales et horizontales. L'antenne comprend une nouvelle transition de ligne à bande suspendue à guide d'ondes qui combine des guides d'ondes à double et quadruple crête pour minimiser la taille de la transition et améliorer l'isolation du port. Des poteaux métalliques sont installés sur les ouvertures du guide d'ondes pour éliminer l'aveuglement du balayage. Des sous-réseaux prototypes sont fabriqués et testés dans un réseau de 16 sous-réseaux. Les tests expérimentaux et les simulations numériques indiquent que le sous-réseau prototype offre un faible coefficient de réflexion inférieur à -11.4 dB, une faible polarisation croisée inférieure à -26 dB et une efficacité d'antenne supérieure à 69 % dans la bande passante de fréquence de 14 %.

Abstract: This paper proposes a dual linear-polarized open-ended waveguide subarray designed for use in phased array antennas. The proposed subarray is a one-dimensional linear array that consists of open-ended waveguide antenna elements and suspended stripline feed networks to realize vertical and horizontal polarizations. The antenna includes a novel suspended stripline-to-waveguide transition that combines double- and quad-ridge waveguides to minimize the size of the transition and enhance the port isolation. Metal posts are installed on the waveguide apertures to eliminate scan-blindness. Prototype subarrays are fabricated and tested in an array of 16 subarrays. The experimental tests and numerical simulations indicate that the prototype subarray offers a low reflection coefficient of less than -11.4dB, low cross-polarization of less than -26dB, and antenna efficiency above 69% in the frequency bandwidth of 14%.
