Cet article présente la formulation pour l'évaluation du couplage externe dans l'antenne réseau de guides d'ondes à fente monocouche à alimentation en phase alternée avec déflecteurs en utilisant la méthode du spectre de solutions bidimensionnelles (S2DS). Un réseau de fentes unidimensionnelles est extrait du réseau en supposant la périodicité dans la direction transversale et en introduisant les conducteurs électriques parfaits dans la région externe. L'excitation uniforme sur le réseau fini est synthétisée de manière itérative pour démontrer les résultats rapides et précis obtenus par S2DS. Un modèle de conception unitaire avec les chicanes est introduit pour déterminer les paramètres initiaux de la paire de fentes qui accélèrent l'itération. L'expérience à 25.3 GHz démontre une bonne uniformité de la distribution du champ d'ouverture ainsi que des effets des chicanes. La directivité est de 32.7 dB ce qui correspond à une efficacité d'ouverture de 90.5% et la réflexion est inférieure à -15.0 dB sur 1.3 GHz.

Abstract: This paper presents the formulation for the evaluation of external coupling in the alternating-phase feed single-layer slotted waveguide array antenna with baffles by using the Spectrum of Two-Dimensional Solutions (S2DS) method. A one-dimensional slot array is extracted from the array by assuming the periodicity in transversal direction and introducing the perfect electric conductors in the external region. The uniform excitation over the finite array is synthesized iteratively to demonstrate the fast and accurate results by S2DS. A unit design model with the baffles is introduced to determine the initial parameters of the slot pair which accelerate the iteration. Experiment at 25.3 GHz demonstrates good uniformity of the aperture field distribution as well as the effects of the baffles. The directivity is 32.7 dB which corresponds to the aperture efficiency 90.5% and the reflection is below -15.0 dB over 1.3 GHz.
