Un nouveau modèle d'analyse des jonctions en T des guides d'ondes post-mur est proposé. Les parois solides équivalentes pour les montants-murs devant avoir une longueur d'onde guidée égale sont corrigées dans le modèle d'analyse de sorte que l'épaisseur de paroi pour les fenêtres de couplage soit réglée sur la différence de largeur entre le montant-mur et les guides d'ondes à paroi solide. La précision du modèle proposé est confirmée en le comparant à une analyse HFSS de la structure réelle de la jonction en T du guide d'ondes post-mur, y compris les surfaces des poteaux. Des antennes modèles 61.25 GHz sont fabriquées pour une vérification expérimentale. La réflexion de l'antenne conçue par le modèle d'analyse modifié est supprimée en dessous de -15 dB sur une bande passante de 5.6 GHz, tandis que celle de l'antenne conçue par le modèle conventionnel est supérieure à -15 dB autour de la fréquence de conception.

Abstract: A novel analysis model for post-wall waveguide T-junctions is proposed. Equivalent solid-walls for the post-walls to have equal guided wavelength are corrected in the analysis model so that the wall thickness for the coupling windows is set to the difference in the width between the post-wall and the solid-wall waveguides. The accuracy of the proposed model is confirmed by comparing it to an HFSS analysis for the real structure of the post-wall waveguide T-junction including the post surfaces. 61.25 GHz model antennas are fabricated for experimental verification. The reflection of the antenna designed by the modified analysis model is suppressed to below -15 dB over a 5.6 GHz bandwidth, while that in the antenna designed by the conventional model is larger than -15 dB around the design frequency.
