Pour obtenir une faible composante de polarisation croisée en plus d'un motif de couverture circulaire dans une structure compacte, cet article propose un nouveau cornet multimode avec une configuration arbitraire d'ondulation coaxiale qui joue deux rôles de convertisseurs de mode et de selfs. Le cornet proposé peut être conçu par itération d'une procédure d'optimisation non linéaire basée sur des matrices de diffusion généralisées pré-calculées par la technique d'appariement de modes. Nous montrons un cornet compact avec quatre ondulations coaxiales pour façonner un faisceau à couverture circulaire sur une plage de fréquences de bande passante de 20 %. L'efficacité du cornet conçu est discutée en évaluant numériquement et expérimentalement le VSWR et les caractéristiques de rayonnement en bande X.

Abstract: For achieving low cross-polarization component in addition to circular-coverage pattern in compact structure, this paper proposes a novel multimode horn with arbitrary coaxial-corrugation configuration which plays two roles of mode converters and chokes. The proposed horn can be designed by iteration of non-linear optimization procedure based on generalized scattering matrices pre-calculated by the mode-matching technique. We show a compact horn with four coaxial corrugations for shaping circular-coverage beam over frequency range of bandwidth 20%. The effectiveness of the designed horn is discussed by evaluating VSWR and radiation characteristics in X-band numerically and experimentally.
