Une nouvelle technique de conception pour les réseaux de fentes de guides d'ondes bidimensionnels (2D) est proposée dans cet article, combinant une méthode d'analyse des moments (MoM) pleine onde et un circuit équivalent avec la contrainte explicite de l'adaptation d'entrée. L'admittance et l'espacement des fentes sont déterminés d'abord dans un circuit équivalent pour réaliser la distribution souhaitée de dissipation de puissance et de phase, avec la restriction explicite de l'adaptation d'entrée. Deuxièmement, en appliquant une analyse MoM pleine onde au réseau 2D fini, les paramètres des fentes sont déterminés de manière itérative pour réaliser l'admittance active conçue ci-dessus, où le couplage mutuel des fentes et l'épaisseur de la paroi sont pleinement pris en compte. L'admittance, traitée comme paramètre clé dans le circuit équivalent, correspond à la puissance dissipée des fentes mais pas à la tension des fentes, qui est directement synthétisée à partir du diagramme de rayonnement. La valeur initiale de la dissipation de puissance est supposée proportionnelle au carré de l’amplitude de la tension d’encoche souhaitée. Cette hypothèse conduit à une procédure de rétroaction, car la distribution de tension des fentes résultante diffère généralement de celle souhaitée en raison de l'effet de non-uniformité de l'impédance caractéristique sur les ouvertures des fentes. Cette erreur de tension de fente est utilisée pour renouveler la répartition initiale de la puissance dissipée dans le circuit équivalent. Généralement, un seul cycle de rétroaction est nécessaire.

Abstract: A novel design technique for two-dimensional (2-D) waveguide slot arrays is proposed in this paper that combines a full-wave method of moments (MoM) analysis and an equivalent circuit with the explicit restraint of input matching. The admittance and slot spacing are determined first in an equivalent circuit to realize the desired distribution of power dissipation and phase, with the explicit restraint of input matching. Secondly by applying a full-wave MoM analysis to the finite 2-D array, slot parameters are iteratively determined to realize the active admittance designed above where slot mutual coupling and wall thickness are fully taken into account. The admittance, treated as the key parameter in the equivalent circuit corresponds to the power dissipation of the slots but not to the slot voltage, which is directly synthesized from the radiation pattern. The initial value of the power dissipation is assumed to be proportional to the square of the amplitude of the desired slot voltage. This assumption leads to a feedback procedure, because the resultant slot voltage distribution generally differs from the desired ones due to the effect of non-uniformity in the characteristic impedance on slot apertures. This slot voltage error is used to renew the initial distribution of power dissipation in the equivalent circuit. Generally, only one feedback cycle is needed. Two 24
