Matrizes de slots de guia de onda pós-parede são candidatas potenciais para sistemas de ondas milimétricas. A modelagem das pós-paredes pelas paredes sólidas equivalentes em termos de comprimento de onda guiado é indispensável para otimização intensiva do projeto de slots para redução da carga computacional. Nas matrizes de ranhuras de guia de ondas de modo único, os erros de modelagem do guia de ondas pós-parede pelo guia de ondas de parede sólida são sérios, especialmente para as ranhuras localizadas transversalmente. Os erros de previsão do parâmetro S tornam-se maiores à medida que aumentamos a altura do guia de ondas para utilizar a vantagem de baixa perda do guia de ondas. Os autores propõem uma nova estrutura de guia de ondas pós-parede, denominada pós-parede conectada (C-PW), para aumentar a equivalência. O guia de ondas C-PW mantém uma equivalência aprimorada com as paredes sólidas, mesmo para uma altura de substrato maior. As previsões são confirmadas por simulações e medições. Uma matriz linear de 8 elementos de pares de slots com cancelamento de reflexão é projetada usando o modelo de parede sólida equivalente para demonstrar a viabilidade do projeto simples no C-PW.

Abstract: Post-wall waveguide slot arrays are potential candidates for millimeter-wave systems. The modeling of the post-walls by the equivalent solid-walls in terms of guided wavelength is indispensable for intensive optimization of slot design for reducing computational load. In the single mode waveguide slot arrays, the modeling errors of the post-wall waveguide by the solid-wall waveguide are serious especially for the transversely located slots. The S-parameter prediction errors become larger as we increase the height of the waveguide to utilize the low-loss advantage of the waveguide. The authors propose a novel post-wall waveguide structure, named as a connected post-wall (C-PW), to enhance the equivalence. The C-PW waveguide keeps enhanced equivalence to the solid-walls even for a larger substrate height. The predictions are confirmed by simulations and measurements. An 8-element linear array of reflection-cancelling slot pairs is designed by using the equivalent solid-wall model to demonstrate the feasibility of the simple design in the C-PW.
