Les antennes à fentes à ligne radiale (RLSA) à ouverture extrêmement petite sont analysées par la méthode des moments. Dans un premier temps, le modèle d'analyse d'un guide d'ondes cylindrique en termes de modes de cavité rectangulaires est confirmé pour un RLSA avec une disposition de fentes en spirale. Le VSWR global ainsi que la symétrie de rotation de la structure réelle des RLSA sont prédits pour la première fois et confirmés expérimentalement. Deuxièmement, le diamètre minimum du réseau concentrique RLSA est estimé pour lequel le modèle d'analyse conventionnel d'un guide d'ondes rectangulaire est valable pour la conception de paires de fentes correspondantes à la périphérie court-circuitée du guide d'ondes radial. Il s'avère que la courbure et la paroi courte cylindrique à la périphérie de l'ouverture doivent être prises en compte dans la conception et l'analyse de petits RLSA avec un gain inférieur à environ 25 dBi.

Abstract: Extremely small aperture radial line slot antennas (RLSAs) are analyzed by method of moments. At first, the analysis model of cylindrical waveguide in terms of rectangular cavity modes is confirmed for a RLSA with a spiral slot arrangement. The overall VSWR as well as rotational symmetry of the actual structure of RLSAs is predicted for the first time and is confirmed experimentally. Secondly, the minimum diameter of the concentric array RLSA is estimated for which the conventional analysis model of a rectangular waveguide is valid for the design of matching slot pairs at the shorted periphery of the radial waveguide. It is found that the curvature and cylindrical short wall at aperture periphery must be considered in the design and analysis of small RLSAs with the gain lower than about 25 dBi.
