Dans cet article, nous présentons les effets des superstrats finis et des sols asymétriques sur les performances des antennes superstrats à gain élevé. Premièrement, lorsque la source d'une antenne superstrat est située sur un bord d'un plan de sol, c'est-à-dire un plan de sol asymétrique, le gain de l'antenne superstrat peut être amené à correspondre au gain de l'antenne superstrat avec un plan de sol symétrique en utilisant le PEC (E-plan asymétrique) ou le mur AMC (H-plan asymétrique) près du bord. Deuxièmement, le gain de l'antenne superstrate, qui a un plan de masse dont les dimensions sont suffisamment proches de l'infini, s'avère être à peu près proportionnel à l'ampleur de la réflexion d'une surface partiellement réfléchissante (PRS). Il s'avère que lorsque la taille du fond carré a une dimension finie de deux longueurs d'onde ou moins, l'amplitude de réflexion du PRS doit avoir la valeur optimale pour obtenir un gain maximum. Enfin, le gain de l'antenne superstrat est étudié lorsque le plan de sol diffère d'un PRS. Pour les trois cas ci-dessus, les performances de l'antenne superstrat sont vérifiées et comparées par analyse, simulation pleine onde et mesure.

Abstract: In this paper, we present the effects of finite superstrates and asymmetrical grounds on the performance of high gain superstrate antennas. First, when the source of a superstrate antenna is located at an edge of a ground plane, that is, an asymmetric ground plane, the gain of the superstrate antenna can be made to match the gain of the superstrate antenna with a symmetrical ground plane using the PEC (E-plane asymmetric) or the AMC wall (H-plane asymmetric) near the edge. Second, the gain of the superstrate antenna, which has a ground plane with dimensions sufficiently close to infinite, is found to be roughly proportional to the reflection magnitude of a partially reflective surface (PRS). It is found that when the square ground size has a finite dimension of two wavelengths or less, the reflection magnitude of the PRS should have the optimum value for achieving maximum gain. Finally, the gain of the superstrate antenna is studied when the ground plane differs from a PRS. For the above three cases, the performances of the superstrate antenna are verified and compared by analysis, full-wave simulation, and measurement.
