Abstract :
In this paper, an effective numerical method to carry out a modal analysis in infinite-array approach is presented. Strong reactive fields, with a non-negligible vertical component, at the resonant frequency are evidenced. The same effects are observed for a finite array, in which evanescent waves are reflected by the edges, resulting in strong array truncation effects at the resonance. This work may lead to the establishment of new design criteria for artificial ground planes devoted to low-profile antennas
