Abstract

This article presents an investigation of the effect of applying Penrose symmetry on microstrip antenas, evaluating the influence on the radiation parameters from changes in the dimensional values of this type of structure. This quasi-periodic model will be applied to the antena ground plane for an operating frequency of 2.45GHz. The variation of the radius of the quasi-periodic Penrose symmetry in the ground plane of the antena will be analyzed. The measured and simulated results validate the influence of this arrangement on the antena radiation parameters, increasing gain and bandwidth.
