The introduction of fractal perturbations on the geometry of a square patch antenna lead to multiple frequency resonance. These perturbations may be added or subtracted to the antenna geometry, possibly leading to different results. The aim of this project is to study the radiating behavior of the modeled antenna in both of the above conditions, exploiting as successive step an optimization tool in order to define an optimal antenna geometry which comply with a given set of frequency bands. date: 2013 date_type: published institution: University of Trento department: ELEDIA Research Center@DISI thesis_type: masters referencetext: [1] F.
