ÉTUDE DES STRUCTURES PÉRIODIQUES PLANAIRES ET CONFORMES ASSOCIÉES AUX ANTENNES. APPLICATION AUX COMMUNICATIONS MOBILES

Abstract : This thesis can be divided into two distinct parts : the first part deals with periodic planar structures associated with antennas while in the second part, conformal periodic structures are studied. Though the first part has already been studied before (in the last few years), the contribution of the thesis are a new analysis (source inside structure, array theory based analytical method...) and new results (frequency resonance and extrema, structures having dual allowed and propagated frequency bands, matching of an antenna in a planar periodic structures, angular aperture in function of frequency...). Conformal periodic structures are however new. We do a systematic study of these structures. The main application of this work is a RNRT project whose aim is the realization of GSM-UMTS base station antennas. An antenna based on a conformal periodic structure has been designed corresponding to the required specifications.
