Contribution à l'étude d'antennes miniatures reconfigurables en fréquence par association d'éléments actifs

Abstract : Current telecommunication systems and especially mobile terminals require compact antennas with significant bandwidth. But one of the well-known drawbacks of electrically small antennas is their very narrow frequency bandwidth. The aim of this study is to develop a miniature antenna with good performances. A compact omnidirectional antenna corresponding to the need of telecommunication systems is first studied. The antenna is miniaturised by two different techniques and developped. Due to this miniaturization, a weak bandwidth is obtained. Several solutions using frequency agility are subsequently studied. Modelization, simulation and experiments are presented in the thesis to validate the whole study. A BAN (Body Area Network) application of the antenna is finally given.
