Résumé :

The aim of this work consists of a design and a numerical study of a reconfigurable patch antenna by integrating a thin film of ferrite with a thickness of 50 μm. This antenna is printed on a magneto-dielectric composite substrate. The application of a static magnetic field, that strongly influences the permeability of the ferrite, allows the agility control of the resonant frequency. For this purpose, a patch antenna is studied and designed to operate at 2.45 GHz (suitable for Wi-Fi applications). The obtained results show that the proposed antenna can achieve a tuning in resonant frequency range of 5-87 MHz.
