Magneto-Dielectric Properties of Fe₃O₄/TiO₂/PTFE Composites and Antenna Simulation

Abstract:

In this paper, a novel composite of magneto-dielectric mixture Fe₃O₄/TiO₂ filled polymer PTFE was synthesized for a compact antenna application. Magnetic permeability, dielectric permittivity and related loss were measured and optimized. A planar patch antenna performance based on these composites with a center frequency at 1 GHz was simulated. The simulated antenna performances such as impedance bandwidth and radiation efficiency indicated that the antenna fabricated by this proposed composite could exhibit a better electrical property than that of conventional antenna printed on dielectric material.
