Nanocomposites for antenna-feeder systems

The paper presents results of study of frequency dependence of permittivity and permeability of composite materials based on various polymer matrices and fillers in the form of nanoscale powders - nanoparticles of Si, carbon nanotubes, and magnetite nanoparticles. It is shown that, using the nanodisperse electrically conducting fillers, it is possible to obtain materials with the required dielectric permittivity, and in the case of magnetic nanoparticles to obtain materials with the appropriate magnetic properties. The results may be useful in the development of antenna-feeder systems that include elements that focus or absorb microwave radiation.
