Abstract
Methods of preparing composite dielectric materials used in lenses for communications antennas. The methods can include one or more of: using induction heating to expand expandable dielectric particles; combining expandable dielectric particles with pre-expanded dielectric material prior to expansion; and/or performing the expansion of the expandable dielectric particles within a lens or other container.
