Abstract
Ear-worn devices may include one or more structural elements formed of high-dielectric material. The position and shape of the structural element may be selected relative to an antenna of the ear-worn device to provide specific enhancements of the electric and/or magnetic field generated by the antenna. The structural elements may include a host resin material and a plurality of dielectric material elements. The structural elements may have an effective dielectric constant greater than 5. One or more loading strips may be used to tune a resonating structure formed by the antenna and the structural elements. The antenna may be an antenna array with structural elements disposed between elements of the array.
