1. A polymer structure having a spatially gradient dielectric constant, the polymer structure comprising:
a unified body of dielectric material comprising an open-lattice cell structure comprising a plurality of unit cells, wherein each unit cell is integrally connected with an adjacent one of the unit cells;
wherein an average dielectric constant of the unified body of dielectric material varies from a portion of the body to another portion of the body; and
wherein the spatially gradient dielectric constant of the polymer structure has endpoints in a range from 20 to greater than 1, measured at 10 GHz, 23° C., and 50% relative humidity.
