a resonator body provided on the planar surface, the resonator body formed of a dielectric material, the resonator body having at least a first planar surface and a second planar surface opposed to the first planar surface;
a plurality of coupled metal inclusions provided within the resonator body, each of the metal inclusions extending substantially perpendicularly from the first planar surface and at least partially through the resonator body toward the second planar surface, each of the metal inclusions having a generally constant cross-section along its height; and
an excitation structure for exciting the resonator body, the excitation structure disposed on the substrate.

Abstract
Antennas suitable for use in compact radio frequency (RF) applications and devices, and methods of fabrication thereof. Described are resonator antennas, for example dielectric resonator antennas fabricated using polymer-based materials, such as those commonly used in lithographic fabrication of integrated circuits and microsystems. Accordingly, lithographic fabrication techniques can be employed in fabrication. The antennas have metal inclusions embedded in the resonator body which can be configured to control electromagnetic field patterns, which serves to enhance the effective permittivity of the resonator body, while creating an anisotropic material with different effective permittivity and polarizations in different orientations.
