Abstract
A microwave heating apparatus includes a solid state microwave energy source, a first dielectric resonator antenna that includes a first exciter dielectric resonator and a first feed structure in proximity to the first exciter dielectric resonator, one or more additional dielectric resonators stacked above the top surface of the first exciter dielectric resonator to form a vertically-stacked dielectric resonator antenna array. The first feed structure is electrically coupled to the microwave energy source to receive a first excitation signal, and the first exciter dielectric resonator is configured to produce a first electric field in response to the excitation signal provided to the first feed structure.
