1. An electromagnetic device, comprising:
an electromagnetically reflective structure comprising an electrically conductive structure and a plurality of electrically conductive electromagnetic reflectors that are integrally formed with or are in electrical communication with the electrically conductive structure;
wherein the plurality of electrically conductive electromagnetic reflectors are disposed relative to each other in an ordered arrangement;
wherein each reflector of the plurality of electrically conductive electromagnetic reflectors forms an electrically conductive wall that defines and at least partially circumscribes a recess having an electrically conductive base that forms part of or is in electrical communication with the electrically conductive structure;
wherein the electrically conductive structure is configured to provide an electrical ground reference voltage of the electromagnetic device;
wherein each electrically conductive base of the plurality of reflectors and each electrically conductive wall of the plurality of reflectors are in direct electrical connection with the electrical ground reference voltage; and
further comprising a dielectric resonator antenna (DRA) disposed at least partially within a respective recess of an associated reflector of the plurality of electrically conductive electromagnetic reflectors, each respective DRA being disposed on an associated electrically conductive base;
wherein each respective DRA is any one of; a one-piece solid DRA, a hollow air core DRA, or a multi-layered DRA having dielectric layers with different dielectric constants.
