Abstract: An electromagnetic device includes at least one dielectric resonator antenna, DRA, and at least one dielectric waveguide, DWG, configured so that during operation of the electromagnetic device, the at least one DRA provides an electromagnetic signal to the at least one DWG, or the at least one DWG provides an electromagnetic signal to the at least one DRA. The at least one DWG has a three-dimensional, 3D, shape that is different from a 3D shape of the at least one DRA.

Abstract: The primary and/or secondary coils of a relatively high power planar transformer are integrated together with a laminated busbar, thereby incorporating together the planar transformer and the busbar as a single component. A coil is cut out or otherwise formed in at least one busbar conductor, and when electrically connected, the busbar coils act as part of the primary and/or secondary circuit of the transformer. One or more coil lead frames are embedded in the laminated stack, and when electrically connected, form the primary and/or secondary circuit, respectively, of the transformer. Insulating material coils are also embedded within the laminated stack. The center leg of an E-shaped ferrite core passes through the center opening of each of the busbar coils, the coil lead frames, and the insulating material coils. The E-shaped core is located next to (i.e., with an opening) or closed with, an I-shaped or E-shaped core.
