Electronic component supporting mediums includes dielectric support material having voids adapted to include the use of air as a dielectric, which is commonly used in printed circuit boards and electrical connectors. The support medium provides physical support to conductive connections and a mechanical structure to enable electrical connections between electronic components. Support structures including air as a dielectric can be provided in the form of printed circuit boards and electrical connectors. A printed circuit board wherein said dielectric material comprises a low loss material. The support medium can comprise a low loss material such as air, FR-4, Teflon material, and plastic.
