Abstract: A system is provided for three dimensional coaxial transmission of signals in a micro-machined component, the system having, a micro-machined component matrix with a first metallic sheet having a plurality of first access holes disposed therein; a second metallic sheet having a plurality of second access holes disposed therein; a plurality of metal posts disposed between the first and second metallic sheets such that the metallic sheets are maintained at a desired distance; walls defining a coaxial transmission channel; and a coaxial transmission core disposed within the channel.

Abstract: An antenna having: a beam forming network; an array of antenna elements; and a parallel plate region coupling the array of antenna elements and the beam forming network formed on a common, folded dielectric substrate. The beam forming network includes strip conductor circuitry separated from a ground plane conductor by a portion of the substrate. The array of antenna elements comprising strip conductor circuitry separate from a ground plane conductor by a second portion of the substrate. The parallel plate region is disposed about a folded region of the substrate and includes a pair of conductive plates separated by the folded region of the substrate. With such arrangement, a compact antenna is provided using the folded substrate. Also, spurious radiation (which has been found to radiate when strip conductor circuitry is disposed about the folded region to couple the array of antenna elements and the beam forming network) is confined by the parallel plate region.
