Claim:
1. An assembly for confining electromagnetic radiation in a waveguide, comprising: an electromagnetic waveguide (EW) comprising walls that surround a cavity, wherein said walls have an aperture that opens to said cavity; and a substrate assembly disposed in said aperture and comprising: (a) a substrate comprising an antenna, wherein said antenna is located within said cavity and configured for transmission of electromagnetic radiation within said cavity, and (b) an integrated circuit (IC) electrically connected to said substrate, wherein said IC comprises a plurality of electronic components and a ground plane on one side of said IC, wherein said ground plane is located (i) between said plurality of electronic components and said antenna, (ii) across said aperture to reduce the area of said aperture and to reflect some of said electromagnetic radiation transmitted from said antenna directed to said aperture back into said cavity.
