  • Patent number: 6522304
    Abstract: An integrated horn antenna device with an integrated circuit (IC) chip including a metallic horn structure having a wide aperture, a horizontal waveguide with a tapered via that electromagnetically communicates with a vertical waveguide structure to transmit energy to and from an electronic sub-component transceiver device forming part of the IC chip. Another embodiment of the invention comprises a plurality of multiple discrete IC chips having the integrated horn antenna devices incorporated therewith forming a module for data transmissions between these IC chips. Another embodiment of the invention includes additional external waveguide structures such as optical fibers external to the chips, where radiation is aligned between the horn structures and these waveguides. Dual damascene processing is used to fabricate the horn antenna device within the IC chip.
