AbstractThinKom, with > 10 years experience developing and producing lightweight, low-cost and high-efficiency antennas using Continuous Transverse Stub (CTS) antenna technology (and a license to CTS from Raytheon), and two years of commercial antenna technologydevelopment, including innovative antenna technologies such as WAVETRAP (wideband, near-omni offering beam shaping and beam steering capabilities) and a dual band variant of VICTS (Variable Inclined CTS), will investigate and recommend a Wideband RadiatingAperture antenna technology and design addressing the K, Ka and Q operating bands. Recommended antenna (or antennas) will exhibit these features: 1) total radiation efficiency > 70% (< 0.5dB ohmic loss between amplifiers and free space), 2) offer low(approximately 10 ohms) match to amplifiers (e.g. HPA & LNA) to achieve high power added efficiency and low noise figure, 3) be physically low profile (< 2-3 inches thick), small (about 15-20 inches in diameter) and light weight (< 50 lb), 4) be of robustphysical construction to withstand both airborne and ground vehicle environments, and 5) use low cost commercial materials and processes to achieve affordability. An antenna exhibiting all the features described in the technical abstract, plus supportinga multiple broad operating bandwidth would also have many applications for mobile high data rate satellite communications, such as mobile (COTM) internet access from aircraft and ground vehicles. When the operating bandwidth spans from 17 to 21 GHz, 28 to31 GHz and 43-46 GHz (not needed for commercial, however, V-band may be needed in the future) as well as Ku-band frequencies, then the antenna can support the diversity of commercial satellite communication functions needed now and in the near or farfuture for mobile internet access and other business communications such as full motion video conferencing. In this case the military products being sought include coverage of the commercial K and Ka-band satellite communication bands, specifically sothat the military can make use of both commercial and military frequency allocations to maximize the likelihood of assured affordable communications. This of course means that these products can be directly translated into commercial products.Since these products make use of the CTS technology, for which ThinKom is the only commercial company, and the dual band VICTS technology, for which ThinKom is holder of IP rights, then this SBIR funded project will directly enable ThinKom products for thewell-established business jet market place (roughly a 5,000 to 15,000 addressable market), the growing (being developed by such companies as Connexion By Boeing) commercial (airliner) jet market place (about 5,000 near to mid term addressable market), andthe commercial (and maybe eventually consumer) ground vehicle market place (presently < 50,000 per year and potentially > 100,000 per year addressable market). For the business jet and commercial jet markets, our dual band VICTS architecture promises toallow ThinKom to drive the antenna
