Large-Scale Integrated MEMS-Based ESA for MMW Applications

The proposed project will directly and effectively enable practical near-term realization of highly efficient, reliable, and affordable Electronically Scanned Array (ESA) antennas at Millimeter-Wave (MMW) frequencies. Based on novel packaging and integration of proven innovations (from ThinKom and Memtronics) in the areas of MEMS phase-shifters, low-loss feed networks, and integrated high-efficiency CTS radiating aperture technologies, a highly modular scaleable high-gain antenna "building block," suitable for 1-D and 2-D scanning implementations, will be realized. Specific component and architecture flexibilities enable interchangeable realization of both planar and conformal (curved) antennas, thereby enabling the broadest possible range of low-profile, low-observable, low-drag configurations for a variety of terrestrial, ground-mobile, airborne, and space-based communication and sensor applications. Owing to specific innovations in the reduction of device, feed, interconnection, and radiator losses, MMW antenna efficiencies at or above 50% will be realized. In addition, a variety of cost innovations are expected to realistically support near-term cost targets at or below $10 per square wavelength. Phase I of this effort will study, trade, and design constituent components and integrated packaging of a planar (or conformal) high-gain (30 dB) 35 GHz ESA-based CTS antenna contemplated for fabrication, test, and evaluation in Phase II.
