Annex A. Science And Technology Objectives (STOs)
Army Science and Technology Master Plan (ASTMP 1997)

IV.G.07. Antennas for Communications Across the Spectrum. The objective of this STO is to develop, leverage, and apply emerging antenna technology to reduce the number of antennas, reduce the visual signature (conformal), reduce the cosite and control problems, and increase efficiencies and radiation patterns in the ranges of 2MHz to 2GHz. A second goal is to provide On-The-Move (OTM) SATCOM antenna capabilities in the Triband (C, X, Ku) and EHF bands. Five different technologies will be explored to address different applications. For SPEAKeasy applications, wideband technology will be exploited. For air and ground vehicles, Structurally Embedded Reconfigurable Antenna Technology (SERAT) and structure tuned antenna techniques will be used. SHF and EHF low profile, self steering, On-The-Move (OTM) antenna technology will be applied to the SATCOM applications. The initial thrust will be to address the broadband requirements for SPEAKeasy. Following this, the effort will be expanded to pursue the remaining efforts concurrently. By FY98, a wideband SPEAKeasy antenna will be demonstrated. A UHF Conformal antenna (SERAT) will also be demonstrated in FY98 on a Blackhawk, followed by a demonstration on a selected ground platform in FY99. A structured tuned VHF antenna will be fabricated and demonstrated in FY99 on a ground vehicle. A Triband (C, X, Ku) OTM self steering SATCOM antenna capability will be demonstrated in FY00. In FY01, an OTM self-steering EHF SATCOM antenna capability will be demonstrated.

Supports: SPEAKeasy, Future Digital Radio, Tactical Airborne and Ground Vehicles, Direct Broadcast Satellite, DSCS, and MILSTAR.
