Army Science and Technology Master Plan (ASTMP 1997)

IV.J.06. Ferroelectric Phase Shifter Materials. The cost of phase array antenna is predominantly dependent on the cost of its microwave phase shifter. This STO will develop the processing methodology to produce a microwave phase shifter from a low cost, low power dissipation, voltage driven ferroelectric composite ceramic and thereby reduce the cost of a phase shifter element from $5000 to $200. By FY96, demonstrate thick film low-low phase shifter material for use at 15GHz. By FY97, demonstrate a thick film phase shifter material for use at 25GHz. By FY98, demonstrate a thick film, low cost phase shifter material in phased array antenna operating at 35GHz. The product of this STO will be a prototype replacement for the "ferrite phase shifter element" designed in mid-higher communication frequency for the "geodesic cone antenna component" in the following systems: Ground-Based Common Sensor; Air Reconnaissance Low; Aerial Common Sensor; Advanced Quickfix; Guardrail.
