AbstractThis SBIR Phase I program will address the fabrication and testing of voltage variable dielectrics (VVD) in which the refractive index (n) can be E-field tuned providing electronic scanning in the microwave regions. In collaboration with Hughes' Radar Division, the manufacturing of large area composites based on the perovskite Barium Strontium Titanate (BST) will be integrated into a continuous transverse antenna architecture for phased array radar concurrent to this effort will be investigation of thick film BST or cofired / tape-cast BST for fabrication of voltage tunable microwave frequency capacitors. The Phase I research will provide a basis for the manufacturing of BST composites with further optimization in Phase II, including device specific applications such as automotive collision warning devices, airport encursion, sensors, etc.
