Processing, Packaging, and Characterization of Electroceramic Materials for Phased Array Antennas
Abstract
As a part of an effort to optimize the electronic device performance in the ceramic phase shifter, various composites of BSTO combined with other nonelectrically active oxide ceramics have been formulated. In general, the composites have reduced dielectric constants and loss tangents and have high tunabilities, which reduce the overall impedance mismatch and the insertion loss of the device. The combination of electronic properties of these materials offer substantially higher operating frequencies, 10 GHz and above. Grain size and phase analysis have examined use SEM and X-ray diffraction. The packaging of the phase shifter materials electroding materials, electrode shapes, and encapsulation materials will be discussed. Barium strontium titanate.
