Ceramic Ferroelectric Material
US Patent:
5312790, May 17, 1994
Filed:
Jun 9, 1993
Appl. No.:
8/076291
Inventors:
Louise C. Sengupta - Woburn MA
Eric Ngo - Brighton MA
Steven Stowell - Jamaica Plain MA
Gary Gilde - Brighton MA

Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
C04B 3546
US Classification:
501137
Abstract:
A novel ceramic ferroelectric material having a low dielectric constant, loss and high tunability. The material is a composite comprising Barium Strontium Titanate (BSTO) and a ceramic material having a low dielectric constant. The preferred composite is represented by Ba. sub. 1-x Sr. sub. x TiO. sub. 3 -Al. sub. 2 O. sub. 3, wherein x is greater than 0. 00, but less than or equal to 0. 70, and wherein the percent weight ratio between Ba. sub. 1-x Sr. sub. x TiO. sub. 3 and Al. sub. 2 O. sub. 3 ranges from approximately 99%-40% and 1%-60%, respectively. The novel materials possess superior electronic properties; and they may be employed in various antenna systems.
Electronically Graded Multilayer Ferroelectric Composites
US Patent:

Assignee:
The United States of America as represented by the Secretary of the Army - Washington DC
International Classification:
B32B 1700
US Classification:
428699
Abstract:
A laminated ceramic ferroelectric material has adjacent layers of Barium ontium Titanate (BSTO)--oxide composite stacked in order of descending oxide content and sized in thickness to produce a generally equal capacitance across each layer, resulting in a material having a graded dielectric constant for use in phased array antenna, for example. The oxides are from the metallic oxide group consisting of alumina, zirconia and magnesia and the layers are produced by tape casting.

International Classification:
C04B 3546
US Classification:
501137
Abstract:
A novel ceramic ferroelectric material having a low dielectric constant, extremely low loss and high tunability. The material is a composite comprising Barium Strontium Titanate (BSTO) and a ceramic material having a low dielectric constant. The preferred composite is represented by Ba. sub. 1-x Sr. sub. x TiO. sub. 3 --MgO, wherein x is greater than 0. 00, but less than or equal to 0. 75, and wherein the percent weight ratio between Ba. sub. 1-x Sr. sub. x TiO. sub. 3 and MgO ranges from approximately 99%-40% and 1%-60%, respectively. The novel materials possess superior electronic properties; and they may be employed in various antenna systems at both microwave and millimeter wave range frequencies.
