NOVEL CERAMIC FERROELECTRIC MATERIAL |
摘要 |
A novel ceramic ferroelectric material having a low dielectric constant, 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 Ba1-xSrxTiO3-Al2O3, wherein x is greater than 0.00, but less than or equal to 0.70, and wherein the percent weight ratio between Ba1-xSrxTiO3 and Al2O3 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.
