| Abstract: | The effects of additives such as Bi2O3, MnCO3, SnO2 on the properties of barium strontium titanate/magnesium titanate (BST/MTO) compound ferroelectric material of phase shifters, including permittivity, loss tangent and tunability, are studied by orthogonal design. The mechanism is also presented and discussed. The results show that the material properties can be dramatically improved by properly controlling the additives. Of the obtained material, r is315,tgd 0.0028 and T 14.27%. |
