Abstract

Abstract: For Studying higy-property phase shifter materials in a phase array antenna of autotrack synchronous communication
satellites, lithium ferrite Li_0.625Zn_0.1Ti_0.25Sn_0.1Fe_1.925O₄ was prepared by using a standard ceramic flowing oxygen sintering technique
and adding some benificial materials such as MnCO₃, Bi₂O₃ etc. The microwave properties of ferrite phase shifter materials Li_0.5(1-y)Zn_yFe_2.5(1-0.2y)O₄
were discussed. The measured results show that lithium ferrite Li_0.625Zn_0.1Ti_0.25Sn_0.1Fe_1.925O₄ possesses high Curie temperature and low dielectric loss.

Key words: ferrite phase shifter materials, saturation magnetization, Curie temperature
