Phase shifter materials with ZnTiSn-subtituted lithium ferrites

For Studying higy-property phase shifter materials in a phase array antenna of autotrack synchronous communication satellites, lithium ferrite Li0.625Zn0.1Ti0.25Sn0.1Fe1.925O4 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 Li0.5(1-y) ZnyFe2.5(1-0.2y)O4 were discussed. The measured results show that lithium ferrite Li0.625Zn0.1Ti0.25Sn0.1Fe1.925O4 possesses high Curie temperature and low dielectric loss.
