The structure, performance and application prospects of the prepared ceramics.

Caption

Sc3+ suppresses oxygen vacancy formation and regulates the valence ratio of Mn/Fe, achieving highly linear thermistor characteristics within an ultra-wide temperature range; meanwhile, the synergistic effect of the lattice stabilization effect induced by Sc3+ and the octahedral site bond valence strengthening mechanism endows the material with excellent microwave dielectric properties. Based on the prepared ceramic, the cylindrical dielectric resonator antenna exhibits high radiation efficiency and gain at the 12 GHz frequency band, verifying its engineering application potential in satellite communication front-end modules.
