Abstract

The invention discloses a terahertz waveband medium material, a preparation method and a method of preparing a dielectric medium therefrom. The chemical formula of the medium material is [(Mg<1 x>Al<2/3x>)<1/3>Nb<2/3>]O<2> + y wt% ABSMV, 0<=x<=0.3, and y=1 or 2. The medium material has the advantages of low sintering temperature, low dielectric loss, and moderate dielectric constant.

Description

technical field [0001] The invention relates to a material and a preparation method used in the communication field, in particular to a terahertz band dielectric material, a preparation method and a method for making a dielectric. Background technique [0002] With the rapid development of wireless communication in the era of big data, it is technically required that wireless communication devices have the characteristics of continuous development in the direction of high frequency (microwave, terahertz wave) and high gain (or low insertion loss). Based on this, communication devices such as dielectric antennas and filters require that the dielectric loss of the dielectric in the microwave or terahertz band should be low, and its dielectric constant should be moderate to meet the above requirements. However, the dielectric materials that can be used in the terahertz band still have the disadvantages of high dielectric loss and high sintering temperature. Contents of the in...
