T/CSTM 00750-2022 Active

Scope: This document specifies the measurement method for the real part of the relative permittivity and the tangent of the loss angle of inorganic materials, composite boards, engineering plastics, and other materials with a frequency range of 20GHz to 60GHz using the open hemisphere resonant cavity method. Among them, the measurement range of the real part of the relative permittivity is 2 to 30, and the measurement range of the tangent of the loss angle is 0.05 to 0.0001. This document is applicable to the measurement of the real part of the relative permittivity and the tangent of the loss angle of inorganic materials such as silicon oxide, aluminum oxide, aluminum nitride, zirconium oxide, and boron nitride; organic/inorganic composite boards such as polytetrafluoroethylene filled with titanium dioxide; and organic engineering plastics such as polyetheretherketone and polystyrene. It is also applicable to the measurement of the real part of the relative permittivity and the tangent of the loss angle of other similar solid dielectrics, composite boards, engineering plastics, and their films.
