Abstract

A split cylindrical resonant cavity comprises an upper cylindrical resonant cavity body and a lower cylindrical resonant cavity body which are separated from each other. The upper cylindrical resonant cavity body comprises an upper-portion cylindrical cavity body with one end closed and one end open, a pair of upper-portion strip-shaped conductor flanges, an upper-portion coupling ring and an upper-portion coaxial transmission line, the upper-portion strip-shaped conductor flanges are arranged on the open end of the upper-portion cylindrical cavity body, the upper-portion coupling ring is arranged inside the upper-portion cylindrical cavity body, the upper-portion coaxial transmission line is connected with the upper coupling ring and penetrates the top wall or the side wall of the upper-portion cylindrical cavity body to connect the upper-portion coupling ring to the outside; the lower cylindrical resonant cavity body comprises a lower-portion cylindrical cavity body with one end closed and one end open, a pair of lower-portion strip-shaped conductor flanges, a lower-portion coupling ring and a lower-portion coaxial transmission line, the lower-portion strip-shaped conductor flanges are arranged on the open end of the lower-portion cylindrical cavity body, the lower-portion coupling ring is arranged inside the lower-portion cylindrical cavity body, the lower-portion coaxial transmission line is connected with the lower coupling ring and penetrates the top wall or the side wall of the lower-portion cylindrical cavity body to connect the lower-portion coupling ring to the outside.

Description

technical field [0001] The invention relates to the field of testing the dielectric properties of high-frequency printed board substrates, more specifically, the invention relates to a split cylinder resonant cavity for measuring the dielectric properties of high-frequency printed substrates. Background technique [0002] Dielectric properties are one of the important performance parameters of high-frequency printed substrates. Accurately testing the dielectric properties of high-frequency printed substrates is crucial to high-frequency circuit design, production, finalization and debugging of high-frequency electronic products For some applications, the test accuracy of the dielectric constant of the printed board is required to be within 2%. [0003] The test accuracy of dielectric properties is related to factors such as frequency, uniformity, anisotropy, temperature, surface roughness, etc. For anisotropic materials, the direction of the test field is crucial. The high-...
