英文摘要：

VSWR is one of the important transmission characteristics of RF coaxial cable. The 3D finite element analysis models of RF coaxial cable are developed with field-road combined method. The affecting factors of VSWR of RF coaxial cable are theoretically investigated. The accuracy of the inner and outer diameter of the conductor, insulation quality, degree of eccentricity of the inner and outer conductors and conduetivity are studied further.
