摘要
Abstract
To solve the breakage failure of antenna caused by excessive heat loss of dielectric loss at the opening of the end of the high-power communication antenna,a theory analysis about the heat generation mechanism of dielectric loss is carried out and a 3D quasi-static electrical field is established to study the decreasing method of heat generation caused by dielectric loss and the electric field homogenization at the terminal opening of high power communication antenna.The research results show that:the power of dielectric heat loss has the quasi square relationship with the electric filed strength;using semi-conductive as the outer sheath material and increasing the radius of curvature of the load-bearing fittings are the effective methods to ameliorate the electric field distortion;installing the grading fittings at the end of the antenna is regard as the most promising and effective method to solve the electric field distortion problem fundamentally.关键词
