基于表面处理的抗充放电微波能量发射微带天线
Charge-discharge resistant microstrip antennas based on surface treatment
摘要
Abstract
With the application of microstrip phased array antennas in aerospace,the charging and discharging problems of antennas caused by the space environment warrant significant attention.This paper carries out research on the regulation of Secondary Electron Emission(SEE)from dielectric surfaces by surface coating and surface configuration.Experimental studies have shown that magnetron sputtering of ceramic thin films on the surface of microstrip antennas can effectively increase the Secondary Electron Emission coefficient(SEE coefficient)at the E2 point and the SEE coefficient in the high-energy range of the material,demonstrating that surface coating methods possess electron beam irradiation resistance capabilities.On this basis,taking an X-band microstrip antenna as an example,the influence of surface treatment hardening methods on antenna charging and discharging effects is experimentally analyzed.The results show that under surface charging conditions with electron energies of 1～20 keV and beam current densities of 1～100 nA/cm2,the irradiated dielectric material of the hardened microstrip antenna exhibits a 72%reduction in dielectric constant variation range,a 40%increase in the threshold for charging and discharging effects,and under high-power operating conditions(peak power of 50 W),the antenna element demonstrates a frequency shift of 0.19%and a radiation efficiency ratio of 62.63%.关键词
