一种宽带吸波的隐身天线罩设计
Design of a Metamaterial Stealth Radome with Broadband Absorption
摘要
Abstract
Traditional absorption materials can't ensure the electromagnetic wave transmission in the working band and absorption outside the band simultaneously.A metamaterial stealth radome with the ability of broadband absorbtion is presented in this paper,which combines the absorption properties of the traditional absorbtion materials and the filtering properties of the frequency selective surface.Using the resonant properties of the metamaterials,artificial structures with broadband absorption are obtained.The impedance matching technology is further applied to improve the transmission in the antenna operating band and the absorption beyond the band.The metamaterial stealth radome with transmission band in Ku band and absorption band in higher frequency band is constructed by adjusting the size of the artificial structure.This radome can be used to reduce the radar cross section of an airborne antenna while the communicating function of the antenna is maintained.关键词
