【摘要】 不同于传统的频率选择表面,小型化频率选择表面(Miniaturized-element Frequency Selective Surface,MEFSS)的工作频率取决于其基本结构单元中的金属结构的内禀电容和电感,而不是单元的结构共振频率。本文设计制备了工作在X波段和Ku波段的MEFSS样品,实验测试结果表明该结构在垂直入射时的-1dB高达64%,并且在不同极化方向以及大角度入射下(60°)依然有较好的传输性能。该宽频带的MEFSS结构特别适用于雷达罩和天线罩等应用场合。更多还原

【Abstract】 Different from the traditional frequency selective surface,the working frequency of the miniaturized-element frequency selective surface(MEFSS) is based on the intrinsic capacitance and inductance of its unit cell but not the structure resonance.We designed and fabricated a wideband MEFSS sample working at X and Ku band.The measurements demonstrated that the-1 dB bandwidth is over 64% at normal incidence and also have good transmission properties with different polarization and different incident angle.The applications of the wideband MEFSS are especially on the radomes.更多还原
