【摘要】 本文基于高阶LC滤波器原理提出了一种宽带圆极化频率选择表面,通过贴片和栅格交错排列,实现了宽带频率选择表面的设计,基于此设计的频率选择表面的3 dB带宽为1.14 GHz～3.17 GHz,相对带宽为94.6%,角度稳定性可以到30°,除了少数频点外,圆极化波入射后轴比变化小于3 dB。更多还原

【Abstract】 Based on the principle of high-order LC filter,a wideband circularly polarized frequency selection surface is proposed,and the design of wideband frequency selection surface is realized by staggering arrangement of patch and grid,and the 3 dB bandwidth of the frequency selection surface based on this design is 1.14 GHz-3.17 GHz,the relative bandwidth is 94.6%,the angular stability can be up to 30°,except for a few frequency points,the axis ratio changes after the incident of circularly polarized waves are less than 3 dB.更多还原
