摘　　要：本文提出了1种单层孔径型的小型化频率选择表面。通过设计曲折型单元结构,增加谐振结构长度,从而使得该频率选择表面的单元尺寸大大缩减。基于曲折型设计的频率选择表面谐振频率为4.875 GHz,表现出带阻的特性,单元周期为谐振波长的0.06倍,-3 dB相对带宽为-17.9%,具有双极化工作能力,并且具有良好的入射角度和极化稳定性。This paper proposes a miniaturized frequency selective surface with a single layer aperture type.By designing the meandering unit structure,the length of the resonant structure is increased,so that the cell size of the frequency selective surface is greatly reduced.The frequency selective surface resonant frequency is 4.875 GHz,exhibiting band-stop characteristics,The cell period is 0.06 times the resonant wavelength,the-3dB relative bandwidth is-17.9%,has dual polarization working ability,and has good incident angle and polarization stability.
