A Novel Wideband Wide-angle Frequency Selective Surface Composite Structure
A novel wideband FSS composite structure is proposed, Which use modified C-type sandwich cascaded structure and Hexagonal loop element with the characteristics of center symmetry in FSS design resulting in good electrical performance such as high transmission efficiency and stable working frequency band at a wide range of incident angle. The FSS sample is fabricated using low temperature pressing processes and then measured in anechoic chamber, The measured results show relative bandwidth of the FSS composite structure reaches to 45% (Transmission efficiency > 85%) for arbitrary incident angle from 0° 60° and both polarization. With the increase of the incident angle, the center resonant frequency tends to shift to higher frequency, the maximum offset of which is below 0.5 GHz. Inner envelope relative bandwidth is close to 41% (transmission efficiency > 85%) at a range of 0°~68° incident angle of vertical polarization wave and 0°~60° incident angle of horizontal polarization wave.
