摘要 | To meet the requirements of low profile and broadband frequency selective surface (FSS) structure with stable transmission characteristics, a novel broadband FSS based on composite coupling structure was proposed. Based on the phase-amplitude modulation between adjacent periodic sub-units, a novel broadband FSS model was established. Subsequently, its electromagnetic transmission characteristics and the influence of the scanning angle on its electromagnetic transmission characteristics were calculated using full-wave numerical simulations. Finally, an FSS prototype of 500 mm 500 mm was fabricated using the printed circuit board (PCB) technology and tested using the free space method. The experimental results show that the proposed FSS structure has stable broadband characteristics, and its bandwidth at -3 dB is 8.85 GHz. The top of the stopband is flat and its edge is steep. The FSS also shows good incident angle stability. Based on phase-amplitude modulation theory, a novel method to broaden the working bandwidth of FSS is proposed. The novel broadband FSS structure designed by this method has potential engineering significance. 2022, Science Press. All right reserved. |
