Abstract: This paper deals with single layer Frequency selective surface (FSS) which acts as a double band reject filter. The two stop bands are really broad with percentage bandwidth of 26.67% and 14.53%. The maximum and minimum band separation for this proposed design is around 45 dB and frequency ratio is more than 1.9.This results are almost same for different incident angles.. This design is investigated theoretically by ANSOFT® Designer software and practically by standard microwave test bench and the both results show a good agreement.
Keywords: Frequency Selective Surface; Band reject filter, Band separation, Frequency ratio.
