Polarization stable ultra-wide-band Frequency Selective Surface for Ku- and K- band applications

This paper presents the design of an ultra-wide passband Frequency Selective Surface for Ku- and K- band applications. The proposed FSS exhibits an extremely large passband of 24.4 GHz in the 5.8-30.2 GHz range with an exceptional 135% fractional bandwidth. Moreover, it shows a stable transmission response for both TE and TM polarizations up to 45° of the incident angles.
