A miniaturized and flexible frequency-selective surface (FSS) has been presented in this article with a unit cell size of 0.049 × 0.049 where is the free space wavelength at the lower cut-off frequency. In order to achieve an ultra-wide (?3 dB) second order pass band of 151.3% with enhanced selectivity factor of 0.887, a cascaded triple layered hybrid resonating structure has been proposed with
