Moore Curve Fractal-Shaped Frequency Selective Surface for Multiband Applications

In this work Fractal based Frequency Selective Surface (FSS) is presented. Fractals are self-repetitive geometries that can provide a multiband operation. FSS unit cell designed using Moore curve fractals up to the third iteration and analyzed in terms of return loss and transmission coefficient. The FSS is designed over a Fr-4 substrate with a thickness of 1.6 mm. The Moore Curve shaped frequency Selective Surface (MCFSS) iteration 1 has a single-band operation at 8.56 GHz while MCFSS iteration 2 has dual-band operation at 4.3GHz and 8.59 GHz, and MCFSS iteration three has dual-band response at 2.36 GHz and 4.89 GHz.
