Metamaterial Based FSS for Wireless Applications with a Compact Size

In this work, a rectangular SRR-based unit cell is proposed for 5.2GHz wireless applications. The proposed structure exhibits double negative metamaterial properties. A polymide dielectric substrate material with a dielectric constant of 3.5 and a thickness of 0.1 mm was utilized to construct and validate the proposed structure.A numerical simulation tool, CSTMW studio, which works on the FDTD method is used to simulate the structure. The unit cell works between 4.90 GHz and 5.94 GHz, yielding an overall bandwidth of 1.04 GHz with 11 of -46.32 dB and the unit cell is validated with ADS tool with equivalent circuit diagram.
