Design of Bandpass Filters Based on Metamaterials

We will focus on the design of a bandpass filter based on complementary ring-shaped resonators. This structure is intended to operate in the band [0.5-3] GHz. The substrate used at a relative dielectric constant of ε
_r
= 2.2, tangential losses tan (δ) =0.0009 and a thickness of h = 0.508 mm.
