Design of Bandpass Filters Based on Metamaterials

Abstract

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 $\varepsilon \mathbf {r} =2.2$, tangential losses tan ($\delta $) $=0.0009$ and a thickness of h $=0.508$ mm.
