Broadband Equivalent Circuit Model for a Coplanar Waveguide Line Loaded with Split Ring Resonators

Abstract EN

A new equivalent circuit for a coplanar waveguide loaded with split ring resonators is presented.

The traditional circuits that model these devices are only able to characterize the left-handed propagation band, and their response is very similar to the real one within a very limited bandwidth.

In contrast, this proposed broadband equivalent circuit is able to portray not only the left-handed propagation band, but also the right-handed one that occurs at higher frequencies.

Besides, the response of this kind of basic cells can be adjusted with the proposed circuit model in a bandwidth close to a decade.
