Notch Filter Using a Split Ring Resonator

Application ID: 18835

A split ring resonator (SRR) has a band-stop frequency response that rejects a certain range of frequency. This type of SRR structure is popularly used as a resonator itself and can be combined periodically to build artificial meta-materials.

In this model, a printed SRR on a dielectric substrate is coupled to a microstrip line. The entire circuit behaves as a notch (band-stop) filter, which can be used to block a specific signal frequency range.

The model instructions guide you in setting up an arbitrary shape as a port that supports (quasi-)TEM mode, by using a numeric port with the “Analyzed as a TEM field” option.

This model example illustrates applications of this type that would nominally be built using the following products:
