Abstract

This work proposes the use of split ring resonators (SRRs) as basic blocks for planar filters with dual-band band-pass frequency response. This application requires some geometrical modifications on the original SRRs used for metamaterial synthesis. The resonance frequencies and their dependence on the dimensions are analytically derived, and the field distribution on each SRR is studied in order to design the coupling and tuning mechanisms. The measurements of a manufactured prototype show the validity and potential of the proposed elements
