Tunable split ring resonators ( SRR ) filter based on barium-strontium-titanate thick film

Abstract

This paper presents a bandpass filter based on split ring resonators (SRR) with a frequency tunable passband. It consists of two SRRs, which are tuned by the embedded varactors built on Barium-Strontium-Titanate (BST) thick film ceramic. Each SRR embodies a transmission pole and a zero. The resonant frequency of the poles can be shifted by tuning the… (More)
