Abstract :
In this paper, tunable Alters based on the varactor-loaded spilt-ring resonant structure coupled to the micropstrip line have been fabricated and measured. Using a CRR structure where the splits of the SRR structures are removed, the band gaps in transmission coefficients which are due to magnetic resonance of SRRs were identified.
