Abstract
The present invention relates to a tunable resonating arrangement comprising a resonator apparatus (), input/output coupling () means for coupling electromagnetic energy into/out of the resonator apparatus, and a tuning device () for application of a biasing voltage/electric field to the resonator apparatus. The resonator apparatus comprises a first resonator () and a second resonator (). Said first resonator is non-tunable and said second resonator is tunable and comprises a ferroelectric substrate (). Said first and second resonators are separated by a ground plane () which is common for said first and second resonators, and coupling means () are provided for providing coupling between said first and second resonators. For tuning of the resonator apparatus, the biasing voltage/electric field is applied to the second resonator ().
