Patent abstract
A BAW resonator includes a resonator region having a piezo-electric layer between two excitation electrodes, wherein an acoustic standing wave forms when operating the BAW resonator at a resonant frequency. Furthermore, the BAW resonator includes a leaky wave reflection structure formed to reflect leaky waves generated when operating the BAW resonator, wherein the leaky waves propagate in a direction differing from a propagation direction of the acoustic standing wave.
