Abstract:
A dielectric resonator comprising:a pair of upper and lower opposing conductive plates;a dielectric substrate disposed between said conductive plates;a first electrode disposed on one surface of said dielectric substrate, said first electrode having a first opening;a second electrode disposed on another surface of said dielectric substrate, said second electrode having a second opening opposing said first opening whereby said dielectric substrate between said first and second openings defines a resonator;a slit formed in said first electrode, said slit having opposing walls, said slit being connected to said resonator;a third electrode being separated from said first electrode;an insulating flexible substrate disposed above the third electrode and the slit;a fourth electrode being disposed on the lower surface of the insulating flexible substrate so that the fourth electrode opposes said third electrode and so that said third and fourth electrodes are attracted to each other in response to a voltage applied across said third and fourth electrodes;a fifth electrode being disposed on the lower surface of the insulating flexible substrate so that the fifth electrode opposes said slit.
