Coupling capacitance dielectric board for coaxial resonators

摘要

A dielectric resonator apparatus has a main resonator part containing a plurality of resonance circuits, a coupling board with electrodes thereon individually connected to the resonance circuits for capacitively coupling them, and a dielectric board superposed on the coupling board for increasing the capacitive coupling of the resonance circuits by providing floating capacitance therethrough which are connected in parallel to the capacitance between the resonance circuits through the coupling board.
