Dual mode ring resonator filter with a dual mode generating line disposed inside the ring resonator

Image Number 16 for United States Patent #7902945.

A dual-mode filter capable of providing a high degree of design freedom and/or tunability is disclosed. The dual-mode filter includes a ring resonator; an input feeder and an output feeder disposed substantially orthogonal with respect to each other and with respect to the ring resonator so as to be electromagnetically coupled to the ring resonator; and a dual-mode generating line disposed inside the ring resonator in a manner so that the dual-mode generating line does not overlap with a line extending from the input feeder or a line extending from the output feeder.
