Abstract (en)
[origin: EP0973227A2] The dual mode ring resonator used in microwave applications has a conductor ring in the form of a closed ring (1) of rectangular shape with rounded corners (2-5). This in located between an input (8) and an output (9) line. The length of the ring is such that the resonator operates with odd harmonics.
