Abstract
A filter includes a waveguide with at least one impedance structure with a resonant frequency. The impedance structure is positioned in the waveguide to reflect signals at the resonant frequency. The filter can be tunable by including variable capacitance devices in the impedance structure(s) so that the resonant frequency can be adjusted.
