Abstract (en)
[origin: CA2875004A1] The invention relates to a bandpass filter for microwave-frequency wave which is frequency tunable, comprising at least one resonator (R), -each resonator comprising a cavity (30) having a conducting wall (50) substantially cylindrical in relation to an axis Z, and at least one dielectric element disposed inside the cavity, -the said resonator resonating on two perpendicular polarizations having respectively distributions of the electromagnetic field in the cavity that are deduced from one another by a rotation of 90° and according to one and the same frequency, -the wall of the cavity (50) comprising an insert section (20) facing the said element having a different shape from a section not situated facing the element, -the insert section (20) and the element being able to perform a rotation with respect to one another in relation to the axis Z so as to define at least a first (P1) and a second relative position differing by an angle substantially equal to 45° to within 20°.
