Abstract (en)
[origin: EP2690703A1] The filter (100) has an output dielectric element (E1) for carrying out a rotation about an output rotation axis (X1), where a recess (42) allows the rotation of another dielectric element while keeping an output excitation element (SN) inside the recess. The dielectric elements are formed in flat shape with height, which is less by a factor of 3 than the smallest external dimension in a plane perpendicular to a direction supporting the height. The rotations of the dielectric elements allow the modification of the central frequency of the filter.
