Abstract
Abstract Means for coupling a cavity resonator to a conductor circuit and/or a further cavity resonator wherein a coupling window or opening is present at the wall between the cavity resonator and the conductor circuit and/or the further cavity resonator. According to the invention the coupling window or opening possesses a cross-section which at least approaches a U- or Vshape having a tongue, the axis of symmetry of which is at least approximately parallel to the vector of the electrical field of the resonator at the region of the coupling window or opening. The length of the tongue is chosen such that the tongue together with the coupling window forms a lambda /4 resonant circuit working with the TEM-mode. The method of tuning the coupling according to the invention contemplates bending or rotating the tongue so as to change the coupling factor.
