EN 171000:2001- 6 -1.3.6coupling factor kcoupling factor of a band-pass filter is the degree of coupling between two resonators. The coupling between dielectric resonators is mainly done either magnetically or electrically. Accordingto each case, the equivalent circuit of coupling is expressed by inductive or capactive coupling,respectively
Inductive coupling
Capacitive couplingThe coupling factor by inductive or capactive coupling is defined by the following equation,respectively:
M

C1 . C2WhereL1, C1 and L2 C2 are the resonance circuit elementsM is the mutual inductanceCmis the coupling capacitancek
is the coupling factor.In the case of a symmetrical circuit of coupling, the coupling factor can be obtained from tworesonance frequencies calculated or measured for the coupled resonators: fo2 – fe2
k = fo2 + fe2 Wherefe is the resonance frequency in the case of even mode excitation (open-circuitedsymmetric plane).fo is the resonance frequency in the case of odd mode excitation (short-circuitedsymmetric plane).The coupling factor of a band-stop filter is the degree of coupling between the resonator and thetransmission line.
The coupling factor k is defined as the ratio of the external power loss (Pe) of theresonator system to the internal power loss (Pu) of the resonator and can be expressed by afunction of quality factor as follows:
Pe
