Arrangement and method relating to coupling of signals to/from microwave devices
Patent, 2001

An arrangement for coupling electro magnetic waves, particularly microwaves, into and/or out of a device which includes a dielectric resonator having a non-linear dielectric substrate with a high dielectric constant and a coupling loop. The dimensions of the resonator and the coupling loop are related to the resonant frequency of the resonator. The coupling loop is so arranged in relation to the resonator that the magnetic field lines around the coupling loop match the internal film distribution of at least one mode, which has been selected to be excited, so that only that mode is excited. Coupling is provided only for this mode. The length of the coupling loop is comparable to or larger that the dimensions of the resonator.
