Abstract
An ignition unit producing an ignition in a combustion chamber includes an electrode that has a tip section that is exposed to the combustion chamber when the ignition unit is fitted on a combustion engine. The electrode forms part of a microwave resonating structure that radiates a microwave field into the combustion chamber when a microwave excitation signal is applied to the electrode. A winding is electrically coupled to the electrode. The winding and the electrode form part of a radiofrequency resonator that radiates a radiofrequency field into the combustion chamber when a radiofrequency excitation signal is applied to the winding. A microwave signal path transfers the microwave excitation signal from a signal input connector on the ignition unit to the electrode. The microwave signal path includes an inductive portion and a capacitive coupling structure adapted to provide a capacitive coupling from the inductive portion to the electrode.
