<p>The invention relates to serial microwave feeding to a cavity of a microwave oven in order to provide heating of a load that is placed in the cavity. Any microwave radiation that is reflected from a first feeding port is directed, preferably via a microwave circulator, to a second feeding port. The radiation that is reflected from the first feeding port is thus fed to the cavity via the second feeding port.</p> |
