Abstract: An energy supply arrangement for feeding microwave energy from a microwave source to the oven cavity of a microwave oven. The energy supply arrangement comprises a transmission line of the type having a conductor arranged at a small distance from a ground plane, a so-called micro-strip line. This micro-strip line is arranged within the oven cavity near the bottom wall and is, for example, in the shape of a spiral conductor disposed about a central energy feed point and dimensioned such that it radiates energy into the cavity at the same time that energy propagates along the line.
