ABSTRACT:
A microwave oven has an oven cavity in which a launch site for delivering microwave energy into the oven cavity is provided by a hole (6) in a wall (2) of the cavity and a match plate (10). In order to improve the distribution of microwave energy in the cavity, the oven also has a second wall (4) partially covered on its internal side by a second match plate (30) which acts as a second resonator. The second wall may include a hole which, with the second match plate, forms a second launch site for delivering microwave energy into the oven cavity, in which case the two holes are interconnected by a waveguide via which said microwave energy is supplied from at least one magnetron.
