Abstract
An arrangement for heating with the aid of microwave energy, comprising a microwave generator constructed to supply a waveguide, the waveguide having provided in one side surface thereof a dielectric plate through which microwave energy propagates. In accordance with the invention the arrangement includes at least two microwave generators (1, 2), each of which is arranged to supply a feed waveguide (3, 4). The feed waveguide (3, 4) is a power divider which is arranged to distribute the power input substantially equally to at least two applicators (7, 8; 9, 10) which extend at an angle to the feed waveguide, where each of the at least four applicators (7, 8; 9, 10) is provided on one side surface thereof with a dielectric plate (11, 12, 14) of the aforesaid kind. The applicators are positioned in relation to one another so that all dielectric plates (11, 12, 14) lie in one and the same plane.
