Abstract
A device and a method for microwave feeding of an oven cavity by means of a coupling slot (1) which is fed by a waveguide. The a-dimension of the waveguide is significantly larger than the effective a-dimension of the slot. The slot comprised a radiating main slot part (5) and slot extensions (6,7) projecting from it at its respective sides, which extension have a substantially smaller cross-dimension than the b-dimension of the main slot part.
