Abstract
A microwave heating device and a method for operating a microwave heating device to heat a product inside a heating chamber includes at least two radiating portions that are adapted to radiate microwaves to the heating chamber and can be operated according to a plurality of operational configurations that differ in frequency or phase shift(s) between the radiated microwaves. A learning procedure can be executed by sequentially operating the radiating portions in several operational configurations for which energy efficiency data are calculated. An operating frequency can be selected via an algorithm that optimizes a mathematical function based on energy efficiency data. An operational configuration with a maximum energy efficiency at the selected operating frequency may be taken as a reference. A heating procedure can be executed by sequentially operating the radiating portions in operational configurations having the selected operating frequency and respective phase shift(s) chosen around the respective phase shift(s) of the reference operational configuration.
