Abstract

An antenna for emitting microwave radiation into a cavity, and configured to emit microwave within a first frequency range of 400-500 MHz and a second frequency range of 2.4-2.5 wherein the antenna comprises a cylindrical portion 101, wherein the length of the cylindrical portion is within a range of −8% and +14% of 119 mm, and wherein the outer diameter of the cylindrical portion is within a range of −8% and +14% of 60 mm; and a frustoconical portion contiguous with the cylindrical portion, wherein the length of the frustoconical portion is within a range of −8% and +14% of 80 mm, wherein the outer diameter of the frustoconical portion tapers from a diameter within a range of −8% and +14% of 60 mm to a diameter within a range of −8% and +14% of 20 mm. Apparatus and method for the processing (drying and/or cooking) of foodstuffs and other materials using dual frequency, microwave radiation utilising solid-state power generators. The apparatus uses both an antenna and a waveguide for transmitting microwave radiation to a processing chamber. A first microwave generator generates microwave radiation having a first frequency, wherein the first frequency is substantially between 2.4 and 2.5 GHz and a second microwave generator generates microwave radiation at a second frequency, wherein the second frequency is substantially between 400-500 MHz. A microwave waveguide disposed in or at the chamber is configured to emit the microwave radiation from the first microwave generator into the chamber and an antenna disposed in or at the chamber is configured to emit the microwave radiation from the second microwave generator into the chamber.
