Antenna radiation heater for heating a material by using resonance

Abstract

The invention relates to an antenna radiation heating (2) to heat a matter by means of resonance with several surface antenna elements (3), each consisting of a carrier surface material (11) and a radiation coating (10) applied thereon which is delimited by two spaced electrical conductors (14, 15) in parallel, with electrical contact as antenna limiter and with which high-frequency electromagnetic radiation can be emitted. Furthermore, this antenna radiation heating (2) comprises a harmonic generator which is coupled to the two electrical conductors (14, 15) of a surface antenna element (3) for an excitation of the radiation coating (10) for emitting an oscillation spectrum within the range of molecular natural frequencies of the matter to be heated. In accordance with the invention, the radiation coating (10) is unilaterally applied to the carrier surface material (11) and forms an element front facing a matter to be heated. Furthermore, a contact protection layer (12) is applied to the radiation coating (10) which, on the one hand, electrically insulates the radiation coating (10) against contact and, on the other hand, enables the emission of the oscillation spectrum without or at least with only minor attenuation.
