Microwave treatment device
A microwave treatment device includes a treatment chamber, in which an object to be treated can be arranged, and a microwave emission device, by which microwave radiation can be radiated into the treatment chamber or emitted therein. The microwave emission device includes at least one array antenna with a plurality of individual emitters and a microwave control device which can be used to specify an emission characteristic for each individual emitter of the at least one array antenna. A phase and/or amplitude of the microwave emission can be specified for each individual emitter by the microwave control device. A phase and/or an amplitude of the microwave emission can be specified for each individual emitter by the microwave control device. Furthermore, a frequency of the microwave emission can be specified within a frequency range for each individual emitter by the microwave device.
1 . A microwave treatment device ( 1 ), comprising:
a microwave emission device, by which microwave radiation can be radiated into a treatment chamber ( 2 ) or emitted therein,
wherein the microwave emission device comprises
at least one array antenna ( 7 ) having a plurality of patch antennas ( 8 ), and
a microwave control device ( 9 ) by which an emission characteristic can be specified for each individual emitter ( 8 ) of the at least one array antenna ( 7 ), and
wherein a phase of a microwave emission can be specified for each patch antenna ( 8 ) by the microwave control device ( 9 ),
wherein the microwave control device ( 9 ) comprises a phase shifter for each patch antenna, for changing and adjusting the phase of an electromagnetic wave supplied to the respective patch antenna, and
wherein the treatment chamber ( 2 ) comprises
an inlet opening and an outlet opening for introducing and removing an object ( 5 ) to be treated, and
a conveying device by which the object ( 5 ) to be treated can be conveyed through the inlet opening into the treatment chamber ( 2 ) and can be conveyed through the outlet opening and out of the treatment chamber ( 2 ).
2 . The microwave treatment device ( 1 ) according to claim 1 ,
wherein an amplitude of the microwave emission can be specified for each patch antenna ( 8 ) by the microwave control device ( 9 ).
3 . The microwave treatment device ( 1 ) according to claim 1 ,
wherein a frequency of a microwave emission can be specified within a frequency range for each patch antenna ( 8 ) by the microwave control device ( 9 ).
4 . The microwave treatment device ( 1 ) according to claim 1 ,
wherein the at least one array antenna ( 7 ) is arranged inside a housing ( 3 ) that is made of an electrically conductive material and surrounds the treatment chamber ( 2 ).
5 . The microwave treatment device ( 1 ) according to claim 1 ,
wherein a plurality of array antennas ( 7 ) are arranged relative to the treatment chamber in such a way that an object ( 5 ) to be treated can be irradiated from different directions by the microwave radiation emitted by one array antenna ( 7 ) in each case.
6 . The microwave treatment device ( 1 ) according to claim 1 ,
wherein an antenna lens device is arranged between the at least one array antenna ( 7 ) and an object ( 5 ) to be treated, by means of which antenna lens device microwave radiation emitted by the array antenna ( 7 ) or by at least one patch antenna ( 8 ) of the array antenna ( 7 ) can be deflected or focused.
7 . The microwave treatment device ( 1 ) according to claim 1 , further comprising
at least one anti-leakage array antenna which is oriented and actuatable such that microwave radiation of the at least one array antenna ( 7 ) emerging through the inlet opening and/or through the outlet opening undergoes destructive superposition, and an emerging intensity of the microwave radiation is reduced as a result.
