Specific implementation mode
With reference to specific embodiment, the present invention is described in detail.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the common skill of this field
For art personnel, without departing from the inventive concept of the premise, several change and modification can also be made.
Fig. 1 is the heating device of the double antenna compensating heating device in a kind of restricted clearance provided by the invention, main to wrap
Containing shielding cavity 3 made of metal and built-in two radiation assemblies, respectively the first feed element 2,
One radiating element 4, the second feed element 7 and the second radiating element 6.
First feed element 2 and the second feed element 7 are usually by 50 ohm or coaxial cable and the company of 75 ohmages
Device composition is connect, the first feed element 2 and the second feed element 7 are respectively by the aperture and shielding cavity above shielding cavity
The first radiating element 4 and second radiating element 6 be separately connected.
First radiating element and the second radiating element are fixed on inside the shielding cavity, the first radiating element 4 and second
The installation site or angle of radiating element 6 are unrestricted, the type and connection of the first radiating element 4 and the second radiating element 6
Mode is unrestricted, is made of metal material with good conductivity, the ruler of 4 and second radiating element 6 of usual first radiating element
Very little different either positions are different or direction is different.
The effect of radiation assembly is to heat in high-power radio frequency or microwave energy to shielding cavity 3 negative
It carries.Zin1And Zin2The input impedance of the first radiating element 4 and the second radiating element 6, Z are corresponded to respectivelyin1And Zin2It is different defeated
Enter impedance, the matching aspect for generating source output terminal for power in this way there are more selections than single radiating element.First radiation
The input impedance difference of unit 4 and the second radiating element 6 also can be improved or improve the isolation between them, it is general can
With the position by adjusting radiation assembly, direction or size etc. optimize the isolation between them.
It is positioned in metallic shield cavity 3 and is heated by heat load 5, can be food, clothing, timber etc. by heat load 5
Deng being usually placed on and be lost on smaller insulation support plate by heat load.Insulation support plate is fixed in wire chamber, insulation branch
Fagging can be the materials such as glass or plastics.
Metallic shield cavity 3 is connected with the earth, and metallic shield cavity 3, which can also play, prevents signal power to be leaked to cavity
The effect of outside, the size and shape of shielding cavity are unrestricted.
Fig. 2 is the block architecture diagram of the double antenna compensating heating device in restricted clearance.Powerful radio frequency or microwave energy
Amount is needed before reaching heating device by circulator 1, and high-power energy enters circulator 1 by port Port1 first.
Circulator 1 is a kind of three port devices, it only allows signal there are one the flow direction in direction, and it can also be inverse clockwise that can be
Hour hands.Other two port of circulator 1 in the framework is sequentially connected the first feed element 2 and the second feed element respectively
The high-power signal of 7, Port1 ports can only pass to the first feed element 2 by circulator 1 and then reach the first radiation list
Member 4,4 reflected signal of the first radiating element can only pass to the second feed element 7 and then reach the second radiating element 6,
Second radiating element, 6 reflected signal can only pass to RF power fed-in source.Circulator 1 is used as one-way transmission device will
Power generating source output power signal preferentially pass to the first radiating element 4, if the input impedance of the first radiating element 4 with
The output impedance that power generates source mismatches, and 4 reflected signal of the first radiating element will pass to the second radiation list
Member 6, the second radiating element 6 again attempts to the radiant power signal that metallic shield cavity 3 is not entered on the first radiating element 4
It is radiated inside shielding cavity.Two radiating elements promote the efficiency of heating surface by heat load by way of mutually compensating for, simultaneously
Also widen the range of system heating load.The magnetic distribution of two radiating elements excitation is different can also to be improved by heat load
The uniformity of heating.
The ports Port1 are the importations of the energy of entire framework, this portion of energy is that radio frequency or microwave power are usual
It can be provided by solid-state power amplifier or by magnetron.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make a variety of changes or change within the scope of the claims, this is not
Influence the substantive content of the present invention.In the absence of conflict, the feature in embodiments herein and embodiment can be arbitrary
It is combined with each other.
