Action to the cross-polarization wave separator of one embodiment of the invention of such formation is illustrated with reference to the accompanying drawings.
The TE of circular waveguide
11The TE of mould and rectangular waveguide
10Mould has roughly the same electromagnetic field to distribute, and therefore, conversion is easy.As shown in Figure 1, as long as make circular waveguide slowly become rectangular waveguide, otherwise or make rectangular waveguide slowly become circular waveguide, just can carry out the transmission mode conversion.
Under the situation of present embodiment, rectangular waveguide 5,6 is vertically connected at circular waveguide 1, and therefore, the such method of Fig. 1 can not be used.Here utilize two kinds of similar character of mould to carry out conversion.
Under the situation of circular waveguide, it is that central portion is close, dredge the end that electromagnetic field distributes.And the distribution of the electromagnetic field of central portion is roughly identical with rectangular waveguide.In a word, circular waveguide considers that near the Electric Field Distribution the central portion get final product, and considers that central portion is neighbouring, can think the TE of circular waveguide
11The TE of mould and rectangular waveguide
10Mould is identical.Therefore, the end difference 3 of embodiments of the invention, as shown in Figure 5, electromagnetic field is by the height of each ladder of optimal selection, make between the planar portions of the seam of circular waveguide 1 and rectangular waveguide 5 or 6 and stepped portion 3 electromagnetic field couples takes place, thereby electromagnetic field is slowly crooked, finally bend to 90 degree.So when electromagnetic field was finished bending, modular transformation finished.
Also identical from waveguide 5 or 6 one sides' conversion.From rectangular waveguide 5 one sides, with rectangle TE as shown in the figure
10Mould 9 feeds promptly are transformed to circular TE expeditiously by the stepped portion 3 of cross electric wave separation transformation component 2
11Mould [9] 10 comes across the opening surface 1b of circular waveguide 1.
At this moment, because the effect electric wave of round metal pylon 4 is not and waveguide 6 couplings, therefore, all occur at the opening surface 1b of circular waveguide 1 from the electric wave of rectangular waveguide 5 feeds.
The following describes its reason.In Fig. 3, consider to have only the situation of the 1st polarized wave incident of direction of an electric field 7 from circular waveguide 1.Under round metal pylon 4 non-existent situations, electric field is owing to propagate everywhere in circular waveguide 1 inside, and a part is propagated with rectangular waveguide 6 couplings that the 2nd polarized wave is used, and outputs on the opening surface of the rectangular waveguide 6 that the 2nd polarized wave that can not occur originally uses.Under the situation that has round metal pylon 4, electric field is present between the inwall and round metal pylon 4 of rectangular waveguide 5 circular waveguide 1 nearby that the 1st polarized wave uses, so near the electric field 7 that does not have the 1st polarized wave the rectangular waveguide 6 that the 2nd polarized wave is used is rectangular waveguide 6 couplings of not using with the 2nd polarized wave.Thereby, rectangular waveguide 5 outputs that the 1st polarized wave 7 is all used from the 1st polarized wave.
Equally, at the rectangular waveguide of using from the 1st polarized wave 5 with rectangle TE
10Under the situation of mould incident, be transformed into the TE of circular waveguide in stepped portion 3
11The electric field of mould, because also propagation between rectangular waveguide 5 one sides' that the 1st polarized wave is used inwall and round metal pylon 4, the rectangular waveguide of using with the 2nd polarized wave 6 is not coupled.That is round metal pylon 4 has the effect of restriction electric field expansion.
And the electric wave that appears at the opening surface 1b of circular waveguide 1 is that direction of an electric field shown in Figure 3 is 7 the 1st plane polarized wave.Equally, in case from rectangular waveguide 6 feeds, all electric waves of feed-in promptly carry out outputing to after the modular transformation opening surface 1b of circular waveguide 1.But, at this moment become direction of an electric field shown in Figure 3 and be 8 the 2nd plane polarized wave.At this moment, criss-cross electric wave separation transformation component 2 plays a part to make waveguide 5,6 and circular waveguide 1 impedance matching with respect to central shaft with the part of waveguide 5,6 opposite sides.
Otherwise, at Fig. 3, be respectively 7,8 the 1st and the 2nd plane polarized wave in case inject direction of an electric field from the opening surface 1b of circular waveguide 1, this electric wave is promptly separated expeditiously by multi-ladder round metal pylon 4, direction of an electric field be 7 the 1st polarized wave all from rectangular waveguide 5 outputs, direction of an electric field is that 8 the 2nd polarized wave is all from rectangular waveguide 6 outputs.
Can recognize also that from Fig. 3 the inner surface of circular waveguide 1 is towards the open taper in the front of shaft core direction, the taper that criss-cross electric wave separation transformation component 2 and round metal pylon 4 progressively dwindle for the front towards shaft core direction.And rectangular waveguide 5,6 is open taper up.In view of the above, circular waveguide 1, rectangular waveguide 5, and the cross electric wave that comprises stepped portion 3 separates that transformation component 2 and round metal pylon 4 can utilize that setting paper front from figure inserts that above-below direction to Fig. 3 opens, upside is the slide cores of the metal die of formpiston, makes with the manufacture method monolithic molding of injection molding forming.Moulding material is suitable with materials such as aluminium.After also can processing criss-cross electric wave separately and separate transformation component 2 and round metal pylon 4, to be pressed into, screw is fixing etc. on the main body after method is installed in shaping with methods such as cut shapings.Stepped portion 3, round metal pylon 4 in example, be respectively 3 grades stepped, but decision as required also can be that 2 grades or 4 grades etc. are stair-stepping, details such as sum of series size do not limit.
Change above-mentioned circular waveguide into can use two orthogonal plane polarized waves square waveguide below.Change the square waveguide of the S1-S1 section that is parallel to Fig. 3 into, promptly have the both sides of the direction of an electric field 7 that is parallel to the 1st plane polarized wave and be parallel under the situation of square waveguide on both sides of direction of an electric field 8 of the 2nd plane polarized wave, have and the identical effect of effect that illustrates with Fig. 3～Fig. 5, this is readily appreciated that.
As mentioned above, the present invention at two orthogonal polarizations ripples of output on the position of circular waveguide peristome equidistance, can make the wave separator overall dimension dwindle with this in cross polarization wave separator.
Again, the round metal pylon and the criss-cross electric wave separation transformation component that separate two orthogonally polarized waves are disposed on the end face of circular waveguide terminal part, make circular waveguide, the round metal pylon, the cross electric wave separates transformation component and rectangular waveguide is tapered respectively, available injection molding forming processing makes whole wave separator integrally formed, by means of this, not only can save always necessary reflecting plate (conductor plate), the making of 90 degree phase-plates, various operations such as installation, and can remove the aberrations in property that rigging error causes when producing in batches and adjust operation, can obtain stable performance, and increase substantially production efficiency.
The present invention can implement with other various forms under the situation of not leaving its spirit and principal character.For example circular waveguide being changed into shown in Figure 2 is that the square waveguide on the limit of rectangle is exactly a tangible example with the direction of an electric field of the direction of an electric field of the 1st polarized wave and the 2nd polarized wave respectively.Therefore, all main points of the foregoing description are illustration only, rather than determinate explanation.Scope of the present invention is the described scopes of claims, is not subjected to the restriction of specification.Also have, the distortion or the change that belong to the equivalent scope of claims all belong in the scope of the present invention.
