Description

The present invention relates to a high-frequency phase shifter group with at least two stacked high-frequency phase shifters, which are arranged in at least one housing.

High-frequency phase shifters are used in antenna technology to change the phase position of a signal with which the radiators of an antenna array are supplied. In particular, high-frequency phase shifters serve for the electrical reduction of the radiation pattern.

High-frequency phase shifters usually have a rotatably mounted pickup, which is electrically coupled to a feed line via a coupling point arranged in the region of its axis of rotation. The customer contacted depending on its rotational position a stripline section at different positions. Depending on the rotational position of the customer thereby the signal path and thus the phase angle are changed. In this case, the customer can be designed in particular pointer-shaped, and optionally a plurality of stripline sections, which at different distances to the axis of rotation the customer are located, contact. As a result, a high-frequency phase shifter can drive a plurality of radiators, each with different phase shifts. Such a high-frequency phase shifter is for example from the EP 1 208 614 B1 known.

For larger antenna arrays, however, it is often necessary to use several separate high-frequency phase shifters, which, however, are adjusted synchronously. In order to achieve a particularly compact arrangement of the high-frequency phase shifter, they can be stacked one above the other. In order to shield the high-frequency phase shifters to the outside, they are usually arranged in a housing. In order to adjust the customers of the high-frequency phase shifter synchronously, these are mechanically coupled together in known high-frequency phase shifter assemblies in the stack by a common axis of rotation. Upon rotation of the common axis of rotation, the takers thereby rotate synchronously.

For electrical decoupling of the high-frequency phase shifters usually a housing plate is provided in the stack between the high-frequency phase shifters, which, however, must have an axle bushing in the region of the axis of rotation. As a result, the shielding of the high-frequency phase shifter with each other but deteriorated just where the signal is fed from the supply lines in the customer. This has a negative effect on the electrical decoupling of the high frequency phase shifters. Decisive for the decoupling of the two phase shifters is the distance between the two phase shifters and the diameter of the Achsdurchführung and the material of the axle feedthrough, where it was partially necessary in the art to achieve a sufficient decoupling to increase the distance of the phase shifter in the stack. Due to the space limitations and the mechanical requirements of the common axis of rotation, the decoupling of the high-frequency phase shifter in the stack therefore can not be arbitrarily improved.

The object of the present invention is therefore to further develop a high-frequency phase shifter assembly having at least two stacked phase shifters so that the decoupling of the high-frequency phase shifters in the stack is improved.

This object is achieved by a high-frequency phase shifter assembly according to claim 1 and a stackable high-frequency phase shifter according to claim 12.

Advantageous embodiments of the present invention are the subject of the dependent claims.

The present invention comprises a high-frequency phase shifter assembly with at least two stacked high-frequency phase shifters, which are arranged in at least one housing, wherein between the high-frequency phase shifters in the stack at least one housing plate is provided. The high-frequency phase shifters each have a rotatably mounted pickup, which is electrically coupled via a arranged in the region of its axis of rotation coupling point with a feed line. The customers of the high frequency phase shifters are mechanically coupled for the synchronous adjustment of the high frequency phase shifters. According to the invention, provision is made for the mechanical coupling of the pickups of the high-frequency phase shifters to take place via a coupling arrangement spaced from the axes of rotation of the pickups.

According to the invention, the mechanical coupling is no longer carried out by a common axis of rotation of the frequency phase shifter, but via a spatially separate from the axes of rotation coupling arrangement. This makes it possible to completely separate the axes of rotation of the individual pickups and also to allow improved shielding in the area of the rotary axes by the housing plate arranged between the high-frequency phase shifters.

Characterized in that no continuous axis of rotation of the pickup is provided in the stack, but the mechanical coupling is spaced from the axes of rotation, an improved decoupling is possible according to the invention. The high-frequency phase shifters preferably have an electrical decoupling of at least 25 dB, more preferably of at least 29 dB, more preferably of at least 35 dB, and more preferably of at least 40 dB.

According to the invention, therefore, the distance of the phase shifter can be reduced in the stack, since this is no longer decide for the decoupling in the same way as in the prior art. In this case, the spacing of the phase shifters in the stack can be less than 17 mm, preferably less than 15 mm, more preferably less than 12 mm.

Since there is no longer a continuous axis of rotation of the pickups, the housing plate arranged in the stack between the high-frequency phase shifters no longer has to have a passage opening in the area of the rotation axis for the rotation axis, so that this area of the housing plate can be improved with regard to its decoupling properties. Breakthroughs, for example in the form of inspection openings, can definitely be provided in the area of the rotary axes. However, these can be smaller than the axle bushings required in the prior art.

Preferably, the at least one housing plate arranged in the stack between the high-frequency phase shifters in the region of the axes of rotation of the pickups has no openings whose outer circumference is greater than 1/8 of the minimum wavelength of the signals with which the high-frequency phase shifter assembly is operated. More preferably, the housing plate in the region of the axes of rotation of the pickup on no breakthroughs whose outer circumference is greater than 1/10 and more preferably greater than 1/15 of the minimum wavelength of the signals. The outer circumference is of particular importance for the electrical decoupling due to induced circulating currents around the edges of the opening.

The housing plate therefore preferably has no openings relevant to the electrical decoupling in the area of the axes of rotation. In particular, the apertures should not significantly affect the shielding, even for the minimum wavelength of the signals with which the high frequency phase shifter assembly is operated. In one possible embodiment, the housing plate in the region of the axes of rotation at all no openings.

In the high-frequency phase shifter assembly according to the invention, the high-frequency phase shifters can be stacked on top of one another such that the axes of rotation of the respective pickups run parallel to one another and are preferably aligned with one another. This allows a particularly compact arrangement. Even with such an aligned arrangement of the axes of rotation arranged in the region of the axes of rotation coupling points for coupling the signals in the customers are electrically decoupled from each other, since the intermediate housing plate prevents electrical coupling.

In a preferred embodiment, the pickups of the high-frequency phase shifters are designed to be pointer-shaped and have one or more coupling points with which they are electrically coupled to one or more stripline sections. The ends of the stripline sections can be connected to radiators, so that by turning the pickup, the path length of the signals to the radiators and thus the phase position is shifted. Preferably, the one or more stripline sections extend concentrically about the axis of rotation of the pickup. If a plurality of stripline sections are provided, they usually have a different radial distance from the rotation axis, so that the adjustment of the pickup leads to different phase shifts for the individual stripline sections. The pickup itself can also be designed as a pointer-shaped, rotatable stripline section, wherein in the case of several stripline sections, the coupling points of the pickup to the stripline sections are successively arranged on the pointer-shaped stripline section.

The coupling between the feed line and the pickup in the region of the coupling point is preferably capacitive. In particular, the pickup in the region of the axis of rotation may have an annular line section, which is separated by a dielectric from a likewise annular line section connected to the feed line. The coupling between the pickup and the stripline sections is preferably capacitive.

The individual high-frequency phase shifters in the stack can be configured as described in US Pat EP 1 208 614 B1 is known.

The high-frequency phase shifter assembly according to the invention can in a first embodiment have a common housing in which at least two high-frequency phase shifters are stacked one above the other. In this case, the at least two high-frequency phase shifters are separated by an intermediate plate of the housing. If more than two high-frequency phase shifters are provided, at least one intermediate plate is provided in each case between the individual high-frequency phase shifters.

In an alternative embodiment, the high-frequency phase shifters may each have their own housing, wherein the housing of the high-frequency phase shifter for stacking the high-frequency phase shifter assembly are stacked and interconnected. This allows the flexible provision of high-frequency phase shifter assemblies with different numbers of high-frequency phase shifters, since, depending on the requirement, a corresponding number of high-frequency phase shifters, each having its own housing, are stacked on top of each other. The housing of the individual high-frequency phase shifters have in the region of the axis of rotation of the pickup on at least one side no Achsdurchführung and thus also allows a good electrical decoupling of the individual high-frequency phase shifter in the stack.

By achieved by the lack of continuous axis of rotation improved decoupling the individual high-frequency phase shifter can be arranged with a smaller distance from each other in the stack. In this case, the distance between the housings of stacked high-frequency phase shifters may be less than 11 mm, preferably less than 8 mm, more preferably less than 5 mm, more preferably less than 2 mm. Furthermore, it can be provided that the housing of the high-frequency phase shifter in the stack, if appropriate, rest on one another with the interposition of an insulating layer. As a result, the height is reduced.

Regardless of a common housing for the high-frequency phase shifter assembly or their own housing for the high-frequency phase shifter or the housing are preferably designed as a closed housing. Such a closed housing preferably has a bottom plate and a cover plate, which preferably extend perpendicular to the axis of rotation of the pickup, and side walls which extend between the bottom plate and the cover plate and close the housing. Of course, however, certain openings may be provided in the individual plates or walls. However, the openings are preferably less than 20% of the surface of the housing, furthermore preferably less than 10%. In one possible embodiment, the side walls may be formed as angled portions of a plate forming the cover plate, and be connected to a plate forming the bottom plate, for example via fastening tabs. The housing is preferably made of metal or has a metallic coating. For example. can be used instead of a metal housing while a plastic housing with a metallic surface, in particular a housing made of galvanized plastic.

The specific embodiment of the coupling arrangement, via which the mechanical coupling of the pickups of the individual high-frequency phase shifters takes place in the stack, is initially arbitrary according to the present invention. The decisive factor here is that the mechanical coupling is not due to a common Is the axis of rotation of the customer, but by a spaced apart from the axes of rotation coupling arrangement to allow the separation of the axes of rotation through the housing plate.

In one possible embodiment, the coupling arrangement can be arranged wholly or partly outside the housing (s). In this case, the axis of rotation of the pick-up is preferably led out of the housing on one side and communicates there with the coupling arrangement. On the other hand, on the other hand, the axis of rotation is preferably not guided out of the housing, but separated by a housing plate at least partially from the next axis of rotation.

The coupling arrangement can be arranged in an alternative embodiment wholly or partly within the housing or the housing. In this case, the axis of rotation of the pickup is preferably not led out of the housing at all, but is in communication with the coupling arrangement within the housing. Possibly. However, the axis of rotation of one or more customers may also be led out at a disposed within the housing coupling assembly on one side of the housing, and serve as a drive axis for the high-frequency phase shifter assembly.

• In einer ersten möglichen Ausführungsform erfolgt die mechanische Kopplung der Abnehmer der Hochfrequenz-Phasenschieber durch ein Getriebe. Das Getriebe weist dabei bevorzugt mindestens eine versetzt zu den Drehachsen der Abnehmer verlaufende Verbindungswelle auf. Bevorzugt verläuft die Verbindungswelle dabei parallel zu den Drehachsen, jedoch in einem gewissen Abstand zu diesen.

In the following, possible embodiments of mechanical coupling arrangements according to the present invention will now be described in more detail:

• In a first possible embodiment, the mechanical coupling of the pickup of the high-frequency phase shifter is effected by a transmission. The transmission preferably has at least one offset to the axes of rotation of the customer connecting shaft. Preferably, the connecting shaft is parallel to the axes of rotation, but at a certain distance from them.

In each case first transmission elements are preferably non-rotatably connected with the consumers, which are connected to second transmission elements which are connected to the connecting shaft are arranged, cooperate to transmit a rotational movement between the connecting shaft and the customers. In particular, the gear elements may be gearwheels or gearwheel segments. The first and second gear elements can be arranged so that they mesh directly with each other. Optionally, however, other transmission elements between the first and second transmission element may be interposed.

According to the invention, the second gear elements are coupled together by the connecting shaft and thus permit a mechanical coupling of the pickups, without the axes of rotation of the pickup being directly coupled to one another. For unlike in the prior art so do not have the customers on a common axis of rotation, but the spaced from the axis of rotation of the pickup second gear elements.

The transmission, which is used for the mechanical coupling of the individual consumers of the high-frequency phase shifter, can be arranged completely outside the housing of the high-frequency phase shifter assembly or the housing of the individual high-frequency phase shifters in one possible embodiment. For this purpose, the axis of rotation of the pickup can each be led out of the housing on one side and connected there in a rotationally fixed manner to the first gear element. The first transmission elements, the second transmission elements and the connecting shaft can thus be arranged outside the respective housing.

Preferably, however, the transmission is at least partially disposed within the housing of the high-frequency phase shifter assembly or the respective housing of the high-frequency phase shifter. In particular, at least the first and the second gear elements can be arranged within the housing or the housing.

In this case, the connecting shaft is preferably guided through an axle bushing through the at least one housing plate arranged between the high-frequency phase shifters. Although it must be provided for the connecting shaft of the second gear elements in the housing plate, which separates the high-frequency phase shifter from each other in the stack, a breakthrough. However, according to the invention, this is no longer arranged in the region of the axis of rotation of the pickup and the coupling point arranged there for electrical coupling of the pickup, but removes it, so that the axis breakdown has no negative influence on the decoupling of the high-frequency phase shifters. The connecting shaft is preferably arranged on a side opposite the stripline sections with respect to the axis of rotation of the pickup.

In one possible embodiment, the high-frequency phase shifter assembly has a common housing, wherein the connecting shaft extends within the housing. Preferably, the coupling arrangement is thus completely within the housing.

In order to operate the high-frequency phase shifter assembly or to adjust the customers synchronously, the connecting shaft or at least one of the axes of rotation of the consumer or a further drive shaft may be guided out of the housing.

According to a further preferred embodiment of the present invention, the high-frequency phase shifters each have their own housing, wherein the housing for stacking the high-frequency phase shifter assembly are stacked and interconnected. In this case, a first transmission element is disposed within the housing of a high-frequency phase shifter, which is rotatably connected to the consumer, and which cooperates with a second, also arranged in the housing of the high-frequency phase shifter gear element. The first and the second gear element are preferably rotatably mounted in or on the housing. In particular, the first gear element can be rotatably mounted together with the customer.

In particular, the second transmission elements can be arranged offset next to the first transmission element and preferably comb with this. Preferably, the axes of rotation of the first and second gear element are parallel.

The second, arranged in the respective housings gear elements can be coupled to each other according to the invention. The second gear elements of the stacked high-frequency phase shifters are preferably connected to one another via a connecting shaft guided through axle bushings in the respective housings.

In a first possible embodiment, the second transmission elements can be connected to each other by a continuous connecting shaft passing through shaft openings in the second transmission elements. As a result, the desired number of high-frequency phase shifters are stacked on each other and the second transmission elements are then mechanically coupled by pushing the connecting shaft through the shaft openings of the second transmission elements.

In an alternative embodiment, the second gear elements may each have connecting shaft sections which are connected to a connecting shaft section of a second gear element of a high-frequency phase shifter arranged thereunder or above. This also allows easy stacking of any number of high frequency phase shifters. Preferably, the connecting shaft sections can be connected to one another via a plug connection and / or detachably.

In this case, the housing of the high-frequency phase shifter preferably has openings for the connection shaft on both sides of the axis of rotation of the second transmission elements.

In accordance with the invention, a plurality of high-frequency phase shifters of identically constructed construction, at least with regard to the housing and the connection of the second transmission elements, can be combined to form a high-frequency phase shifter assembly according to the present invention. The housings of the individual high-frequency phase shifters can have connection points, for example in their base plate, via which the individual high-frequency phase shifters arranged in the stack can be connected to each other, for example, by passing connecting elements.

In one possible embodiment of the present invention, the transmission ratio for each high-frequency phase shifter may be equal to the high-frequency phase shifter assembly, so that upon movement of the transmission, identical displacement of the high-frequency phase shifter results.

In an alternative embodiment, however, the transmission may also have different ratios for the respective high-frequency phase shifters, such that a different adjustment of the individual high-frequency phase shifters results during a movement of the transmission. Although the high-frequency phase shifters in the stack are thus still moved synchronously, but with different adjustment angles, so that there are correspondingly different phase shifts.

As just described, a transmission can thus be used as a mechanical coupling arrangement for coupling the pickups of the high-frequency phase shifters in the stack. However, the invention is not limited to this embodiment.

On the other hand, in an alternative embodiment, the mechanical coupling of the pickups of the high-frequency phase shifters can take place via a lever arrangement. Preferably, the levers are in each case connected in a rotationally fixed manner to the pickups and extend away from the axis of rotation of the pickup so that they can be coupled together in a region which is spaced apart from the axis of rotation. To move the lever can be provided a linkage be. The coupling of the levers of each high-frequency phase shifter can be done either indirectly via the linkage, or directly, for example via a connecting rod.

The coupling between the linkage and the levers is preferably carried out via one or more link guides, in which or in which one or more driving pins are guided. A displacement of the linkage in a direction tangential to the axis of rotation of the pickup thereby leads to a rotational movement of the lever and the pickup, wherein the guide pin moves along in the slotted guide. The slotted guide can preferably be designed as a slot. In one possible embodiment, the guide pin is arranged on the lever and is guided in a link guide arranged on the linkage.

In a first possible embodiment, the levers of the individual high-frequency phase shifters can have the same length or be connected to the linkage in the same way, so that an identical adjustment of the high-frequency phase shifters results during a movement of the linkage. If the coupling of the levers with the linkage in each case separately via its own slotted guide, so the individual levers associated guide pins preferably have the same distance from the axis of rotation of the lever and thus of the pickup, so that each results in the same lever arm. Alternatively, it is conceivable to connect the individual levers directly to one another rigidly, so that only one guide pin and one slide guide can be used to adjust a plurality of levers and thus a plurality of high-frequency phase shifters.

In an alternative embodiment, the levers of the individual high-frequency phase shifters may have different lengths and / or be separately connected to the linkage, so that different movements of the individual high-frequency phase shifters result during a movement of the linkage. Preferably, the drive pins assigned to the individual levers have different distances from the axis of rotation of the levers or the customer, so that there are different lever arms. In a linear adjustment of the linkage, this results in each case a different rotational movement of the lever and thus the customer. As a result, the customers are still adjusted synchronously, but produce different phase shifts.

The levers assigned to the respective users preferably run in a plane which is perpendicular to the axis of rotation of the pickup. Preferably, the levers extend radially to the axis of rotation of the pickup.

In a first possible embodiment, the levers can be guided out of the housing on the opposite side of the axis of rotation through a slot of the housing. This results in a low height.

On the one hand, such an arrangement is conceivable if all the high-frequency phase shifters in the stack have a common housing. In this case, the common housing has a corresponding number of slots in a corresponding side wall, through which the levers are guided to the outside.

However, such an embodiment is also conceivable if the individual high-frequency phase shifters each have their own housing. In this case, the housing of each high-frequency phase shifter has a corresponding slot through which the lever is guided to the outside.

In an alternative embodiment, however, the axes of rotation of the pick-up can also be led out of the housing on one side and the levers can each be connected to the axis of rotation outside the housing. On the opposite side of the axes of rotation, however, a housing plate is provided, which separates the individual axes of rotation.

In an arrangement with only two stacked phase shifters, the axis of rotation of the pickup at the upper high-frequency phase shifter can be guided upwards, at the bottom down out of the housing.

Alternatively, an arrangement is conceivable in which each high-frequency phase shifter has its own housing, wherein the axes of rotation are each led out of the housing on the same side. In this case, the lever extends at least in the interior of the stack between the cover plate of the housing of a phase shifter and a bottom plate of another phase shifter.

In addition to the above-described high frequency phase shift assemblies having a plurality of stacked high frequency phase shifters, the present invention further includes high frequency stackable phase shifters for providing such high frequency phase shifter assemblies.

Such a stackable high-frequency phase shifter has its own housing, in which a rotatably mounted pickup is arranged, which is electrically coupled via a arranged in the region of its axis of rotation coupling point with a feed line. The high-frequency phase shifter in this case has a coupling element which allows a spaced from the axis of rotation of the pickup coupling the movement of the pickup of the high-frequency phase shifter with the movement of a pickup of another high-frequency phase shifter. By stacking two or more of such stackable high frequency phase shifters, a high frequency phase shifter group according to the present invention as described above can be provided.

The stackable high-frequency phase shifter can be designed as described above with regard to the high-frequency phase shifter assembly.

In particular, the coupling point can be electrically shielded by the housing at least to one side of the axis of rotation to the outside. Furthermore, two stacked high-frequency phase shifters preferably have an electrical decoupling of at least 25 dB, further preferably at least 29 dB, more preferably at least 35 dB, further preferably at least 40 dB.

Furthermore, it can be provided that the housing in the region of the axis of rotation of the pickup has at least on one side of the axis of rotation no openings whose outer circumference is greater than 1/8 of the minimum wavelength of the signals with which the high-frequency phase shifter is operated. Preferably, the housing in the region of the axis of rotation of the pickup at least on one side of the axis of rotation out no breakthroughs whose outer circumference is greater than 1/10 and more preferably greater than 1/15 of the minimum wavelength of the signals.

In a possible embodiment, the housing in the stacking direction may have a thickness of less than 17 mm, preferably less than 15 mm, more preferably less than 12 mm.
Furthermore, a first transmission element can be arranged within the housing, which is rotatably connected to the consumer and cooperates with a second transmission element also arranged in the housing. In this case, the second transmission element preferably allows mechanical coupling with other high-frequency phase shifters in stacks.

In particular, the housing can have an axle bushing for a connecting shaft on both sides in the area of the second transmission element. For this connecting shaft, the second gear elements of the individual high-frequency phase shifters and thus their customers can be mechanically coupled to each other without the axes of rotation of the customer would have to be connected directly.

In one possible embodiment, the second gear element in this case has a shaft opening through which the connecting shaft can be pushed. Alternatively, the second transmission element may have a connection shaft section, which is connectable to a connection wave portion of a high frequency phase shifter disposed above or below. Preferably, the connecting shaft sections can be connected to one another via a plug connection and / or detachably.

As an alternative to the transmission, the high-frequency phase shifter may have a lever, via which the pickup is movable. The lever is rotatably connected thereto with the axis of rotation of the customer.

In a first possible embodiment, the lever can be connected in the housing with the consumer and be led out on the side opposite the customer side of the axis of rotation through a slot out of the housing.

Alternatively, the axis of rotation of the pickup may be led out of the housing on one side and the lever outside the housing connected to the axis of rotation.

The housing of a stackable high-frequency phase shifter according to the invention may comprise, for example, a base plate, a cover plate and side walls. Cover plate and side walls can be formed by a contiguous, correspondingly curved metal plate. The bottom plate may have connection points which allow connection of the individual high-frequency phase shifters in the stack. In particular, connecting openings may be provided through which connecting elements which connect the individual high-frequency phase shifters to one another pass through.

The high-frequency phase shifter according to the invention is preferably designed such that it can be stacked with further high-frequency phase shifters, at least with respect to the housing identically designed, in particular so that the axes of rotation of the pickups are arranged parallel to each other and preferably aligned with each other. If the mechanical coupling takes place via second transmission elements, as described above, preferably also their axes of rotation are aligned.

The present invention further includes a high frequency antenna having a high frequency phase shifter assembly as described above and a plurality of radiators drivable via the phase shifter assembly. The emitters are preferably connected to the high-frequency phase shifters of the high-frequency phase shifter assembly according to the invention such that the radiation pattern of the antenna can be electrically aligned and, in particular, lowered by adjusting the high-frequency phase shifter assembly. In particular, it may be a mobile radio antenna.

The high-frequency phase shifter assembly according to the invention can be manually operated in a first embodiment. For example, an adjusting element, e.g. a knob can be provided, via which the high-frequency phase shifter can be adjusted. Alternatively or additionally, the high-frequency phase shifter assembly can also be adjusted by motor. Preferably, a corresponding drive motor is provided for this purpose.

In the first embodiment, in which a transmission is used as a mechanical coupling element, the adjusting element or the drive motor can be in communication with the connecting shaft, an axis of rotation of a pickup or an additional drive axle. In the second embodiment, in which a lever arrangement is used as a coupling arrangement, the adjusting element or the drive motor preferably moves a linkage coupled to the levers.

The present invention will now be described in more detail with reference to embodiments and drawings.

In Fig. 1 is the basic structure of a high-frequency phase shifter assembly according to the invention, the preferred used high-frequency phase shifter and the basic principle of the inventive electrical decoupling of high-frequency phase shifter in the stack shown in more detail.

In the Fig. 1 shown high-frequency phase shifter assembly has a first high-frequency phase shifter 1 and a second high-frequency phase shifter 2, which are arranged stacked. Each of the high-frequency phase shifters 1, 2 in this case has a rotatably mounted pickup 5 with a corresponding axis of rotation 4. The pickup 5 is in the region of the axis of rotation 4 via an in Fig. 1 not shown coupling point electrically coupled to a feed line. Preferably, the coupling takes place capacitively.

The pickup 5 is designed like a pointer and has a coupling point 6, with which it is electrically coupled to a stripline section 7. Again, the coupling is preferably capacitive. One or both ends of the stripline section 7 form connection points for radiators, which are supplied with a signal by the high-frequency phase shifter. The stripline section 7 is preferably arranged in an arcuate manner about the axis of rotation 4 of the high-frequency phase shifter. By rotating the pickup 5 thus changes the position of the coupling point 6 with respect to the ends of the stripline section 7 and thus the path length, which must cover a signal via the pickup 5 and the stripline section 7 to one of the terminals of the radiator. Over the changed path length the phase position is changed.

At the in Fig. 1 In the embodiment shown, the pickup 5 has only one coupling point 6 and one stripline section 7. However, several coupling points 6 may be provided for a plurality of stripline sections 7. In this case, the stripline sections are preferably arranged at a different spacing from the axis of rotation of the high-frequency phase shifter, and the coupling points provided for the stripline sections are arranged one behind the other in the extension direction of the pickup. As a result, multiple radiators can be controlled synchronously, but with different phase shifts.

The high-frequency phase shifters 1 and 2 in the stack are arranged one above the other so that the axes of rotation 4 of the high-frequency phase shifter 1 and 2 are aligned. This allows a particularly compact arrangement of the high-frequency phase shifter. Unlike in the prior art, however, the pickups 5 have no common mechanical axis of rotation. As a result, the high-frequency phase shifters 1 and 2 in the region of the axes of rotation 4 of their customers 5 are electrically decoupled from one another by a housing plate 10, so that the coupling points of the respective feed lines arranged in the region of the axes of rotation are electrically decoupled. In this case, the housing plate 10 preferably has no openings or only small openings in the area of the axis of rotation 4, so that they do not affect the electrical shielding in the maximum frequency range of the phase shifter assembly and thus at minimum permissible wavelengths. For example, the openings - if present - can be chosen so small that the high-frequency phase shifters have a decoupling of at least 25 dB, preferably of at least 35 dB. The ends of the axes of rotation 4 are mounted to the housing plate 10 in each case via a bearing 8.

The high-frequency phase shifter assembly in this case has a closed housing 3 to electrically shield the high-frequency phase shifter assembly and the individual high-frequency phase shifters 1 and 2 in the stack.

At the in Fig. 1 shown embodiment, the high-frequency phase shifter 1 and 2 in this case a common housing 3, and are electrically decoupled from each other by the designed as an intermediate plate housing plate 10. Alternatively, however, each high-frequency phase shifter may have its own housing, wherein the individual high-frequency phase shifter then stacked with their housings and their housing are connected to each other.

In order to adjust the axes of rotation while synchronous despite the separation by the housing plate 10, it requires an in Fig. 1 not shown, spatially separated from the axes of rotation 4 mechanical coupling arrangement.

In this case, the high-frequency phase shifter assembly also comprise more than two stacked high-frequency phase shifter, which are then separated from each other in the region of the axes of rotation by housing plates and their customers are mechanically coupled by a spaced apart from the axes of rotation coupling arrangement.

The mechanical coupling can be at the in Fig. 1 illustrated embodiment outside of the housing 3 done. The axis of rotation 4 of the upper phase shifter 1 is guided above a passage 9 out of the housing 3, and the axis of rotation 4 of the lower phase shifter 2 through a lower feedthrough 9. The mechanical coupling arrangement can therefore attack outside of the housing 3 in each case on the axes of rotation 9 and couple them outside the housing.

The coupling can be done for example via an outside of the housing arranged gear, or as based on FIGS. 7 and 8th explained in more detail on a arranged outside the housing lever assembly.

However, the coupling arrangement can also be arranged wholly or partly in the interior of the housing, as will be explained in more detail below.

The following are based on the FIGS. 2 to 8 Embodiments of high-frequency phase shifter assemblies and thereby used coupling arrangements described in more detail. The basic structure of these high-frequency phase shifter assemblies and / or the high-frequency phase shifter used in this case corresponds to that already with reference to FIG Fig. 1 explained structure.

In Fig. 2 a first embodiment of a high frequency phase shifter assembly with a gear 11 is shown as a coupling arrangement for the axes of rotation of the pickup 5. The gear 11 in this case has a connecting shaft 12, which is arranged at a distance from the axes of rotation 4 of the pickup 5 and provides for an indirect mechanical coupling of the axes of rotation. The transmission further comprises non-rotatably connected to the customers 5 in communication first gear elements 14, which cooperate with each rotatably mounted on the connecting shaft 12 second gear elements 15. In the exemplary embodiment, the first gear elements 14 and the pickup 5 are arranged together on the respective axis of rotation 4. The gear elements 14 and 15 may in particular be gears or gear segments act. In the exemplary embodiment, the first gear elements 14 assigned to the pickups 5 mesh directly with the second gear elements 15 assigned to the connecting shaft 12.

In the in Fig. 2 Shown embodiment, the transmission 11 and thus the coupling arrangement is disposed completely within the housing 3. For this purpose, the connecting shaft 12 is mounted in the housing 3 at bearings 13. In this case, the housing plate 10 arranged between the phase shifters 1 and 2 has an axle bushing 17 for the connecting shaft 12. The connecting shaft 12 and thus the axle bushing 17 is arranged in the exemplary embodiment with respect to the axis of rotation 4 on the opposite side of the pickup 5 and the stripline sections 7 and thus in a region in which no signal-carrying sections of the phase shifter. The shaft bushing 17 therefore has no negative influence on the decoupling.

The adjustment of the phase shifter takes place at the in Fig. 2 shown embodiment of one of the axes of rotation 4 of the takers, which are led out in each case via a passage 9 on one side of the housing 3. However, it would be sufficient if only one axis of rotation of a high-frequency phase shifter would lead out of the housing, since the other high-frequency phase shifter is in any case mitverstellt via the gear 11.

Fig. 3 shows a further embodiment of a high-frequency phase shifter assembly according to the invention, which in its basic structure essentially the in Fig. 2 shown embodiment is similar. Unlike there, however, the adjustment is not done via one of the axes of rotation 4 of the phase shifter, but via the connecting shaft 12 of the transmission. For this purpose, the connecting shaft 12 is led out of the housing 3 via a bushing 16. On the other hand, the axes of rotation 4 of the phase shifters 5 are respectively mounted on bearings 8 on or in the housing 3 on both sides and are not led out therefrom.

At the in Fig. 3 In the embodiment shown, the connecting shaft 12 is also led out of the housing 3 on the underside via a bushing 18. This allows, if appropriate, to arrange further high-frequency phase shifters in the stack and also to drive them via the connecting shaft. Optionally, however, the second implementation 18 could also be dispensed with.

In Fig. 4 is another variant of in Fig. 2 shown basic structure shown. Again, the mechanical coupling via a transmission with a connecting shaft 12, which runs parallel to the axes of rotation 4 of the pickup 5. Furthermore, here too the adjustment takes place via the outwardly guided axes of rotation 4 of the customers. Unlike the in Fig. 2 and 3 In the exemplary embodiments shown in which the first and second gear elements 14 and 15 each have an outer toothing, are in the in Fig. 4 shown embodiment, however, first gear elements 14 used with an internal toothing, which cooperate with second gear elements 15 with an external toothing.

At the in Fig. 2 to 4 In the embodiments shown, the high-frequency phase shifter assembly has a common housing 3 for all high-frequency phase shifters, the individual high-frequency phase shifters 1 and 2 being separated from one another by a housing plate designed as an intermediate plate of the housing.

However, the gear arrangements shown in this embodiment can also be used when each high-frequency phase shifter has its own housing. In this case, only those in the embodiments in Fig. 2 to 4 used intermediate plate 10 of the housing are divided into a cover plate for the lower phase shifter and a bottom plate for the upper phase shifter.

In Fig. 5 Now, an embodiment of a high-frequency phase shifter assembly is shown, in which the high-frequency phase shifter 1 and 2 each have their own housing 3. The housing 3 of the high-frequency phase shifter each comprise a bottom plate 18 and a cover plate 19 and side walls 32 and thus each form a sealed housing for the phase shifter 1 and 2. The phase shifter 1 and 2 are stacked in the stack, wherein the housing. 3 the high frequency phase shifter are connected together. In the exemplary embodiment, the bottom plates 18 of the housing for this purpose connection points 20, which are connected to one another via extending in the direction of the stack connecting elements 21. The individual high-frequency phase shifters 1 and 2 are arranged on each other so that the axes of rotation 4 of the pickup 5 are aligned. However, the axes of rotation 4 are not led out of the housing 3, but stored at bearings 8 above and below in or on the housing. The individual high-frequency phase shifters in the stack are thus decoupled from each other in the region of the axis of rotation 4 and the coupling points arranged there for electrical coupling of the signals into the pickups 5 through the bottom plate 18 and / or the cover plate 19, since no axle feedthrough for the axes of rotation 4 is provided , In the stack, the bottom plate 18 of the upper phase shifter 1 comes to rest on the cover plate 19 of the lower phase shifter 2. However, to electrically separate the housings, an insulating layer 22 is interposed therebetween.

The mechanical coupling of the pickup 5 of the individual phase shifters in the stack takes place in the Fig. 5 shown embodiment of a transmission which works exactly like that in Fig. 3 shown gearbox. In particular, rotatably connected to the customers 5 first gear elements 14 are provided, which cooperate with staggered second gear elements 15. In turn, gear wheels or gear segments, in particular with external teeth, are used as gear elements. The high-frequency phase shifter associated first and second transmission elements 14 and 15 are arranged and stored in the respective housing 3. Furthermore, a connecting shaft 12 is provided, on which the second gear elements 15 are arranged rotationally fixed. The connecting shaft 12, which the second transmission elements 15 connects with each other, passes through the housing 3 therethrough. For this purpose, bushings 16 for the connecting shaft 12 are provided in the bottom plate 18 and in the cover plate 19, respectively.

In the exemplary embodiment, the connecting shaft 12 is designed as a continuous shaft, which can be pushed through by shaft receiving 23 of the second gear elements 15. Alternatively, it would be conceivable to arrange connecting shaft sections, which can be plugged into one another, on the second transmission elements 15. In place of the connector, other types of connections are conceivable.

The in Fig. 5 The construction of the high frequency phase shifter assembly comprising a plurality of stackable high frequency phase shifters with a dedicated housing allows the construction of high frequency phase shifter assemblies with any number of stacked high frequency phase shifters. In particular, high-frequency phase shifter groups with three or more stacked high-frequency phase shifters can be constructed.

In Fig. 6 is now a more detailed embodiment of a stackable high-frequency phase shifter with its own housing, as in the in Fig. 5 shown embodiment of a high frequency phase shifter assembly can be used shown.

Fig. 6 shows the stackable high-frequency phase shifter thereby in an exploded view, wherein the bottom plate 18 of the housing can be seen in the lower area, while in the upper area the cover plate 19 of the housing with the angled side wall portions 32 and mounting tabs 33 for attachment with attachment points 34 of the bottom plate 18th is shown.

On the bottom plate 18, a bearing assembly 24 is shown, on which the pickup 5 is rotatably mounted about an axis of rotation 4. On the bottom plate 18 more stripline sections 7 are further arranged, which at coupling points 6 are capacitively coupled to the pickup 5. In this case, an insulating layer 30 is provided between the bottom plate 18 and the stripline sections 7. As in Fig. 6 illustrated, the pickup 5 extends like a pointer in the radial direction, while the stripline sections 7 are arranged in an arcuate manner about the axis of rotation 4. In this case, connections are to be provided for connecting radiators to the ends of the stripline sections.

The coupling of the signal in the pickup 5 via an annular coupling point 25, which is arranged in the region of the axle bearing 24 of the pickup 5 and with an in Fig. 6 not visible, annular coupling disc of the pickup 5 is capacitively coupled. The coupling in the region of the axis of rotation is independent of the angle of rotation of the pickup 5 by the respective annular coupling elements. In the region 31, a connection for the galvanic connection of the coupling point 25 can be provided.

With the consumer 5, a first transmission element 14 is rotatably connected. The gear element 14 comprises a gear segment with a partial external toothing 27 and is rotatably connected via a driving pin 29 with the pickup 5. The first gear element 14 is, like the customer, rotatably mounted about the axis of rotation 4 via a bearing arrangement (not shown in detail).

For mechanical connection with further high-frequency phase shifters in the stack, a second transmission element 15 is provided, which is also designed as a gear segment with a partial outer toothing 28. The external teeth 27 and 28 of the first and second gear element 14 and 15 mesh directly with each other. The second transmission element is also rotatably mounted in or on the housing, namely about a parallel to the axis of rotation 4 of the consumer and the first transmission element 14 extending axis of rotation. It is in Fig. 6 to see a lower bearing 26.

The bottom plate and the cover plate of the housing have in the region of the axis of rotation of the second gear element 15 openings 16 through which a connecting shaft can pass. The second transmission element 15 has an encoded shaft bushing 23, so that the second transmission elements of the high-frequency phase shifter in the stack can be rotatably connected to each other via a continuous connecting shaft and can be driven together via the connecting shaft.

In the stack several identical high-frequency phase shifter can be used. However, it is also conceivable to equip the individual phase shifters, for example, with a different number or differently arranged stripline sections 7. Likewise, it is conceivable to produce different translations for the individual high-frequency phase shifters by different pairings of first and second transmission elements 14 and 15. The mechanical coupling can still be identical. In particular, all high-frequency phase shifters have identical housings and identical connection regions for the second transmission elements 15.

In the FIGS. 7 and 8th a further embodiment of a high-frequency phase shifter assembly according to the invention is shown, in which the mechanical coupling of the high-frequency phase shifter 1 and 2 in the stack is not via a transmission, but via a lever assembly 42 of coupled levers 35. In the in the FIGS. 7 and 8th In the embodiments shown, the two high-frequency phase shifters 1 and 2 each have separate housings with base plates 18 facing one another and outer cover plates 19 on the outside. However, the high-frequency phase shifters could also be used as in, for example Fig. 1 have a common housing or stacked with identical orientation.

The levers 35 are in each case rotatably connected to the customers 5 of the high-frequency phase shifters 1 and 2 and extend in a plane perpendicular to the axes of rotation 4. In this case, the lever 35 extend on the customer 5 with respect to the axis of rotation 4 opposite side.

The lever 35 are preferably moved via a linkage 41, which is moved perpendicular to the plane of the drawing. At the linkage can be arranged a slotted guide in which a arranged on the lever guide pin is guided so that a linear movement of the rod 41 is translated into a rotational movement of the lever. Alternatively, the slide guide can also be arranged on the levers.

At the in Fig. 7 In the embodiment shown, the two levers 35 are connected to one another directly via a coupling rod 36, which also serves as a common guide pin for the two levers 35 in the exemplary embodiment. In this embodiment, the movement of the linkage generates an identical adjusting movement of the two phase shifters 1 and 2.

At the in Fig. 8 In contrast, the levers 35 'and 35 "of the first phase shifter 1 and 35" of the second phase shifter 2 are separately connected to one or more link guides of a linkage (not shown), the guide pins each having a different lever length have radial distance to the axis of rotation 4 and thereby produce the different lever lengths. The coupling of the levers 35 'and 35 "takes place in this case via the linkage A movement of the linkage produces, due to the different lever lengths, rotational movements of the takers 5 which vary in size.

At the in FIGS. 7 and 8th illustrated embodiments, the axes of rotation 4 of the pickup are each led out on one side via a bushing 9 from the respective housing and are outside the housing with the levers 35 in connection. In the embodiment, while the axis of rotation of the upper high-frequency slider 1 above, the axis of rotation of the lower high-frequency phase shifter led out of the lower housing 3 below. alternative However, the arrangement of one of the two phase shifters 1, 2 could also be rotated by 180 °, so that the axes of rotation of both high-frequency phase shifters in the stack are each led out on the same page. For this purpose, only between the cover plate of a lower high-frequency phase shifter and the bottom plate of the upper high-frequency phase shifter, a corresponding space for the lever would have to be provided.

In an alternative, not shown embodiment, the lever can be rotatably connected within the housing with the buyer 5 and led out through a slot out of the housing. In this, the axis of rotation of the pickup 5 does not have to be out of the housing at all, but may be mounted with its two ends inside the housing or on the housing. In this case, the lever may be arranged in such an embodiment on the opposite side of the pickup 5 with respect to the axis of rotation 4, and in particular extend the pickup 5 in the opposite direction. Such a configuration makes it possible to further reduce the stack height of the high-frequency phase shifter.

Alternatively to the in Fig. 7 and 8th illustrated embodiments with separate housings for the high-frequency phase shifter, the high-frequency phase shifter assembly could also have a common housing for the high-frequency phase shifter with a corresponding intermediate plate.

In FIGS. 9a and 9b Now two variants are shown as a rotation axis 4 of a pickup 5 can be stored in or on the housing. Shown is the storage of at least one, not led out of the housing end 37 of the axis of rotation 4, wherein the storage takes place in particular in the region of the housing plate 10 and 18 respectively. In the in Fig. 9a shown variant is the end 37 of the rotation axis 4 in a bearing sleeve 38, which is arranged on the housing plate 10, 18, stored. In the in Fig. 9b In contrast, the end 37 of the axis of rotation 4, on the other hand, has a bearing cup 39 in which a bearing pin 40 which engages with the housing plate 10, 18 engages. The storage must be natural not directly on the housing plate 10, 18 done, but can also be done via a separate, arranged in the housing bearing assembly.

Regardless of the specific storage, the inventive separation of the axes of rotation of the customer allows the individual high-frequency phase shifter in the stack and the interposition of the coupling points for the signals in the customers shielding each other housing plate improved electrical decoupling of the individual high-frequency phase shifter. According to the invention, the electrical coupling of the signals in the region of the axis of rotation and the mechanical coupling of the pickup is spatially separated and thus enables improved electrical decoupling in the individual consumers in the stack.

The high-frequency phase shifter assembly is used in particular for controlling antenna arrays, in particular in order to lower the radiation pattern can. Alternatively or additionally, an azimuth adjustment of the radiation pattern is thus possible. The adjustment can be done manually and / or via a drive motor.
