Definitions
- the invention relates to a waveguide twist for connecting electromagnetic waveguides, consisting of a torsion element with at least three gaps lying side by side without gaps around the axis of the same rotatable individual parts, in which each of the individual parts is a central Through hole with a corresponding cross section of the waveguide Has cross-section and in which the through holes of the individual parts are not aligned rotated state of the torsion element with each other (DE-C-3 733 397).
- Such a waveguide twist can be used to connect rectangular or elliptical Waveguides are used.
- the following is the rectangular cross-section taken into account, representative of the elliptical Cross-section.
- Such a waveguide twist is required, for example, if a Waveguide with another waveguide or with a device with one Waveguide connection should be connected and if the axes of the respective Connection points are in mutually rotated planes.
- a possible one Areas of application are, for example, antennas with a parabolic reflector and one given by a rectangular waveguide feed line.
- To the A further waveguide is connected to the feeder line Establishes a connection to a transmitting and receiving system.
- the Polarization plane in which the electromagnetic waves to be transmitted swing is fixed by the rectangular waveguide of the feed line. It will be for the antenna by appropriate rotation or arrangement of the feed line in Reflector set.
- the connection end of the feed line is also set, so that their rectangular opening can assume different positions. The can cause difficulties if the position of the continuing Waveguide and in particular the position of an intermediate device are fixed, whereby the position of the connection openings of these components is also fixed. It must then be made for the respective application Transitional components are used, which guide the loss with as little loss as possible Waves between the feed line and the component to be connected to it enable.
- the waveguide twist according to the aforementioned DE-C-3 733 397 exists For example, from three waveguide sections that are mutually opposite about their longitudinal axis are rotatably connected. As a result, the waveguide twist is open different angles between the axes of the clear cross sections at its adjustable at both ends.
- At the middle waveguide section there is an in Lever extending lever longitudinally rotatably attached.
- To the Both ends of the lever protrude from pins which engage in guide grooves, which outside on the other two waveguide sections, in the longitudinal direction of the Waveguide twists running, are attached.
- the structure of this well-known Waveguide twists is complex. It increases with the number of Waveguide sections more complicated. The angles at which the waveguide sections deviate are rotatable against each other, is limited in that the pin of the lever still engage in the guide grooves of the waveguide sections.
- the invention has for its object the waveguide twist described above easier to design without limiting the angle of rotation.
- This waveguide twist is simple in construction and easy to operate without having to externally visible parts are used. Its angle of rotation is only determined by the Extension of the recesses made in the individual parts in the circumferential direction limited. It consists of a suitable number of individual parts, of which the one with a rotation the neighboring through the into the corresponding recess engaging pin.
- Individual parts are automatically taken along and rotated through the correct angle. The angles around which the individual parts are to be rotated remain the same The more individual parts are used, the smaller the angle of rotation of the waveguide twist.
- the electrical losses caused by the torsion element are included increasing number of individual parts less. The reflection factor of the same will then cheaper.
- the torsion element is not only one when it is first assembled Waveguide arrangement is advantageous, but also when, for example, on a already installed antenna arrangement set a different polarization level shall be.
- Fig. 1 is a Tosionselement for a waveguide twist according to the invention in section.
- Fig. 4 shows the torsion element of FIG. 1 in an exploded view.
- Fig. 5 in a schematic representation of an antenna arrangement with a Torsion element.
- a torsion element for a waveguide twist according to the invention has at least three individual parts lying next to each other without gaps, around the axis of the Torsion element are rotatable.
- the two end parts can also be from the two waveguides to be connected to one another. In this extreme case then only one additional individual part is arranged between the two waveguides.
- the Individual parts all have a rectangular (elliptical), central through hole, whose clear width and dimensions are the same.
- the individual parts of the In a preferred embodiment, torsion elements are circular disks. she can then be held together particularly easily in a cylindrical housing and are guided, the inside diameter of the outside diameter of the Discs corresponds. But it is also every other meaningful structure of the Torsion element conceivable with which all individual parts are held together as a unit can and that ensures the relative rotatability of the individual parts.
- a torsion element 1 for a waveguide twist made of five individual parts. That’s four circular disks 2, which in a cylindrical, pot-shaped housing 3 as a fifth item by one common axis are rotatably mounted.
- the inside diameter of the housing 3 corresponds to the outer diameter of the discs 2.
- the housing 3 can in Mounting position can be rotatably attached to a holding plate 4 in the circumferential direction. It engages in slots 5 and 6 of the holding plate 4 (Fig. 4).
- a feed line 7 for an antenna attached, for example, a waveguide with a rectangular Cross section. All discs 2 and the bottom 8 of the housing 3 have one central, rectangular through hole 9.
- the Torsion element 1 align the through holes 9 of all individual parts 2 and 8 the same with each other and with the feed line 7, as shown in Fig. 1.
- Each of the disks 2 has a recess on one end face, which is preferred Embodiment designed as an elongated hole 10 extending in the circumferential direction is.
- the depression could also be circular or with a different cross section his. Only the length of their extent in the circumferential direction is important. Representative for all possible embodiments, the elongated hole 10 considered.
- On the other end of the discs 2 is in the axial Towards a pin 11. In the assembly position, a pin 11 engages one Disc 2 in an elongated hole 10 of the adjacent disc 2.
- the length of the Elongated holes 10 limit the angle by which a disc 2 relative to one adjacent disc 2 is rotatable.
- the bottom 8 of the housing 3 a pin 11, which in the slot 10 of the engages the same adjacent disc 2.
- the holding plate 4 is also with a Elongated hole 10 equipped for receiving the pin 11 of the adjacent disc 2.
- the Bottom 8 of the housing 3 and four disks 2 - have the elongated holes 10 for example, a length corresponding to an angle of 18 °.
- the Through hole 9 in the bottom of the housing 3 is then opposite the feed line 7 rotatable by a rotation angle of 90 °. If a different angle of rotation can be achieved if the length of the elongated holes 10 must be the same either the number of Slices 2 or, if the number of slices 2 remains the same, the length of the Elongated holes 10 are changed.
- the elongated holes 10 can each have the same length in all disks 2 Have circumferential direction, as explained with the angle of 18 °. You can but also be of different lengths, so that the individual disks 2 are different be rotated far. In the described embodiment with five disks 2 and a rotation angle of 90 ° could that of the respective length in the circumferential direction corresponding angle of the adjacent discs 2 also as follows graded: 12 ° -20 ° -24 ° -20 ° -12 °. Such a structure of a torsion element 1 can result in an even more favorable reflection factor.
- Fig. 5 the tip of a mast 12 is schematically indicated, on which a parabolic reflector 13 of an antenna is mounted.
- the rectangular waveguide designed feed line 7 attached to the free end an exciter 14 serving to illuminate the antenna is attached.
- a device 15 on the mast 12 mounted to which a waveguide 16 is connected, which is not connected to a shown transmitting and receiving device is connected.
- a torsion element 1 is attached between the device 15 and the feed line 7, a torsion element 1 is attached.
- the plane of polarization of the antenna can be rotated due to the torsion element 1 the feed line 7 can be changed without the device 15 or the waveguide 16 their position must be changed.
