Description
Anordnung zur Veränderung des Polarisations- und/oder Strahlungsdiagrammes einer Antenne. Arrangement for changing the polarization and / or radiation diagram an antenna.
In der Hochfrequenztechnik werden z. Zt. vorwiegend Antennen mit linearer Polarisation verwendet. Stationäre Funkdienste benutzen meist horizontal polarisierte Antennen, während bei beweglichen Funkdiensten die vertikale Polarisation überwiegt.In high frequency technology, for. Currently mainly antennas with linear Polarization used. Stationary radio services mostly use horizontally polarized Antennas, while vertical polarization predominates in mobile radio services.
Zirkular polarisierte Antennen werden nur in wenigen Fällen, z. B. bei Funkverbindungen mit Raumflugkörpern, verwendet.Circular polarized antennas are only used in a few cases, e.g. B. used in radio communications with spacecraft.
Die derzeit hergestellten Antennen sind in der Regel entweder für zirkulare oder für lineare Polarisierung vorgesehen, wobei durch ein bekanntes elektrisches Verfahren der Drehsinn zirkular polarisierter Antennen und durch eine veränderte mechanische Anordnung die Polarisationsebene linear polarisierter Antennen geändert wird.The antennas currently manufactured are usually for either circular or intended for linear polarization, being by a known electrical Procedure of the direction of rotation of circularly polarized antennas and changed by one mechanical arrangement changed the plane of polarization of linearly polarized antennas will.
Bisher sind einige Anwendungsfälle bekannt geworden, bei denen es möglich ist, durch entsprechende Umschaltvorrichtungen die gebräuchlichsten Polarisationsarten (zirkular rechtsdrehend, zirkular linksdrehend, linear horizontal, linear vertikal) zu wählen. Jedoch haben diese Vorrichtungen den Nachteil, daß sich bei Umschaltung der Polarisation die Impedanz des Anschlußpunktes ändert und die Korrektur dieser Änderung nur 1it erheblichem Aufwand möglich ist.So far, some use cases have become known in which is possible, the most common types of polarization by means of appropriate switching devices (circular clockwise, circular counterclockwise, linear horizontal, linear vertical). However, these devices have the disadvantage that when the polarization is switched, the impedance of the connection point changes and the Correction of this change is only possible with considerable effort.
Die Erfindung hat zur Aufgabe, eine Antennenanordnung zu schaffen, die mit einem Minimum an Aufwand eine Einstellung auf beliebige Polarisation ermöglicht, wobei siL die Impedanz des Anschlußpunktes nicht ändert.The invention has for its object to provide an antenna arrangement, which enables an adjustment to any polarization with a minimum of effort, where siL does not change the impedance of the connection point.
Die Aufgabe wird gemäß der Erfindung durch eine Anordnung von zwei linear polarisierten Antennensystemen gelöst, deren Polarisationsebenen senkrecht zueinander stehen und die mittels einer Leitung miteinander verbunden sind, wobei durch entsprechende Wahl des Anschlußpunktes auf der Leitung ein beliebiges Diagramm der Anordnung eingestellt werden kann, ohne daß sich dabei die Impedanz des Anschlußpunktes ändert. Die beiden Antennensysteme können Ubereinander, nebeneinander oder auf einer gemeinsamen Achse angebracht werden.The object is achieved according to the invention by an arrangement of two linearly polarized antenna systems, whose planes of polarization are perpendicular stand to one another and which are connected to one another by means of a line, wherein any diagram can be created by selecting the appropriate connection point on the line the arrangement can be adjusted without affecting the impedance of the connection point changes. The two antenna systems can be on top of each other, next to each other or on one common axis are attached.
Ein Ausführungsbeispiel der Anordnung gemäß der Erfindung wird anhand der beigefügten Figur erläutert.An embodiment of the arrangement according to the invention is based on the accompanying figure explained.
Bei Anschluß der Anordnung im elektrischen Mittelpunkt der Leitung 3 oder einem anderen davon entfernten Punkt 4 entsteht eine lineare Polarisation, deren Ebene mit einer Winkelhalbierenden der Anordnung identisch ist. Bei Anschluß in einem Punkt 5, der elektrisch von Punkt 4 entfernt ist, tritt eine ebenfalls lineare Polarisation in der Ebene der anderen Winkelhalbierenden auf. Bei Anschluß in einem Punkt 6, der elektrisch von Punkt 4 entfernt ist, entsteht eine zirkulare Polarisation definierter Drehrichtung.When connecting the arrangement in the electrical center of the line 3 or another thereof distant point 4 results in a linear polarization, the plane of which is identical to an angle bisector of the arrangement. When connected in a point 5, the electrical is away from point 4, a likewise linear polarization occurs in the plane of the other bisector. When connected in a point 6, the electrical is removed from point 4, a circular polarization with a defined direction of rotation is created.
Somit ergibt sich die Möglichkeit, bei Anschluß zwischen Punkt 5 und Punkt 7, der ebenfalls elektrisch von Punkt .4 entfernt ist, neben den oben genannten Grundformen der Polarisation auch jede beliebige Mischform (elliptische Polarisation) zu erzeugen.Thus there is the possibility of connecting between point 5 and point 7, which is also electrical is removed from point .4, in addition to the above-mentioned basic forms of polarization, any mixed form (elliptical polarization) can also be generated.
Wird eine kontinuierliche Veränderung des Polarisations-und/oder Strahlungsdiagramms gewünscht, so kann z.3. unter Beachtung bekannter hochfrequenztechnischer Gesichtspunkte eine Vorrichtung von Schleifkontakten oder eine entsprechende nichtgalvanische txopplungsvorrichtung zwischen den Punkten 5 und 7 eingefügt werden.Will be a continuous change in the polarization and / or radiation diagram desired, z.3. taking into account known high-frequency technical aspects a device of sliding contacts or a corresponding non-galvanic coupling device inserted between points 5 and 7.
Soll nur ein einziges oder eine begrenzte Anzahl von Diagrammen eingestellt werden, genügt ein fester oder in Stufen veränderlicher Anschluß.Should only set a single chart or a limited number of charts a fixed or variable connection is sufficient.
