Description
Die Erfindung bezieht sich auf eine außenstruktur-konforme Antenne und insbesondere eine flache Breitbandantenne in einer Trägerstruktur eines Fahrzeugs und insbesondere eines Fluggeräts, wobei die Trägerstruktur insbesondere eine Trägersystem-Primärstruktur ist.The invention relates to an outer structure-compliant antenna and in particular a flat broadband antenna in a support structure of a Vehicle and in particular an aircraft, wherein the support structure especially a carrier system primary structure.
Der Begriff "Fluggeräte" betrifft alle nur denkbaren Geräte, die mit beliebigen Antrieben durch die Luft bewegt werden können, wie Flugzeuge, Hubschrauber, Luftschiffe, Drohnen, Raketen und dergleichen. Die Raketen sind ein Beispiel dafür, dass die Erfindung auch Fluggeräte bzw. Flugkörper betreffen kann, die geeignet sind, sowohl in der Luft als auch im luftleeren Raum zu fliegen.The term "aircraft" refers to all imaginable devices, with any Drives can be moved through the air, such as airplanes, helicopters, Airships, drones, rockets and the like. The rockets are an example that the invention can also affect aircraft or missiles that are suitable to fly both in the air and in a vacuum.
Die zunehmende Anzahl von Avionikfunktionen bei Fluggeräten, im besonderen bei Flugzeugen lässt auch die erforderliche Anzahl von Antennen entsprechend ansteigen; bis zu sechzig Antennensysteme und mehr sind bereits heute keine Seltenheit mehr. Diese Problematik erfordert neue Wege für den Einbau bzw. die Unterbringung von Antennen beispielsweise bei Flugzeugen. Eine mögliche Lösung dieses Problems ist die Integration der Antennen in die Trägerstrukturen von Fahrzeugen und/oder Fluggeräten.The increasing number of avionics functions in aircraft, in particular for aircraft also leaves the required number of antennas accordingly increase; Up to sixty antenna systems and more are already none today Rarity more. This problem requires new ways for the installation or the Housing of antennas, for example on aircraft. A possible The solution to this problem is the integration of the antennas in the carrier structures of vehicles and / or aircraft.
Bei der Lösung der aufgezeigten Problematik ist auch zu bedenken, dass der Einsatz künftiger luftgestützter Datenübertragungssysteme wegen immenser Datenmengen eine große HF-Bandbreite erfordert. Aus diesem Grund kommen immer höhere Frequenzen zur Anwendung. Der Markt bietet derzeit überwiegend Systeme im X- oder Ku-Band an.In the solution of the indicated problem is also to be considered that the Use of future airborne data transmission systems because of immense Data volumes require a large RF bandwidth. For this reason come ever higher frequencies for use. The market currently offers mostly Systems in the X or Ku band.
Neben der Forderung nach einer großen Bandbreite wird naturgemäß eine große Reichweite für die Datenübertragung gefordert. Dies kann nur durch Antennen mit entsprechend großer Apertur oder mit Arrays erreicht werden, die aus mehreren Einzelstrahlern bestehen. Luftgestützte schwenkbare Reflektorantennen sind derzeit als kommerzielle Produkte erhältlich. Deren Unterbringung ist jedoch meistens ein Problem. Es wurde daher auch schon überlegt, anstatt einer relativ großen Reflektorantenne Teile der beispielsweise Flugzeugoberfläche als strahlende Apertur zu nutzen.In addition to the demand for a large bandwidth is naturally a large Range required for data transmission. This can only be done with antennas correspondingly large aperture or can be achieved with arrays consisting of several Single radiators exist. Air-supported pivotable reflector antennas are currently available as commercial products. Their accommodation is however mostly a problem. It was therefore already considered, rather than a relative large reflector antenna parts of the example airplane surface as use bright aperture.
Bislang hatte zum Beispiel eine Flugzeugstruktur ausschließlich die Funktion, lasttragende und aerodynamische Aufgaben zu übernehmen. Die strukturelle Oberfläche musste dementsprechend verschiedene mechanische Belastungen aushalten.So far, for example, an aircraft structure has only the function of to undertake load-bearing and aerodynamic tasks. The structural Surface had accordingly different mechanical loads withstand.
Mit der Funktionserweiterung der Strukturoberfläche von Fluggeräten auch als Antenne wirksam zu werden ergeben sich zusätzliche Probleme hinsichtlich der Stabilität der Strukturen. Elektronisch bedingt müssen für die Antennen geeignete Materialien eingesetzt werden; dabei darf aber die lasttragende Funktion der Struktur nicht negativ beeinflusst werden.With the functional extension of the structure surface of aircraft also as Antenna to be effective, there are additional problems in terms of Stability of the structures. Electronically conditioned must be suitable for the antennas Materials are used; but the load - bearing function of the Structure should not be negatively affected.
Aus den eingangs genannten Gründen geht die Fachwelt mehr und mehr davon ab, Antennen zu bauen bzw. anzuwenden, die sich in Form von Stäben, Spiralen, Hornteilen oder anderen Gebilden von der Struktur bzw. der Außenhaut von Fahrzeugen und/oder Fluggeräten abheben. Dadurch können Strömungswiderstände verringert und die Gefahr von rein mechanischen Beschädigungen der Antennen zumindest das reduziert werden.For the reasons mentioned above, the professional world is more and more of it to build or use antennas in the form of rods, spirals, Horn parts or other structures of the structure or the outer skin of Take off vehicles and / or aircraft. Thereby can Reduced flow resistance and the risk of purely mechanical Damage to the antennas at least that can be reduced.
Die zitierte Problematik hat dazu geführt, außenstruktur-konforme Antennen zu entwickeln und diese weitmöglich bzw. optimal, das heißt identisch der vorgegebenen Form von Strukturen bei Fahrzeugen und/oder Fluggeräten anzupassen.The cited problem has led to outer structure-compliant antennas too develop and this as far as possible or optimal, that is identical to the predetermined form of structures in vehicles and / or aircraft adapt.
Zum diesbezüglich bekannten Stand der Technik sei verwiesen auf eine Publikation von Dipl.-Ing. Robert Sekora u.a. unter dem Titel: "Conformal Airborne Array Antenna for Broad Band Data Link Applications in the X-Band". Diese Abhandlung zeigt im wesentlichen die Unterschiede auf zwischen herkömmlichen und aktuelleren außenstruktur-konformen Antennensystemen, die eng an die Struktur - in diesem Falle von Flugzeugen - angepasst sind.Reference is made to a known prior art in this regard Publication of Dipl.-Ing. Robert Sekora et al. under the title: "Conformal Airborne Array Antenna for Broadband Data Link Applications in the X-Band " Essay essentially shows the differences between conventional ones and more recent outer structure compliant antenna systems that closely conform to the Structure - in this case of aircraft - are adjusted.

Der Autor erklärt in dieser Publikation die strukturelle Integrierbarkeit einer Array-Antenne. Des weiteren wird der strukturelle Aufbau hinsichtlich seiner elektromagnetischen Funktion bestätigt.Another relevant pre-publication is an essay, also by Dipl.-Ing. Robert Sekora, under the title: "Structured aircraft antenna for Wideband applications in the X-band ". The author explains in this publication the structural integrability of an array antenna. Furthermore, the structural Structure confirmed regarding its electromagnetic function.
Der Erfindung liegt die Aufgabe zugrunde, außenstruktur-konforme Antennen derart in die Trägerstrukturen und insbesondere in Trägersystem-Primärstrukturen von Fahrzeugen und/oder Fluggeräten zu integrieren, dass jegliche aerodynamischen Nachteile vermieden werden und die Strukturfestigkeit in den Integrationsbereichen weitestgehend erhalten bleibt, bei gleichzeitiger Gewährleistung der Antennen-Funktionalität.The invention is based on the object, outer structure-compliant antennas such in the carrier structures and in particular in carrier system primary structures of vehicles and / or aircraft integrate that any aerodynamic disadvantages are avoided and the structural strength in the Integration areas is largely retained, while at the same time Ensuring the antenna functionality.

Die erfindungsgemäße Integration der Antenne in die Flugzeugstruktur vermeidet jegliche aerodynamischen Nachteile, die durch eine Antenne entstehen könnten bei weitestgehender Erhaltung der Strukturfestigkeit.Figure 1a illustrates very clearly the advantages of an antenna according to the Invention compared to a conventional antenna according to Figure 1 b.

Figur 2 zeigt ein Beispiel für den Aufbau einer Antenne, beispielsweise in planarer
Bauform nach der Erfindung in ihren wesentlichen Einzelteilen. Die Basis für die
Befestigung der Antenne bildet hier eine Trägersystem-Primärstruktur 1 eines
Fluggeräts, die in vielen Anwendungsfällen aus CFK besteht. Der eigentliche
elektromagnetische (im folgenden kurz mit EM bezeichnet) Funktionskern 2 der
Antenne wird über eine geeignete Kleberschicht 3 mit der Trägersystem-Primärstruktur
1 verbunden. Den wesentlichen oberen respektive äußeren
strukturangepassten Abschluss der Antenne bildet eine Abdeckplatte in Form
eines sogenannten Frontdielektrikums 4, welches ebenfalls über eine
Kleberschicht 3 mit dem elektromagnetischen Funktionskern 2 verbunden wird.
Die oberen Flächenstrahler der Antenne, die auf dem Frontdielektrikum 4 befestigt
sind, tragen das Bezugszeichen 5.Figure 2 shows an example of the structure of an antenna, for example in planar
Design according to the invention in its essential parts. The basis for the
Attachment of the antenna forms a carrier system

Bei den deckungsgleichen Bohrungsreihen 6 und 7 handelt es sich um
Durchbrüche für die elektrische Verkabelung der erfindungsgemäßen
außenstruktur-konformen Antenne.The congruent rows of
Die Gesamtdicke der erfindungsgemäßen Antenne beträgt vorzugsweise einige Millimeter, so dass deren Integration in eine Flugzeugstruktur keine oder allenfalls nur eine vernachlässigbar geringe Strukturbeeinflussung bedeutet.The total thickness of the antenna according to the invention is preferably a few Millimeters, so that their integration into an aircraft structure no or at best only a negligible structural influence means.
Die Abbildung 3 zeigt eine Möglichkeit der optimalen Einbringung bzw. Integration
einer Antenne in die Trägersystemprimärstruktur 1, beispielsweise bei einem
Flugzeug. Hierzu besitzt die Trägersystem-Primärstruktur 1 eine Mulde 8 oder
eine bereichsweise Vertiefung, die durch spitzwinkliges Einbiegen der Bereiche 9
und 10 der Trägersystem-Primärstruktur 1 herbeigeführt wird. Alternativ dazu sind
gegebenenfalls auch stumpfwinklige bzw. stufenweise Übergänge realisierbar; so
könnte bei einem Winkel β = 90° der Bereich 9 der Trägersystem-Primärstruktur 1
im Extremfall vertikal nach unten abgebogen sein, so dass der EM-Funktionskern
2 in seinen Kantenbereichen ebenfalls rechteckig ausgebildet sein könnte.Figure 3 shows a possibility of optimal incorporation or integration
an antenna in the carrier system
Demgegenüber sollte im Rahmen der Erfindung der Winkel α spitzwinklig bleiben,
da von seiner Bemessung die Größe der Klebefläche im Bereich 10 der
Trägersystem-Primärstruktur 1 für den entsprechend abgeschrägten Teil 11 des
Frontdielektrikums 4 abhängt; je kleiner, das heißt je spitzwinkliger der Winkel α
ist, umso größer wird die Klebefläche im Bereich 10 der Trägersystem-Primärstruktur
1.In contrast, in the context of the invention, the angle α should remain acute-angled,
because of its size, the size of the adhesive area in the range of 10
Carrier system
Der Bereich 9 liefert in radialer Sicht Raum für die Unterbringung des EM-Funktionskerns
2, während das Einbiegen der Trägersystem-Primärstruktur 1 im
Bereich 10 das lasttragende, außenkontur-erhaltende Einkleben einer
