Claims (15)

österreichisches Patentamt AT509 538B1 2013-02-15 [0073] Mit der vorliegenden Erfindung lassen sich ultraleichte, hochleitfähige HF-Antennen realisieren und die Anwendungsmöglichkeiten sind natürlich nicht auf die hier vorgestellten Beispiele eingeschränkt. Die größten Vorteile durch die Verwendung von Carbon liegen im geringen Bauteilgewicht bei gleichzeitiger Dimensionsstabilität auf Grund des gegen Null tendierenden CTE (Coefficient of Thermal Expansion) des Carbons. D.h., auch bei großen Temperaturschwankungen kommt es praktisch zu keinen Veränderungen der Abmessungen der Bauteile. [0074] Die Bauteile erreichen höchste Werte in Bezug auf Festigkeit und Steifigkeit und die entsprechenden Antennen eignen sich daher in allen Bereichen des Leichtbaus, wie Luft- und Raumfahrt, aber auch für Bereiche der kommerziellen Rundfunk- und Fernsehübertragung. Patentansprüche 1. Antenne (1) mit zumindest einem elektrisch leitenden Sende/Empfangskörper (2) und/oder zumindest einem elektrisch leitenden Hohleiter (20), dadurch gekennzeichnet, dass der zumindest eine Sende/Empfangskörper (2) und/oder der zumindest eine Hohlleiter (20) zumindest bereichsweise aus elektrisch hoch-leitfähigem Carbon (3, 30) gebildet ist/sind.Austrian Patent Office AT509 538B1 2013-02-15 With the present invention, ultralight, highly conductive RF antennas can be realized and the applications are of course not limited to the examples presented here. The biggest advantages of using carbon are the low component weight and the dimensional stability due to the near-zero CTE (coefficient of thermal expansion) of the carbon. That is, even with large temperature fluctuations, there is virtually no change in the dimensions of the components. The components achieve the highest values in terms of strength and rigidity and the corresponding antennas are therefore suitable in all areas of lightweight construction, such as aerospace, but also for areas of commercial radio and television broadcasting. 1.
