Description
Freitragende L inearantenne Für Sende- und Empfangsgeräte der drahtlosen Nachrichtenübermittlung, insbesondere für die mit kurzen Wellen arbeitenden Geräte, werden vielfach freitragende lineare Antennen verwendet. Solche Antennen müssen für verschiedene Zweck; biegsam sein, z. 13. uln sie in relativ kleinem Raum unterbringen zu können. Sie müssen ferner elastisch sein, damit sie durch die Verbiegung nicht ihre Form verlieren. Ferner sollen sie eine genügende mechanisch Dämpfung besitzen, damit sie hei Windeinwirkung oder infolge mechanischer Erschütterungen keine lange Schwingungsdauer haben. Die bekannten, ans massiven Stangen oder ans Rohren bestehenden, meist sich von der Basis zur Spitze hin verjüngenden Antennen erfüllen diese Erfordernisse nicht, da sie einerseits nur wenig mechanisch gedämpft sind und da ferner das Material solcher Antennen beim Biegen einer starken Beanspruchung ausgesetzt würde.Cantilever aerial for wireless transmitters and receivers Communication, especially for devices that work with short waves, Cantilevered linear antennas are often used. Such antennas must for various purposes; be flexible, e.g. 13. uln place them in a relatively small space to be able to. They must also be elastic so that they do not bend lose their shape. Furthermore, they should have sufficient mechanical damping, so that they do not last long when exposed to wind or as a result of mechanical vibrations Have oscillation period. The well-known, consisting of solid rods or pipes, mostly antennas tapering from the base to the tip meet these requirements not because, on the one hand, they are only slightly mechanically damped and, furthermore, because of the material such antennas would be subjected to severe stress when bending.
Eründungsgeinäli bestellt die neue Antenne aus einem sich zur Spitze verjüngenden Bündel von verschieden langen, in einem geineinsanien Fuß gehalterten Drähten, wobei jedes Drahtende die längeren, es überragenden Drähte umschlingt, so daß mechanische Schwingungen der Bündelantenne gedämpft werden. Eründungsgeinäli ordered the new antenna from a tapered bundle of different lengths of wires held in a single foot, each end of the wire looping around the longer wires protruding from it, so that mechanical vibrations of the bundle antenna were dampened .
In der Abbildung ist eine Antenne geittül@l der Erfindung dargestellt. Sie setzt sich, wie nian sieht, ans einer Anzahl von Einzeldrähten zusammen, die um den längsten Dralit lteruin (es können auch mehrere Drähte von der Gesamtlänge der Antenne verwendet werden) angeordnet sind. Jedes der oberen Enden der umgebenden I#--inzeldriihte ist zu einer Üse "ebogen, durch die die jeweils längeren Drähte hindurchgeführt sind und zusammengehalten werden. Alt der Basis sind sämtliche Drähte# miteinander verbunden. Diese Konstruktion hat den Vorteil, daß infolge der Unterteilung und der Möglichkeit, daß @ sich die I?ützeldrähte gegeneinander verschieben können, bei Biegung der Antenne eine geringere 1jeanspruchung des Materials stattfindet. als wenn die Antenne gleicher Foren ans Vollinetall bestehen würde. Die Reibung der einzelnen Drähte gegeneinander erhöht wesentlich die mechanische Dämpfurig der Antenne, so daß die Zeitkonstante für die inechanicch@ii Schwingungen klein wird. Man könnte verinuten, daß durch die gegenseitige Berührung der Einzeldrähte Krachgeräusche hei Aneines Empfangsgerätes auftreten. Dies ist indessen nicht der Fall, da ja die beirac1tharten Teile der Einzeldrähte sich iininer auf gleiclteln Potential befinden. Zu erwähnen wäre noch der weitere Vorteil, der in der einfachen und billigen Herstellung besteht.In the figure, an antenna geittül @ l of the invention is shown. As nian sees, it is made up of a number of individual wires that around the longest Dralit lteruin (there can also be several wires of the total length of the antenna) are arranged. Each of the upper ends of the surrounding I # - inzeldriihte is to a loop through which the longer wires are passed through and held together. Old of the base are all wires # connected with each other. This construction has the advantage that as a result of the subdivision and the possibility that @ the I? tzel wires can move against each other, when the antenna is bent, there is less stress on the material. as if the antenna of the same forums would exist on solid metal. The friction of the individual wires against each other significantly increases the mechanical damping Antenna, so that the time constant for the inechanicch @ ii oscillations becomes small. One could imagine that the mutual contact of the individual wires made cracking noises hot on a receiving device. However, this is not the case, since the in the case of hard parts of the individual wires, they are all at the same potential. Another advantage that should be mentioned is that it is simple and cheap to manufacture consists.
