Description
Züt"ErzieIniig# einer- möglichst großen Reichweite mit einem längs geschlitzten Hohlrohrstrahler gibt es einen günstig-en Wert für die Strahlungsdämpfung des Rohres, der bisher durch Wahl der richtigen Öffnungsbreite des strahlenden Schlitzes experimentell ermittelt wurde. Dieses Verfahren isi 'dl##r verAl#nismäßig umständlich, da sich die '-Schlitihreite nicht ohne weiteres verändern läßt und deshalb eine größere Anzahl von Rohren mit verschiedener Schlitzbreite vorrätig gehalten werden muß. Bei sehr langen, Strahlerii kann überdies die erforderliche Schlitzbreite- so gering werd-en, daß bei großen Senderleistungen ein Sprühen der Schlitzkanten eintritt.Züt "ErzieIniig # a- as large a range as possible with a lengthways slotted hollow tube radiators, there is a favorable value for radiation attenuation of the tube, which was previously made by choosing the correct opening width of the radiating slot was determined experimentally. This procedure is verAl ## r cumbersome, since the 'slot cannot be changed easily and therefore a larger number of pipes with different slot widths are kept in stock got to. In the case of very long radiators, the required slot width can also be become so low that, with high transmitter powers, the edges of the slot are sprayed entry.
Zur Behebung dies-er Mängel' wird erfin'dungsgemäß vorgeschlagen, die Schlitzbreite in erster Linie nach dem Gesichtspunkt genügender, Spannungsfestigkeit zu dimensionieren und die.günstigst-, Strahlungsdämpfung deis Rohres dadurch einzustellen, daß die Schlitzbreite von vornherein etwas breiter als erforderlicli gewählt und diePol'arisationsrichtung der Rohrwelle um einen bestimmten Winkel gegen die Winkellage des-Schlitzes versetzt wird.To remedy this deficiency, it is proposed according to the invention, the slot width primarily from the point of view of sufficient dielectric strength to dimension and to adjust the most favorable radiation attenuation of the pipe, that the slot width is chosen from the outset to be somewhat wider than necessary and the polarization direction of the tubular shaft by a certain angle against the angular position des slot is offset.
Dies kann beispielsweise durch die in Abb. i dargestellte- Vorrichtung geschehen. Das Hohlrohr besteht hier aus zwei Teilen, einem feststehenden i und einem verdrehbaren 2, Der feststehende enthält den Schlitz 3, der angenommenermaßen parallele Kanten besitzt, aber auch andersartig, beispielsweise keilförmig ausgebildet sein kann. In den drehbaren Rohrteil mündet der DiP01 4 ein, der durch das koaxiale Kabel 5 gespeist wird# Das Rohr wird demgemäß zu"11-Wellen angeregt. Wenn der Dipol senkrecht auf der durch die Mittellinie des Schlitzes und die Rohrachse gelegten Ebene steht, fällt die Zone maximaler Wandströme. - mit der Lage des Schlitzes zusammen, so daß zwischen den Rändern des. Schlitzes die größtmöglichen Spannungsdifferenzen herrschen.. Die Schlitzbreite wird nun von -vornher4#in# -so ge*ählt, 'daß dieser Lage eintretende Strahlungsdämpfung größer als die optimale ist. Dreht man dann den Dipolteil um go', so findet überhaupt keine Ab- strahlung- siatt, da der Schlitz unerregt bleibt. Die optimale Strahlungsdämpfung wird mithin in irgendeiner Zwischenstellung erzielt und; läßt sich mit der beschriebenen Vorrichtung leicht einstellen.This can be done for example by the device shown in Fig. I. The hollow tube here consists of two parts, a fixed i and a rotatable 2, the fixed contains the slot 3, which is assumed to have parallel edges, but can also be designed differently, for example wedge-shaped. The DiP01 4 feeds into the rotatable tube part and is fed by the coaxial cable 5 # The tube is accordingly excited to 11 waves Zone of maximum wall currents - together with the position of the slot, so that the greatest possible voltage differences prevail between the edges of the slot .. The slot width is now from -forward4 # to # - so that the radiation attenuation occurring in this position is greater than the optimum is Turning then to Dipolteil to go ', thus finds no waste strahlung- siatt because the slot remains unexcited the optimal radiation damping is therefore achieved in any intermediate position, and;.. can be easily with the device described set.
Die, in Abb. i angenommene konstante Schlitzbreite ist unwesentlich. Der Schlitz kann auch keilförmig ausgebildet sein. Auch kann er aus mehreren, durch metallische Brücken voneinander getrennten Abschnitten bestehen, wie es in Abb.:2 dargestellt is«t. Statt des Dipols kann selbstverstän.dlich auch eine andere Erregungsvorrichtung, beispielsweise -eine KQpplungsschleife, vorgesehen sein. 1.The constant slot width assumed in Fig. I is insignificant. The slot can also be wedge-shaped. He can also choose from several, through metallic bridges are made up of separate sections, as shown in Fig .: 2 is shown. Instead of the dipole, another excitation device can of course also be used, for example a coupling loop may be provided. 1.
