    Mehrfachantennenanordnung   zum   Senden von kurzen Wellen.   



   Es ist bekannt, dass man durch Verwendung von mehreren Antennen, die in einem bestimmten Abstande voneinander angeordnet sind und gegebenenfalls mit entsprechenden   Phasenverschiebungen   schwingen, ein Sendesystem mit ausgesprochener Richtwirkung bekommt. Durch die Kombination von mehreren Hochantennen, die längs einer Geraden aufgestellt sind, erhält man ein Antennensystem mit zweiseitiger   Richtwirkung.   Um eine einseitige Richtwirkung herzustellen, werden bekanntlich Kombinationen von gerichteten und ungeriehteten Antennen verwendet. Arbeitet man dagegen mit kurzen Wellen, so lässt sich nach der vorliegenden Erfindung eine einseitige Richtwirkung dadurch erzielen, dass man hinter dem Antennensystem, das aus mehreren Antennen besteht, eine reflektierende Ebene anordnet.

   Eine Anordnung, wie sie dem Sinne der Erfindung entsprechen würde, ist schematisch in der beiliegenden Figur skizziert. 1, 2, 3 und 4 seien vier Antennen bzw. Antennenkombinationen, die in ihrer Zusammenwirkung eine lemniskatenförmige Charakteristik ergeben würden. Diese Charakteristik ist   punktiert eingezeichnet. Um   nun eine einseitige Richtwirkung in der Richtung   A   zu erzielen, ist hinter der Antennenanordnung ein Reflektor B aufgestellt. Dieser Reflektor kann aus geeignet abgestimmten antennenartigen Gebilden bestehen.

    Multiple antenna arrangement for sending short waves.



   It is known that by using a plurality of antennas which are arranged at a certain distance from one another and optionally oscillate with appropriate phase shifts, a transmission system with pronounced directional effect is obtained. By combining several high antennas, which are set up along a straight line, an antenna system with two-sided directional effect is obtained. In order to produce a unilateral directional effect, it is known that combinations of directional and non-linear antennas are used. If, on the other hand, one works with short waves, a one-sided directional effect can be achieved according to the present invention by arranging a reflecting plane behind the antenna system, which consists of several antennas.

   An arrangement that would correspond to the meaning of the invention is sketched schematically in the accompanying figure. 1, 2, 3 and 4 are four antennas or antenna combinations which, when combined, would result in a lemniscate-like characteristic. This characteristic is shown in dotted lines. In order to achieve a one-sided directivity in direction A, a reflector B is placed behind the antenna arrangement. This reflector can consist of appropriately matched antenna-like structures.
