Anordnung für Mehrfachempfang mit einem aperiodischen Richtantennensystem.Arrangement for multiple reception with an aperiodic directional antenna system.
Patentiert im Deutschen Reiche vom 28. Juni 1923 ab.Patented in the German Empire on June 28, 1923.
Es war bekannt, bei Empfangseinrichtungen in der drahtlosen Telegraphie und TeIephonie aperiodische Antennen zn verwenden, an die auf mehrere Frequenzen abgestimmte Empfangsapparaturen angeschlossen wurden, um den gleichzeitigen Empfang mehrerer Wellen zu ermöglichen. Zur Vermeidung· der Rückwirkung wurden in solchen Fällen die Empfänger über Elektronenröhren an die Antennen angeschlossen.It was known to be used in receivers in wireless telegraphy and telephony Use aperiodic antennas zn tuned to several frequencies Receiving apparatuses were connected to the simultaneous reception of several Allow waves. To avoid retroactive effects, the Receiver connected to the antennas via electron tubes.
Gemäß der vorliegenden Erfindung wird ein gleichzeitiger gerichteter Empfang für mehrere Frequenzen erreicht,, und zwar derart, daß für jede aufzunehmende Welle die Antennenanordnung eine einseitige Richtwirkung besitzt. Zu diesem Zweck wird eineAccording to the present invention, simultaneous directional reception for reached several frequencies, in such a way that for each wave to be recorded the Antenna arrangement has a unilateral directional effect. For this purpose a
aperiodische Richtantenne verwendet, beispielsweise ein gewöhnlicher Rahmen. Von dieser Richtantenne werden die Rahmeneffekte für die einzelnen Wellen den entsprechenden Empfangskreisen zugeführt, und außerdem wird auf jeden Empfangskreis noch ein Hochantenneneffekt übertragen, indem für jede aufzunehmende Welle eine besondere Hochantenne vorgesehen ist.aperiodic directional antenna is used, for example an ordinary frame. from this directional antenna, the frame effects for the individual waves are the corresponding Receiving circuits fed, and also a high antenna effect is still on each receiving circuit transmitted by providing a special high antenna for each wave to be recorded.
ίο In der Abb. ι ist eine Anordnung dargestellt, mit der ein gleichzeitiger einseitiger Richtempfang für verschiedene Wellen (X1, X2 und X3) erzielt wird. Von dem Rahmen werden die Rahmeneffekte über ein gemeinsames Kabel K. und reaktionslose Röhrenkopplungen, die in der Zeichnung mit c angegeben sind, den einzelnen Empfängerkreisen 1, 2 und 3 zugeführt. Für die Antenneneffekte sind besondere Hochantennen A2 und A3 vorgesehen, während für eine Welle nach der Figur X1 als Hochantenne der geerdete Rahmen A1 benutzt wird. Diese Antenneneffekte gelangen über die Kabel K1, AT2 und ΑΓ3 in die Empfängerkreise 1, 2, 3, so daß durch phasen- und amplitüdenrichtige Kombination der beiden Effekte ein einseitiger Richtempfang für jede Welle im entsprechenden Empfänger ermöglicht ist.ίο In Fig. ι an arrangement is shown with which a simultaneous one-sided directional reception for different waves (X 1 , X 2 and X 3 ) is achieved. The frame effects are fed from the frame to the individual receiver circuits 1, 2 and 3 via a common cable K. and non-reactive tube couplings, which are indicated by c in the drawing. Special high antennas A 2 and A3 are provided for the antenna effects , while the grounded frame A 1 is used as the high antenna for a wave according to FIG. X 1. These antenna effects reach the receiver circuits 1, 2, 3 via the cables K 1 , AT 2 and ΑΓ3, so that a one-sided directional reception for each wave in the corresponding receiver is made possible by combining the two effects with the correct phase and amplitude.
In der praktischen Ausführung wird als aperiodische Richtantenne im allgemeinen ein Kreuzrahmen verwendet, wie er in der Abb. 2 dargestellt ist. K stellt die beiden Kreuzrahmen dar, die das Empfangsantennensystem bilden. Von diesen Rahmen werden die anj kommenden Schwingungen in bekannter Weise j über die beiden Kabel α und b weitergeführt. ! Vom Ende der Kabel wird die aufgenommene Energie über mehrere reaktionslose Koppj lungseinrichtungen, die mit c bezeichnet sind, mehreren Empfangsgoniometern (t, m und ti) zugeführt. Die Kreuzrahmen und; die Kabel sind aperiodisch und können somit zur Übertragung mehrerer Frequenzen dienen. Da die Abstimmelemente für die verschiedenen Frequenzen erst hinter den Empfangsgoniometem angeordnet sind, diese Empfangsgoniometer a.be,r über reaktionslose Röhrenkopplungen an (das .Antennensystem angeschlossen "sind, so werden schädliche Rückwirkungen der auf verschiedene Frequenzen abgestimmten Empfangskreise vermieden.In practice, a cross frame, as shown in FIG. 2, is generally used as the aperiodic directional antenna. K represents the two cross frames that form the receiving antenna system. From this frame the incoming vibrations are carried on in a known manner j via the two cables α and b . ! From the end of the cable, the absorbed energy is fed to several receiving goniometers (t, m and ti) via several non-reactive coupling devices, which are labeled c. The cross frame and; the cables are aperiodic and can therefore be used to transmit multiple frequencies. Since the tuning elements for the various frequencies are only arranged behind the receiving goniometers, these receiving goniometers a.be, r are connected to (the antenna system) via non-reactive tube couplings, thus avoiding harmful repercussions of the receiving circuits tuned to different frequencies.
