Description

Gegenstand der Erfindung ist eine rechteckige Unterleg-Filzmatte mit eingelegter Ultrakurzwellen-Faltdipolantenne für Rundfunkempfangsgeräte.The invention relates to a rectangular felt mat with inserted ultra-short wave folding dipole antenna for radio receivers.

Unterleg-Filzmatten mit einfachen Antennendrahteinlagen und seitlichem Anschluß für Rundfunkgeräte sind bekannt.Underlay felt mats with simple antenna wire inserts and on the side Connections for radio devices are known.

Demgegenüber besteht das Neue beim Erfin dungsgegenstand in der Anordnung bzw. Führung der Faltdipoldrahteinlage, die insofern von der be kannten rechteckigen Form abweicht, als die Doppelführung an den beiden Schmalseiten der Matte zur Mitte hin haarnadelförmig eingezogen und an den gegenüberliegenden Breitseiten der Matte parallel verläuft, wobei die Doppelleitung auf der einen Breitseite unterbrochen ist und beide Enden in sich kurzgeschlossen sind, während auf der anderen Breitseite der Matte nur ein Draht unterbrochen und die gegenüberliegenden Enden der Unterbrechungsstelle nach außen zum Empfänger geführt werden.In contrast, what is new in the subject matter of the invention is the arrangement or leadership of the Faltdipolrahteinlage, which insofar from the known rectangular Shape deviates than the double guide on the two narrow sides of the mat towards the middle drawn in like a hairpin and on the opposite broad sides of the mat runs in parallel, with the double line interrupted on one broad side is and both ends are short-circuited, while on the other broadside the mat only interrupted one wire and the opposite ends of the interruption point out to the recipient.

Durch die vorgeschlagene Linienführung des Faltdipols wird ein nahezu gleichmäßiger Empfang in jeder Lage und Stellung der Filzmatte erreicht, weil die Ultrakurzwellen stets einen mehr oder weniger großen Abschnitt des Faltdipols empfangsrichtig beeinflussen. Hierdurch entfällt die sonst erforderliche Ausrichtung zum UKW-Sender. Ungeachtet der erfindungsgemäßen Führung des Faltdipols kann dieser auch für normalen Rundfunkwellenempfang benutzt werden.Due to the proposed lines of the folding dipole, a nearly uniform reception is achieved in every position and position of the felt mat because the Ultra-short waves always receive a more or less large section of the folded dipole influence. This eliminates the need for alignment with the VHF transmitter. Regardless of the inventive guidance of the folding dipole, this can also be used for normal Radio wave reception can be used.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung veranschaulicht; es zeigt Abb. r eine Draufsicht auf die Unterleg-Filzmatte mit offenliegender Faltdipolantennenführung, Abb. 2 einen Schnitt nach der Linie A- A der Abb. r .An embodiment of the subject matter of the invention is illustrated in the drawing; it shows Fig. r a top view of the felt mat with exposed folding dipole antenna guide, Fig. 2 a section along the line A-A of Fig. r.

Innerhalb der Filzmatte t ist der Faltdipol 2 angeordnet, der an den beiden Schmalseiten der Matte bei 2a haarnadelförmig zur Mitte der Matte hin verläuft. Auf der einen Breitseite der Matte ist der Faltdipol 2b unterbrochen und bei 2e kurzgeschlossen. Auf der anderen Breitseite bei 2d ist nur ein Drahtdes Dipols unterbrochen, während die beiden Enden 2e der Unterbrechungsstelle nach außen zum Empfänger geführt werden.Within the felt mat t, the folding dipole 2 is arranged, which is attached to the both narrow sides of the mat at 2a hairpin-shaped towards the center of the mat. The folding dipole 2b is interrupted on one broad side of the mat and at 2e shorted. On the other broad side at 2d only one wire of the dipole is interrupted, while the two ends 2e of the interruption point outwards to the receiver will.
