Abstract

HF and UHF aerial for radio receiver with scale and instrument illumination. The line supplying the current to the dial illuminating lamp is used as the aerial. The illuminating bulb is clamped between two terminal fittings. The two terminals are coupled by a capacitor. One end of the supply line is connected directly to the capacitor and the other end to the lamp voltage via chokes and via capacitors to the input circuit of the radio receiver. The supply line is laid out like a rectangular frame. The function of the capacitor across the bulb terminals is to short circuit the HF components.

Description

KW- und UKW-Antenne für Rundfunkempfangsgeräte mit Skalen- und Gerätebeleuchtung Die Erfindung betrifft eine. KW- und UKW-Antenne für Rundfunkempfangsgeräte mit Skalen- und Gerätebeleuchtung.HF and VHF antenna for radio receivers with dial and device lighting The invention relates to a. HF and VHF antenna for radio receivers with Scale and device lighting.

Es ist bereits bekannt, bei Rundfunkempfangsgeräten für den KW- und UKW-Betrieb Stabantennen vorzusehen, die einen elektrischen Dipol darstellen. Befindet sich ein solcher Dipol im elektHischen Wechselfeld; so ist seine Leerlaufspannung durch die Potentiale der Leitermittelpunkte bestimmt. Nachteilig ist bei diesen bekannten Stab-Antennen, daß sie leicht abbrechen können, daß man sich an ihnen verletzen kann und daß zwischen Ihnen und den Rundfunk-Empfangseinrlchtungenschwer sichere elektrische Kontakte hergestellt werden können. Hinzu kommt noch, daß starre oder teleskopartig herausziehbare Stabantennen ästhetisch nicht sehr schön wirken.It is already known in radio receivers for the KW and VHF operation to provide rod antennas that represent an electric dipole. Located Such a dipole is located in an alternating electrical field; so is his Open circuit voltage determined by the potentials of the conductor centers. Disadvantageous is with these known rod antennas that they can easily break off that one can injure yourself on them and that it is difficult to get between you and the radio reception equipment safe electrical contacts can be established. There is also the fact that it is rigid or telescopic rod antennas do not look very aesthetically pleasing.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine KW- und UKW-Antenne zu schaffen, die innerhalb eines Rundfunkempfangsgerätsangeordnet werden kann und die vorgenannten Nachteile nicht aufweist.The invention is therefore based on the object of a HF and VHF antenna to create that can be placed within a broadcast receiving apparatus and does not have the aforementioned disadvantages.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst,daß die Stromzuführungsleitung zur Skalenbeleuchtungsiampe als Antenne vorgesehen ist.This object is achieved according to the invention in that the power supply line is provided as an antenna for the scale illumination lamp.

Der mit der Erfindung erzielte Vorteil besteht Insbesondere darin, daß statt einer Stromzuführungsleitung für die Skalenbeleuchtungslampe und einer davon getrennten Stabantennen nur noch eine Einrichtung vorgesehen ist, welche beide Funktlonen erfüllt.The advantage achieved with the invention consists in particular in that instead of a power supply line for the scale illumination lamp and one separate rod antennas only one device is provided, which both Functions fulfilled.

Ein Ausführungsbeispiel der Erfindung Ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben..An embodiment of the invention is shown in the drawing and is described in more detail below.

Die einzige Figur zeigt eine Skalenbeleuchtungslampe 1, welche mit einer Stromzuführungsleitung 2 elektrisch verbunden ist. Eine derartige Skalenbeleuchtungslampe kann etwa in einem Gerät verwendet werden, wie es in der Patentanmeldung P 24 05 387.0 beschrieben ist. Die Halterung der Lampe 1 erfolgt durch Klemmstücke 3, 4, die über einen Kondensator 5 miteinander verkoppelt sind. Die Stromzuführungsleitung 2 ist auf der einen Seite unmittelbar an den Kondensator 5 und auf der anderen Seite über Drosseln 6, 7 mit der Lampenspannung bzw. über Kondensatoren 8, 9 mit dem Eingangsschaltungen eines Rundf,unkempfangsgeräts verbunden.The single figure shows a scale illumination lamp 1, which with a power supply line 2 is electrically connected. Such a dial illumination lamp can be used in a device as described in patent application P 24 05 387.0 is described. The lamp 1 is held by clamping pieces 3, 4, which are coupled to one another via a capacitor 5. The power supply line 2 is on one side directly to the capacitor 5 and on the other side via chokes 6, 7 with the lamp voltage or via capacitors 8, 9 with the input circuits of a broadcast radio receiver.

Trifft ein elektromagnetlsches Wechselfeld auf dle StromzufUhrungsleitung 2, so entsteht in dieser Leitung 2 etne-hochfrequente Wechselspannung, für welche die Kondensatoren 5, 8, 9 elnen elektrischen Kurzschluß darstellen. Die gesamte hochfrequente Wechselspannung steht somit als Antennenspannung zur weIteren Verarbeitung, z.B. Demodulation und Verstärkung, an den Elngangsschaltungen des Rundfunkempfangsgerätes an.If an alternating electromagnetic field strikes the power supply line 2, there is 2 etne high-frequency alternating voltage in this line, for which the capacitors 5, 8, 9 represent an electrical short circuit. The whole high-frequency alternating voltage is therefore available as antenna voltage for further processing, e.g. demodulation and amplification on the input circuits of the radio receiver at.

Eine Auswirkung der hochfrequenten Wechsel spannung auf die niederfrequente Lampensp3nnungs-Quelle wird dadurch vermieden, daß die Drosseln 6 , 7 vorgesehen sind, Welche für hochfrequente Wechselspannungen als Sperre wirken.An effect of the high-frequency alternating voltage on the low-frequency Lamp voltage source is avoided in that the chokes 6, 7 are provided are, which act as a barrier for high-frequency alternating voltages.

Ist die Lampe 1 beispielswelse in einem Gehäusedeckel untergebracht, wie es in der Patentanmeldung P 24 05.387.0 gezeigt ist, so können die spannungsführenden Leitungen über eine stromleitende Rutschkupplung mit den elektrischen Bauteilen des Gehäuses verbunden werden.For example, if the lamp 1 is housed in a housing cover, As shown in patent application P 24 05.387.0, the live Lines via a conductive slip clutch with the electrical components of the housing.
