Der Erfindung liegt die Aufgabe zugrunde, eine Antenne zu schaffen, die den Erfordernissen des digitalen Fernsehens entsprichtThe invention has for its object to provide an antenna that meets the requirements of digital television

Diese Aufgabe wird mit der in den Patentansprüchen definierten Antenne gelöst.This object is achieved with the antenna defined in the claims.

Die Erfindung weist eine Mehrzahl von Vorteilen auf.The invention has a plurality of advantages.

Die Antenne ist erfindungsgemäß in der Weise ausgestaltet, dass eine zugeordnete Impedanzadapterschaltung und eine zugeordnete, in Serie geschaltete Verstärkungsschaltung eine schaltungstechnische Einheit bilden. Die Verstärkungsschaltung weist eine Verstärkungsstufe und eine Durchgangsschaltung auf, die zu der Verstärkungsstufe parallel geschaltet und mit dieser verbunden ist. Die Impedanzadapterschaltung und die Verstärkungsschaltung bilden weiterhin in der Weise eine schaltungstechnische Einheit, dass im Fall eines Ausfalls der Verstärkungsstufe und/oder im Fall des Nicht-Anschlusses der schaltungstechnischen Einheit an eine Speisequelle der Betrieb der schaltungstechnischen Einheit dem Betrieb der Impedanzadapterschaltung entspricht.
Die erfindungsgemäße Antenne ist damit selbst nach einem Ausfall der Verstärkerschaltung nutzbar; die erfindungsgemäße Antenne entspricht in diesem Betriebsfall einer Antenne, der keine Verstärkungsschaltung zugeordnet ist.
Die Impedanzadapterschaltung und die Verstärkungsschaltung sind miteinander verbunden und vorzugsweise in einem gemeinsamen Gehäuse angeordnet, wobei das Gehäuse an der Antenne angeordnet und abgeschirmt ist. Damit wird der geometrische Abstand zwischen der eigentlichen Antenne und den genannten Schaltungen (Impedanzadapterschaltung, Verstärkungsschaltung) minimiert und die Verarbeitung der von der Antenne empfangenen Signale bzw. der Antennengewinn optimiert. Die Signale werden verstärkt, ohne dass die Rauschzahl verschlechtert wird. Die erfindungsgemäße Antenne ist damit auch in Zonen vergleichsweise schwachen Empfangs nutzbar. Insbesondere ist das Gehäuse gegen mögliche Störsignale abgeschirmt.According to the invention, the antenna is designed in such a way that an associated impedance adapter circuit and an associated amplification circuit connected in series form a circuit unit. The amplification circuit comprises a gain stage and a pass circuit connected in parallel with and connected to the amplification stage. The impedance adapter circuit and the amplification circuit furthermore form a circuit unit in such a way that, in the event of a failure of the amplification stage and / or in the case of non-connection of the circuit unit to a supply source, the operation of the circuit unit corresponds to the operation of the impedance adapter circuit.
The antenna according to the invention can thus be used even after a failure of the amplifier circuit; In this case of operation, the antenna according to the invention corresponds to an antenna to which no amplification circuit is assigned.
The impedance adapter circuit and the amplification circuit are connected together and preferably arranged in a common housing, wherein the housing is arranged on the antenna and shielded. This minimizes the geometric distance between the actual antenna and the circuits mentioned (impedance adapter circuit, amplification circuit) and optimizes the processing of the signals received by the antenna or the antenna gain. The signals are amplified without degrading the noise figure. The antenna according to the invention is thus also usable in zones of comparatively weak reception. In particular, the housing is shielded against possible interference signals.

Zugleich wird eine kompakte, mechanisch einfache Ausgestaltung der Schaltungstechnik erzielt, so dass sich die Einheit in einfacher Weise an der Antenne anordnen lässt bzw. in diese integrieren lässt.At the same time a compact, mechanically simple design of the circuit technology is achieved, so that the unit can be arranged in a simple manner to the antenna or can be integrated into this.

Die Speisequelle ist insbesondere durch ein Solarzellensystem gebildet. Neben dem ökologischen Vorteil dieser Lösung besteht ein weiterer Vorteil darin, dass die Antenne damit ohne eine externe Speisequelle betrieben werden kann, die zudem über eine Zuleitung mit der Verstärkungsschaltung zu verbinden wäre.The feed source is formed in particular by a solar cell system. In addition to the ecological advantage of this solution, another advantage is that the antenna can thus be operated without an external supply source, which would also be connected via a supply line to the amplification circuit.

Dieses Gehäuse weist vorzugsweise einen Steckverbinder auf für einen direkten oder indirekten Anschluss an ein Empfangsgerät für Fernsehen, Rundfunk und/oder Daten. Insbesondere sind das Gehäuse und der Steckverbinder einstückig ausgebildet. Mit diesen Ausgestaltungen wird eine bessere Anpassung zwischen der Antenne einerseits und den Empfangsgeräten andererseits erzielt; Reflexionseffekte auf die Signale werden praktisch ausgeschlossen.This housing preferably has a connector for direct or indirect connection to a television, radio and / or data receiver. In particular, the housing and the connector are integrally formed. With these embodiments, a achieves better matching between the antenna on the one hand and the receivers on the other hand; Reflection effects on the signals are virtually eliminated.

Dies ermöglicht es, die Strahlungsoberfläche des Dipols zu vergrößern, wodurch verbesserte Gewinneigenschaften der Antenne erzielt werden.FIG. 3 shows in detail the dipole 13 of the antenna, which is composed of two parts 131 in U-shape, which have folds 134 on their broad side. This makes it possible to increase the radiation surface of the dipole, thereby achieving improved gain characteristics of the antenna.

Die Teile 131 weisen an ihrer Basis jeweils eine Flosse 132 in L-Form auf, wobei die Basis jeweils ein Faltteil aufweist, in dem sich jeweils eine Ă–ffnung 133 zum Verbinden des Dipols befindet.The parts 131 each have at their base a fin 132 in L-shape, the base each having a folding part, in each of which there is an opening 133 for connecting the dipole.

Der Dipol kann in mehr als einer Ebene ausgebildet sein. Damit wird die Oberfläche des Dipols vergrößert, ohne die Länge des Dipols zu vergrößern; Frequenzabstimmwerte der Antenne werden beibehalten.The dipole may be formed in more than one plane. This enlarges the surface of the dipole without increasing the length of the dipole; Frequency tuning values of the antenna are retained.

Der Dipol kann auch mit einem ebenen Profil ausgestaltet sein, was ein Erweitern der Antennenbandbreite erlaubt.The dipole may also be configured with a planar profile, which allows extending the antenna bandwidth.

Figur 4 zeigt das Gehäuse 14, das aus einem rechtwinkligen Körper (Basis)141 und einem Deckel 142 besteht, wobei Basis und Deckel mittels Gewindeschrauben verschlossen werden, die durch Aussparungen 144 des Deckels geführt und in Öffnungen 143 der Basis eingeführt werden. Die Basis hat in ihrem Innenraum Bolzen 145, auf die eine Leiterplatte mit einer elektronischen Schaltung, insbesondere mit der Verstärkungsschaltung 16 und der Impedanzanpassungsschaltung aufgesetzt wird.Figure 4 shows the housing 14, which consists of a rectangular body (base) 141 and a lid 142, wherein the base and lid are closed by means of threaded screws, which are guided through recesses 144 of the lid and inserted into openings 143 of the base. The base has in its interior bolt 145, on which a circuit board with an electronic circuit, in particular with the amplification circuit 16 and the impedance matching circuit is placed.

Das Gehäuse 14 nimmt die Impedanzadapterschaltung 15 und die Verstärkungsschaltung 16 auf; das Gehäuse 14 ist unmittelbar an der Antenne angeordnet bzw. in diese integriert. Es besteht aus elektrisch leitendem Material und ist mit Masse verbunden.The housing 14 accommodates the impedance adapter circuit 15 and the amplification circuit 16; the housing 14 is disposed directly on the antenna or integrated into it. It consists of electrically conductive material and is connected to ground.

Die Basis 141 des Gehäuses 14 weist in einer seiner Seitenwände einen Steckverbinder (Buchse) 21 für einen direkten oder indirekten Anschluss an einen Fernseh-, Radio- und/oder Datensignalempfänger auf. Der Verbinder 21 und das Gehäuse 4 sind einstückig ausgebildet. Damit wird eine vergleichsweise gute elektrische Anpassung zwischen den Empfangsgeräten und der Antenne, mögliche Störsignale werden in ihrer Wirkung begrenzt.The base 141 of the housing 14 has in one of its side walls a connector (socket) 21 for direct or indirect connection to a television, radio and / or data signal receiver. The connector 21 and the housing 4 are integrally formed. This is a comparatively good electrical matching between the receivers and the antenna, possible interference signals are limited in their effect.

Die Basis des Gehäuses 14 weist zwei Öffnungen 146 auf, durch die Zapfen 191 geführt sind, die zur Stütze 19 des Gehäuses gehören. Diese Zapfen 191 haben Innenöffnungen, in denen Schrauben angeordnet sind, die die elektrische Verbindung zwischen dem Dipol 13 und der Verstärkungsschaltung 16, der in dem Gehäuse 14 angeordnet ist, herstellen.The base of the housing 14 has two openings 146, are guided by the pins 191, which belong to the support 19 of the housing. These pins 191 have internal openings in which screws are arranged, which establish the electrical connection between the dipole 13 and the amplifying circuit 16, which is arranged in the housing 14.

Ausgehend von der ebenen Basis 192 steigen vertikal paarweise Wände 193 und 194 auf, die in Klammerzähnen 195 und 196 enden. Diese greifen in die Zentralstange 1 bzw. in die Fenster 48 des Hinterradoms 4 (Fig. 2) ein, und bilden einen Sitz bilden für die Einheit, die durch den Dipol 13, das Gehäuse 14 und die Stütze 19 des Gehäuses im Innern der Aussparung 47 (Fig. 2) des Hinterradoms 4 gebildet ist.Starting from the planar base 192, vertical pairs of walls 193 and 194 rise, ending in bracket teeth 195 and 196. These engage in the central bar 1 and in the windows 48 of the rear wheel 4 (Figure 2), and form a seat for the unit passing through the dipole 13, housing 14 and support 19 of the housing inside the recess 47 (Fig. 2) of the rear wheel 4 is formed.

Figur 5 zeigt das Schaltbild des Anpassschaltung 15 und der elektrischen Verstärkungsschaltung 16.FIG. 5 shows the circuit diagram of the matching circuit 15 and the electrical amplification circuit 16.

Die Anpass-Schaltung 15 ist mittels der gedruckten Leitung J1 gebildet.The matching circuit 15 is formed by the printed line J1.

Die elektrische Verstärkungsschaltung 16 ist wie folgt ausgestaltet. Sie weist ein erstes Filter, das heißt ein Hochpassfilter auf, das durch die Kondensatoren C1, C2 und C6, die Diode D3 und die Spule CH2 gebildet ist. Weiterhin weist sie eine Verstärkungsstufe auf, die aus dem Transistor T1 und seinem Polarisierkreis, bestehend aus den Widerständen R1, R2, R3, R4 und R6, den Kondensatoren C3 und C4, und den Spulen L1 und CH1 gebildet ist. Weiterhin weit die Schaltung 16 eine Ausgangsstufe auf, die aus den Kondensatoren C5, C11, C8 und den Spulen CH3 und CH5 gebildet ist.The electrical amplification circuit 16 is configured as follows. It has a first filter, that is to say a high-pass filter, which is formed by the capacitors C1, C2 and C6, the diode D3 and the coil CH2. Furthermore, it has an amplification stage which is formed by the transistor T1 and its polarizing circuit consisting of the resistors R1, R2, R3, R4 and R6, the capacitors C3 and C4, and the coils L1 and CH1. Furthermore, the circuit 16 has an output stage formed of the capacitors C5, C11, C8 and the coils CH3 and CH5.

Die elektrische Verstärkungsschaltung 16 weist elektrische Schaltwege auf, eine Durchgangsschaltung und eine Schutzschaltung auf.The electric booster circuit 16 has electrical switching paths, a pass circuit, and a protection circuit.

Die Durchgangsschaltung wird durch die Kondensatoren C7, C9 und C14, durch die Dioden D1 und D2, die Kapazitätsdiode (Varicap) D5, die Widerstände R5 und R8 und durch eine gedruckte Leitung J2 gebildet. Diese Durchgangsschaltung gestattet den Durchlaß des Signals, sobald der Verstärkungsstufe keine Stromspeisung zugeführt wird.The pass circuit is formed by the capacitors C7, C9 and C14, by the diodes D1 and D2, the varicap D5, the resistors R5 and R8, and a printed line J2. This pass circuit allows the passage of the signal as soon as the power amplifier is not supplied with power.

Die Schutzschaltung umfasst eine Diode D4 und einen Widerstand R9. Diese Schutzschaltung führt das Signal zum Ausgang, das die Durchgangsschaltung (C7, C9, C14, D1, D2, D5, R5, R8, J2) durchläuft, wenn die Verstärkungsstufe keine Stromspeisung hat, was vermeidet, dass dieses Signal zum Polarisierkreis des Transistors T1 abgeleitet wird.The protection circuit comprises a diode D4 and a resistor R9. This protection circuit passes the signal to the output which passes through the pass circuit (C7, C9, C14, D1, D2, D5, R5, R8, J2) when the amplification stage has no current supply, which avoids that signal to the polarization circuit of the transistor T1 is derived.

Die Verstärkungsstufe wird über den Ausgangssteckverbinder der Antenne (21 in Figur 4, entsprechend der galvanischen Verbindung RF_OUT+Vcc in Figur 5) gespeist, und zwar mittels eines Koaxialkabels, das die Antenne mit den übrigen Einrichtungen des Systems verbindet. Die Speisespannung kann von Kopfeinheiten, die auf dem Markt verfügbar sind und bereits hierfür ausgelegt sind, oder über das Koxialkabel zugeführt werden.The amplification stage is fed via the output connector of the antenna (21 in Figure 4, corresponding to the galvanic connection RF_OUT + Vcc in Figure 5) by means of a coaxial cable which connects the antenna to the other devices of the system. The supply voltage can be from head units, which are available on the market and already designed for this, or are supplied via the Koxialkabel.

Der Verstärkungsschaltung 16 ist in der unmittelbaren Nähe des Impedanzadapterschaltung 15 angeordnet (kein geometrischer Abstand zwischen 16 und 15, bzw. 0 Millimeter).The amplification circuit 16 is located in the immediate vicinity of the impedance adapter circuit 15 (no geometric distance between 16 and 15, or 0 millimeter).

Der Impedanzadapterschaltung 15 und der Verstärkungsschaltung 16 bilden eine schaltungstechnische Einheit, wobei der Betrieb der Einheit im Falle eines Ausfalls der Verstärkungsschaltung 16 (Ausfall mindestens einer Schaltungskomponente; keine Versorgungsspannung) dem Betrieb der Impedanzadapterschaltung 15 entspricht.The impedance adapter circuit 15 and the amplification circuit 16 form a circuit unit, wherein the operation of the unit in the event of failure of the amplification circuit 16 (failure of at least one circuit component, no supply voltage) corresponds to the operation of the impedance adapter circuit 15.

Die oben beschriebene Positionierung eines Verstärkers an der Antenne ist an sich mit dem Nachteil verbunden, dass der Verstärker Witterungseinflüssen ausgesetzt ist, die zu einer Funktionseinschränkung bzw. zu einer Zerstörung des Verstärkers führen können. So kann beispielsweise Regen, der in das Verstärkergehäuse eindringt, Kurzschlüsse und eine Zerstörung von Schaltungskomponenten bewirken. Ein weiteres Beispiel ist eine elektrische Entladung, die eine Überspannung in der Verstärkungsschaltung und ein Verbrennen von Schaltungskomponenten bewirkt.The above-described positioning of an amplifier on the antenna is inherently associated with the disadvantage that the amplifier is exposed to the effects of the weather, which can lead to a functional restriction or to the destruction of the amplifier. For example, rain that enters the amplifier housing can cause short circuits and destruction of circuit components. Another example is an electrical discharge that causes overvoltage in the amplification circuit and burning of circuit components.

In der Verstärkungsschaltung gemäß Figur 5 wird die Wahrscheinlichkeit hierfür durch die Schutzschaltung reduziert, die aus den Kondensatoren C1 und C2, aus der Spule CH2 und aus der Diode D3 besteht. Diese sind in der Weise ausgestaltet, dass Überspannungen absorbiert werden, die durch eine mögliche Strahlung bewirkt werden können, die die Antenne erreichen. Die Komponenten, die vergleichsweise stark gefährdet sind, sind Halbleiterkomponenten, hier der Transistor T1, die Dioden D1, D2, D4 und die Varicapdiode D5. Der Ausfall des Transistors T1 würde zum Ausfall der Verstärkerschaltung führen. Der Ausfall der Diode D4 würde an sich dazu führen, dass die Verstärkerschaltung weiter arbeitet, aber auch dazu, dass sie vom Ausgang der Schaltung getrennt wird, was im Ergebnis die Nichtverfügbarkeit des Verstärkers bedeutet. Der Ausfall der beiden Dioden D1 und D2 würde dazu führen, dass der Verstärker in einen Schwingungszustand versetzt wird. Der Ausfall der Varicapdiode D5 würde den Betrieb des Verstärkers nicht beeinflussen. Während üblicherweise der Ausfall einer Schaltungskomponente des Verstärkers die Antenne außer Funktion setzt und erfordert, dass die Antenne bzw. die Schaltung ersetzt wird, ist die erfindungsgemäße Schaltung in der Weise ausgestaltet, dass bei Ausfall des Verstärkers die Antenne als konventionelle Antenne weiter genutzt werden kann; die Adapterschaltung bleibt weiter mit dem Ausgangssteckverbinder über die Leitung J2 und über die Anordnung von C14 und Diode D5 verbunden. Es ist bei Bedarf nur die Speisespannungsquelle zu deaktivieren.In the amplification circuit according to FIG. 5, the probability for this is reduced by the protection circuit which consists of the capacitors C1 and C2, of the coil CH2 and of the diode D3. These are designed in such a way that surges are absorbed, which can be caused by a possible radiation reaching the antenna. The components that are relatively at risk are semiconductor components, here the transistor T1, the diodes D1, D2, D4 and the varicap diode D5. The failure of the transistor T1 would lead to failure of the amplifier circuit. The failure of diode D4 would in itself cause the amplifier circuit to continue to operate but also to be disconnected from the output of the circuit, resulting in the unavailability of the amplifier as a result. The failure of the two Diodes D1 and D2 would cause the amplifier to vibrate. The failure of the Varicapdiode D5 would not affect the operation of the amplifier. While usually the failure of a circuit component of the amplifier disables the antenna and requires that the antenna or circuit be replaced, the circuit according to the invention is designed in such a way that the antenna can be used as a conventional antenna in case of failure of the amplifier; the adapter circuit remains connected to the output connector via line J2 and through the array of C14 and diode D5. If necessary, only deactivate the supply voltage source.

Die schaltungstechnische Einheit, bestehend aus den Schaltungen 15 und 16, fungiert im Normalbetrieb, wenn sie mit der entsprechenden Spannung versorgt wird, als Impedanzanpassungs- und als Verstärkungsschaltung. Dabei verringert sich die Kapazität von D5, wenn die Spannung eingangsseitig erhöht wird. D1 und D2 werden leitend. Damit wird unterbunden, dass ein Signal über J2 geführt wird, da C14 zusammen mit D5 eine große Impedanz bilden, während das Restsignal über C9 und C7 an Masse geführt wird. Insgesamt wird erreicht, dass das von der Antenne empfangene Signal über die Verstärkerstufe geführt wird. Ein Schwingungszustand wird vermieden. Schließlich vermöglicht die Diode D4, wenn sie gespeist wird, dass das Signal des Verstärkers zu dem Ausgang geführt wird.The circuit unit, consisting of the circuits 15 and 16, functions in normal operation when supplied with the corresponding voltage, as impedance matching and as amplification circuit. This reduces the capacitance of D5 when the voltage on the input side is increased. D1 and D2 become conductive. This prevents a signal from being passed through J2, since C14 together with D5 form a large impedance, while the rest of the signal is routed to ground via C9 and C7. Overall, it is achieved that the signal received by the antenna is passed through the amplifier stage. A vibration condition is avoided. Finally, when energized, diode D4 allows the amplifier's signal to be routed to the output.

Die schaltungstechnische Einheit, bestehend aus den Schaltungen 15 und 16, fungiert, wenn sie nicht mit der entsprechenden Spannung versorgt wird, als Impedanzanpassungsschaltung. In diesem Fall gelangt das Signal von J1 zum Ausgang und zwar über J2 und die Anordnung von J14 und D5, die eine große Kapazität aufweist, wenn der Einheit keine Spannung zugeführt wird. Die Dioden D1 und D2 verhindern, dass das Signal über C9 bzw. C7 abgeleitet wird; die Diode D14 übt dieselbe Funktion hinsichtlich des Kollektors des Transistors T1 und der Elemente CH1, R3, C4, R4, R6 und C8. Die Elemente L1, R1 und C3 verhindern den Verlust des Signals über den Eingang des Verstärkers.The circuit unit consisting of the circuits 15 and 16, when not supplied with the corresponding voltage, functions as the impedance matching circuit. In this case, the signal passes from J1 to the output through J2 and the arrangement of J14 and D5, which has a large capacitance when no voltage is supplied to the unit. The diodes D1 and D2 prevent the signal from being diverted via C9 and C7, respectively; the diode D14 performs the same function with respect to the collector of the transistor T1 and the elements CH1, R3, C4, R4, R6 and C8. The elements L1, R1 and C3 prevent the loss of the signal through the input of the amplifier.
