Abstract

The invention concerns a space craft, such as a telecommunication geostationary satellite, comprising a body, at lease one main telecommunication antenna having a specific orientation relative to the body, at least an omnidirectional antenna having a field of view opposite to that of the main antennae and at least a radiator extensible by tilting about an axis linked to the craft body between a slowing position wherein it is pressed against the body and an extended position. Said axis is positioned substantially in the plane of one surface of the body parallel to the orientation of the omnidirectional antenna and to the surfaces or the surface bearing the main antenna. The radiator tilts at an angle close to 180 o from a position wherein it is pressed against one surface bearing a solar panel to a position wherein it extends substantially in the plane of the surface which bears it when it is slowed.

Description

DACHANTENNE FÜR KRAFTFAHRZEUGEROOF ANTENNA FOR MOTOR VEHICLES
Die Erfindung betrifft eine Antennenanordnung nach dem Oberbegriff des Anspruches 1.The invention relates to an antenna arrangement according to the preamble of claim 1.
Eine gattungsbildende Antennenanordnung ist beispielsweise aus der DE 201 11 229 U 1 bekannt geworden. In dieser Vorveröffentlichung wird eine Antennenanordnung für Kraftfahrzeuge beschrieben, welche ein Chassis aufweist, ober- halb dessen eine Leiterplatine angeordnet ist, und zwar zur Aufnahme von Schaltungsbauelementen. Vertikal zu der im Wesentlichen horizontal ausgerichteten Leitungsplatine sind ein oder mehrere vertikal vorstehende und zumindest zum Teil flächige Antennenelemente vorgesehen, und zwar zum Empfang unterschiedlicher Dienste oder für den Mobilfunkbereich in verschiedenen Frequenzen.A generic antenna arrangement has become known, for example, from DE 201 11 229 U 1. In this prior publication, an antenna arrangement for motor vehicles is described, which has a chassis, above which a printed circuit board is arranged, specifically for receiving circuit components. One or more vertically projecting and at least partially flat antenna elements are provided vertically to the essentially horizontally oriented line board, namely for receiving different services or for the mobile radio range in different frequencies.
Die gesamte Antennenanordnung ist durch eine Haube abgedeckt, die finnenähnliche Form aufweisen kann. Derartige Antennen werden üblicherweise auf dem Kraftfahrzeug-Karosserieblech angebracht, beispielsweise am Übergang des Kraftfahrzeug-Daches zum Heckfenster. Eine Mehr-Frequenz-Antennenanordnung insbesondere für Kraftfahrzeuge mit einer entsprechenden Haube ist aus der EP 0 862 239 AI bekannt geworden . In dem haubenf örmigen Gehäuse sind beispielsweise zwei vertikal ausgerichtete und quer zur Vertikalebene seitlich versetzt liegende Leiterplatinen zur Aufnahme der elektronischen Bauelemente vorgesehen . Am oberen Ende des Gehäuses , also am höchsten Punkt der Haube, ist ein Anschlussadapter vorgesehen, um dort eine peitschenf örmige Antenne befestigen zu können .The entire antenna arrangement is covered by a hood, which can have a fin-like shape. Such antennas are usually attached to the motor vehicle body sheet, for example at the transition from the motor vehicle roof to the rear window. A multi-frequency antenna arrangement, in particular for motor vehicles with a corresponding hood, has become known from EP 0 862 239 AI. In the hood-shaped housing, for example, two vertically aligned printed circuit boards which are laterally offset transversely to the vertical plane are provided for receiving the electronic components. At the upper end of the housing, i.e. at the highest point of the hood, a connection adapter is provided in order to attach a whip-shaped antenna there.
Aus der DE 694 19 080 C2 ist ebenfalls eine vorzugweise für Autos verwendbare Antenne bekannt geworden . Auch diese weist ein haubenf örmiges Gehäuse auf , an derem höchsten Erhebungspunkt eine Anschlussstelle für eine peitschenf ör- mige Antenne vorgesehen ist . Innerhalb des Antennengehäuses können eine oder mehrere vertikal oder horizontal ausgerichtete Leiterplatinenelemente angeordnet sein . Diese sind in einer Aus führungs form ebenfalls parallel zueinander und quer zur Ebene der Leiterplatine nebenein- ander sitzend angeordnet , und zwar in einer Ausrichtung quer zur Fahrzeuglängsachse . Ebenso können sie aber auch mit Seitenversatz parallel zueinander angeordnet sein, und zwar in einer Ausrichtung längs zur Fahrzeugachse .From DE 694 19 080 C2 an antenna that can preferably be used for cars has also become known. This also has a hood-shaped housing, at the highest point of elevation of which a connection point for a whip-shaped antenna is provided. One or more vertically or horizontally oriented printed circuit board elements can be arranged within the antenna housing. In one embodiment, these are also arranged parallel to one another and transversely to the plane of the printed circuit board, next to one another, in an orientation transverse to the longitudinal axis of the vehicle. Likewise, however, they can also be arranged parallel to one another with a lateral offset, specifically in an alignment along the vehicle axis.
Darüber hinaus sind auch Antennenanordnungen bekannt geworden, bei welchen auf einem mehr oder weniger waagerechten Chassis aufbauend zunächst die erwähnte Leiterplatine mit den schaltungselektronischen Bauelementen, Filterbaukreisen etc . vorgesehen ist , und die Antennenelemente wiederum senkrecht dazu in Vertikalrichtung positioniert sind . Diese können beispielsweise nicht nur aus metallisch leitenden selbsttragenden Strahlereinrichtungen bestehen, sondern beispielsweise ebenfalls wieder aus einem Leiter- platinenelement, d.h. allgemein aus einem dielektrischen Material, auf welchem metallisierte Flächen zur Bildung der Strahler ausgebildet sind.In addition, antenna arrangements have also become known in which, based on a more or less horizontal chassis, the aforementioned printed circuit board with the electronic circuit components, filter assemblies, etc. is provided, and the antenna elements are in turn positioned perpendicular to it in the vertical direction. For example, these can not only consist of metallically conductive self-supporting emitter devices, but also again, for example, of a conductor Circuit board element, ie generally made of a dielectric material, on which metallized surfaces are formed to form the radiators.
Soll nur in einem Frequenzbandbereich empfangen werden, so genügt ein Strahlerelement. Sollen mehrere Dienste oder ein Dienst mehrmals realisiert werden, oder soll beispielsweise eine Kommunikation in verschiedenen Frequenzbänden im Mobilfunkbereich ermöglicht werden, so sind naturgemäß dann mehrere versetzt zueinander liegende Strahler oder flächige Antennenelemente vorgesehen.If only one frequency band is to be received, one radiator element is sufficient. If several services or one service are to be implemented several times, or if, for example, communication is to be made possible in different frequency bands in the mobile radio range, then a plurality of radiators or flat antenna elements which are offset from one another are naturally provided.
Aufgabe der vorliegenden Erfindung ist es, ausgehend von diesem Stand der Technik eine weitere verbesserte Anten- nenanordnung zu schaffen, die grundsätzlich gute Antenneneigenschaften bei insgesamt verringerten Herstellungs-und Materialkosten aufweist.It is the object of the present invention, based on this prior art, to provide a further improved antenna arrangement which basically has good antenna properties with overall reduced manufacturing and material costs.
Die Aufgabe wird erfindungsgemäß entsprechend den in An- spruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved according to the invention in accordance with the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.
Es hat sich nunmehr in überraschender Weise gezeigt, dass auf die horizontale Ausbildung einer separaten Leiterplatine mit der für die Antenne notwendigen Anpass-Schal- tung verzichtet werden kann. Erfindungsgemäß wird nämlich eine oder mehrere vorzugsweise nebeneinander in einer gemeinsamen Ebene sitzende vertikal ausgerichtete Leiter- platinen verwendet, die angrenzend zu dem zumindest einen Antennenelement vorgesehen ist. Auf dieser vertikal ausgerichteten Leiterplatine sind z.B. die entsprechenden Bauelemente für eine eventuell vorgesehene Hochfrequenz- Schaltung mit untergebracht.It has now surprisingly been found that the horizontal formation of a separate printed circuit board with the matching circuit required for the antenna can be dispensed with. According to the invention, one or more vertically aligned printed circuit boards are preferably used, which are preferably located next to one another in a common plane and are provided adjacent to the at least one antenna element. The corresponding components for a possibly provided high-frequency Circuit housed with.
Erfindungsgemäß wird durch die Verwendung einer vertikal ausgerichteten Leiterplatine nochmals eine deutliche Ver- einfachung des Gesamtaufbaus einer entsprechenden Antennenanordnung ermöglicht. Überraschend ist bei dieser Ausbildung, dass durch die vertikal ausgerichtete und seitlich an dem Antennenelement ansetzende Leiterplatine das Antennen-Diagramm nicht in an sich zu erwartender Weise nachteilig beeinflusst wird.According to the invention, the use of a vertically aligned printed circuit board once again makes it possible to significantly simplify the overall structure of a corresponding antenna arrangement. It is surprising in this embodiment that the antenna diagram is not adversely affected in the manner to be expected by the vertically aligned printed circuit board attached to the side of the antenna element.
Die erfindungsgemäße Lösung zeichnet sich unter anderem auch dadurch aus, dass abweichend zum Stand der Technik die zumindest eine Antennen-Strahleranordnung nicht ober- halb der Leiterplatinen, sondern seitlich neben dieser zumindest einen Leiterplatine vorgesehen ist. Dadurch wird ein ungünstige Beeinflussung der Strahlungscharakteristik vermieden. Dies ist vor allem deshalb auch überraschend und nicht naheliegend, da eine derartige möglichst breit- bandige Antenne für den Mobilfunkbereich auf Wellenlängen im Bereich von rund 15 cm bis 30 cm ausgelegt ist, und somit die Größe der stehend angeordneten Leiterplatine in diesen Wellenlängen relevanten Bereich liegt.The solution according to the invention is also distinguished, inter alia, by the fact that, in contrast to the prior art, the at least one antenna radiator arrangement is not provided above the printed circuit boards, but at the side next to this at least one printed circuit board. This avoids an unfavorable influence on the radiation characteristics. This is particularly surprising and not obvious, since such a broadband antenna for the mobile radio range is designed for wavelengths in the range of around 15 cm to 30 cm, and the size of the upright printed circuit board is therefore in the relevant range for these wavelengths ,
Bevorzugt ist es ferner möglich, lediglich eine einzige Leiterplatine vorzusehen, auf der dann nicht nur die eventuell vorgesehene Hochfrequenz-Schaltung untergebracht ist, sondern auf anderen Abschnittsbereichen dann beispielsweise auch flächige leitende Abschnitte ausgebildet sein können, die das betreffende Antennenelement bilden. Dabei sind unterschiedlichste geometrische Formen zur Bildung des Antennenelements möglich, beispielsweise auch peitschenähnliche Ausbildungsformen, die einen vertikal verlaufenden, flächigen Antennenabschnitt aufweisen, der oben in einen beispielsweise nachlaufenden Antennenabschnitt übergeht.It is preferably also possible to provide only a single printed circuit board, on which not only the high-frequency circuit that may be provided is then accommodated, but also, for example, planar conductive sections that form the antenna element in question can also be formed on other section areas. A wide variety of geometric shapes are possible for forming the antenna element, for example also whip-like shapes that are vertical have extending, flat antenna section, which merges into a trailing antenna section, for example.
Soll beispielsweise für ein zweites Frequenzband für den Mobilfunkbereich oder für die Realisierung weiterer Dienste ein weiteres Antennenelement vorgesehen sein, so kann dieses ebenfalls bevorzugt als flächig ausgebildetes Antennenelement in einem zum ersten Antennenelement versetz- ten Bereich auf der Leiterplatine realisiert werden. Genauso kann aber auch ein weiteres Leiterplatinenelement verwendet werden, was in der gleichen Ebene zum ersten Leiterplatinenelement liegt oder beispielsweise mit Parallelversatz seitlich dazu, um hier das zumindest eine weitere Antennenelement unterzubringen.If, for example, a further antenna element is to be provided for a second frequency band for the mobile radio range or for the implementation of further services, this can also preferably be implemented as a flat antenna element in an area on the circuit board offset from the first antenna element. In the same way, however, a further printed circuit board element can also be used, which lies in the same plane as the first printed circuit board element or, for example, with a parallel offset to the side in order to accommodate the at least one further antenna element here.
Somit lassen sich letztlich bevorzugt auf einer einzigen gemeinsamen Leiterplatinenanordnung die Antennenelemente und die eventuell vorgesehene Hochfrequenz-Schaltung un- terbringen.In the end, the antenna elements and the possibly provided high-frequency circuit can thus preferably be accommodated on a single common printed circuit board arrangement.
Lediglich für den Einbau am Kraftfahrzeug sowie für die mechanische Verankerung der Leiterplatine und der darauf befindlichen Antennenelemente ist noch ein der mechani- sehen Halterung dienender Sockel notwendig.Only for the installation on the motor vehicle as well as for the mechanical anchoring of the printed circuit board and the antenna elements located thereon is a base required for the mechanical mounting necessary.

Mit anderen Worten ist auf dieser gemeinsamen Leiterplatine 15 in Kraftfahrzeugrichtung vorlaufend, also im gezeigten Ausführungsbeispiel in der Zeichnung auf der links liegenden vorlaufenden Seite 17 wieder das flächige Strahlerelement 9 mit den beiden flächigen Strahlerabschnitten 9', 9" und der Kombination bestehend aus Induktivität und Kapazität 13 vorgesehen, beispielsweise durch eine entsprechende auf der Leiter- platine 15 ausgebildeten Metallisierung.In the exemplary embodiment according to FIG. 3 it is shown that the entire arrangement is provided on a common printed circuit board 15. In other words, on this common circuit board 15 leading in the direction of the motor vehicle, that is to say in the exemplary embodiment shown in the drawing on the leading side 17 on the left, the planar radiator element 9 with the two planar radiator sections 9 ′, 9 ″ and the combination consisting of inductance and capacitance 13 is provided, for example by a corresponding metallization formed on the printed circuit board 15.
In einem z.B. rechteckförmig umgrenzten Raum 15' ist dann wiederum die eventuell vorgesehene Hochfrequenz-Schaltung mit den entsprechenden Bauteilen und Baukomponenten unter- gebracht.In a e.g. Rectangularly delimited space 15 'is then again accommodated with the high-frequency circuit that may be provided with the corresponding components and components.
Bei dem Ausführungsbeispiel gemäß Figur 3 ist ferner auf der gemeinsamen, vertikal ausgerichteten Leiterplatine 15 im nachlaufenden Bereich 18 der Leiterplatine 15 eine zweite Strahleranordnung 29 z.B. in Form einer metallisierten Fläche vorgesehen. Die eventuell vorgesehene Hochfrequenz-Schaltung für die beiden Strahleranordnungen 9, 29 im Leiterplatinenabschnitt 15' ist auf der gemeinsamen Leiterplatine 15 zwischen den beiden Strahleranord- nungen 9, 29 untergebracht.In the exemplary embodiment according to FIG. 3, a second radiator arrangement 29, for example on the common, vertically oriented printed circuit board 15 in the trailing region 18 of the printed circuit board 15, is e.g. provided in the form of a metallized surface. The possibly provided high-frequency circuit for the two radiator arrangements 9, 29 in the printed circuit board section 15 'is accommodated on the common printed circuit board 15 between the two radiator arrangements 9, 29.
Abweichend zu dem gezeigten Ausführungsbeispiel nach Figur 3 können natürlich die Strahleranordnungen 9 und 29 von der Leiterplatine 15 getrennt ausgebildet sein. Aber auch in diesem Ausführungsbeispiel würde die Leiterplatine 15 in Vertikalausrichtung bevorzugt unmittelbar seitlich zwischen den beiden Strahleranordnungen 9, 29 zu liegen kommen .In a departure from the exemplary embodiment shown in FIG. 3, the radiator arrangements 9 and 29 of FIG the printed circuit board 15 may be formed separately. But also in this exemplary embodiment, the printed circuit board 15 would preferably come to lie directly to the side between the two radiator arrangements 9, 29 in the vertical orientation.
Die gesamte Anordnung wird wie erwähnt durch den Sockel oder die sogenannte Basisplatte 7 mechanisch gehalten.As mentioned, the entire arrangement is held mechanically by the base or the so-called base plate 7.
Bei Bedarf können an der Leiterplatine 15 auch gewisse Abschnitte weggelassen oder ausgebrochen sein, wenn dort beispielsweise ein Antennenelement untergebracht werden soll, welches in Abweichung zum gezeigten Ausführungsbeispiel nicht vertikal ausgerichtet ist, beispielsweise im Fall einer GPS-Antenne.If necessary, certain sections of the printed circuit board 15 can also be omitted or broken out if, for example, an antenna element is to be accommodated there which, in deviation from the exemplary embodiment shown, is not oriented vertically, for example in the case of a GPS antenna.
In Ergänzung zur gezeigten und beschriebenen Figur 1 ist noch eine weitere Figur la dargestellt, wobei der wesentliche Unterschied bei Figur la gegenüber Figur 1 ist, dass es sich bei dem Ausführungsbeispiel gemäß Figur la um eine Aufdach-Montage handelt. Mit anderen Worten wird also die Sockel- oder Basisplatte 7 von oben her auf dem Karosserieblech 1, in der Regel auf dem Karosseriedach montiert, so dass die Sockel- oder Basisplatte 7 die Öffnung 3 über- deckt.In addition to FIG. 1 shown and described, a further FIG. 1 a is shown, the main difference in FIG. 1 a compared to FIG. 1 being that the exemplary embodiment according to FIG. 1 a is a roof installation. In other words, the base or base plate 7 is mounted from above on the body panel 1, usually on the body roof, so that the base or base plate 7 covers the opening 3.
Bei dem Ausführungsbeispiel gemäß Figur lb ist mit einer andersartig ausgebildeten Basis- oder Sockelplatte 7 gezeigt, dass die Antennenanordnung auch auf einer Scheibe, vorzugsweise auf einer Heckscheibe eines Kraftfahrzeuges bevorzugt am oberen Rand in der Nähe zum Übergang zum Karosseriedach montiert werden kann. In allen Fällen wird noch eine entsprechende, nicht näher dargestellte Schutz- haube aufgesetzt, die die gesamte gezeigte Antennenanordnung überdeckt und schützt. In the exemplary embodiment according to FIG. 1b, it is shown with a differently designed base or base plate 7 that the antenna arrangement can also be mounted on a window, preferably on a rear window of a motor vehicle, preferably at the upper edge in the vicinity of the transition to the body roof. In all cases, a corresponding protection not shown is attached hood that covers and protects the entire antenna arrangement shown.
