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

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 U1 bekannt geworden. In dieser Vorveröffentlichung wird eine Antennenanordnung für Kraftfahrzeuge beschrieben, welche ein Chassis aufweist, oberhalb 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 is for example from DE 201 11 229 U1 known. In this prior publication, an antenna assembly for motor vehicles is described, which has a chassis, above which a printed circuit board is arranged, for receiving circuit components. Vertically to the substantially horizontally oriented line board, one or more vertically projecting and at least partially planar antenna elements are provided, specifically for receiving different services or for the mobile radio area 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.The entire antenna arrangement is covered by a hood, which may have a fin-like shape. Such antennas are usually mounted on the motor vehicle body panel, for example, at the transition of the motor vehicle roof to the rear window.

Eine Mehr-Frequenz-Antennenanordnung insbesondere für Kraftfahrzeuge mit einer entsprechenden Haube ist aus der EP 0 862 239 A1 bekannt geworden. In dem haubenförmigen 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 peitschenförmige Antenne befestigen zu können.A multi-frequency antenna arrangement, in particular for motor vehicles with a corresponding hood is known from the EP 0 862 239 A1 known. In the hood-shaped housing, for example, two vertically aligned and laterally offset transversely to the vertical plane printed circuit boards for receiving the electronic components are provided. At the upper end of the housing, ie 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 haubenförmiges Gehäuse auf, an derem höchsten Erhebungspunkt eine Anschlussstelle für eine peitschenförmige Antenne vorgesehen ist. Innerhalb des Antennengehäuses können eine oder mehrere vertikal oder horizontal ausgerichtete Leiterplatinenelemente angeordnet sein. Diese sind in einer Ausführungsform ebenfalls parallel zueinander und quer zur Ebene der Leiterplatine nebeneinander 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 the DE 694 19 080 C2 has also become known, preferably for cars usable antenna. This also has a hood-shaped housing, at the highest point of elevation a connection point for a whip-shaped antenna is provided. Within the antenna housing, one or more vertically or horizontally oriented printed circuit board elements may be arranged. These are also arranged in an embodiment also parallel to each other and across the plane of the printed circuit board sitting side by side, in an orientation transverse to the vehicle longitudinal axis. Likewise, they can also be arranged with side offset parallel to each other, in an orientation 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 Leiterplatinenelement, d.h. allgemein aus einem dielektrischen Material, auf welchem metallisierte Flächen zur Bildung der Strahler ausgebildet sind.In addition, antenna arrangements have become known in which on a more or less horizontal chassis building initially mentioned printed circuit board with the circuit electronic components, filter assemblies, etc. is provided, and the antenna elements are in turn positioned perpendicular thereto in the vertical direction. These may, for example, not only consist of metallically conductive self-supporting radiator devices, but for example also again of a printed circuit board element, i. generally 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 Frequenzbändern im Mobilfunkbereich ermöglicht werden, so sind naturgemäß dann mehrere versetzt zueinander liegende Strahler oder flächige Antennenelemente vorgesehen.If you want to receive only in a frequency band range, a radiator element is sufficient. If several services or a service are to be implemented several times, or if, for example, a communication in different frequency bands in the mobile radio area is to be enabled, then naturally a plurality of mutually offset radiators or planar antenna elements are provided.

Eine gattungsbildende Antennenanordnung ist aus der US 5 181 044 A bekannt geworden. Es handelt sich um eine auf einem Fahrzeugdach montierbare Antenne. Diese Antenne umfasst als ein wesentliches strahlendes Element eine sogenannte "Top Load Plate" oder "disk". Darunter liegend ist zwischen einer Basis- oder Metallplatte und dem für die Antenne wesentlichen Strahlungselement eine Speise- und Anpassschaltung vorgesehen, die auch aus einer Leiterplatine bestehen kann. Dabei kann die Speise- und Anpassschaltung auch als kapazitives oder induktives Element ausgebildet sein.A generic antenna arrangement is known from US 5,181,044 A known. It is a mountable on a vehicle roof antenna. This antenna comprises, as an essential radiating element, a so-called "top load plate" or "disk". Underneath is provided between a base or metal plate and the radiation element essential for the antenna, a supply and matching circuit, which may also consist of a printed circuit board. In this case, the supply and matching circuit can also be designed as a capacitive or inductive element.

Aufgabe der vorliegenden Erfindung ist es, ausgehend von diesem Stand der Technik eine weitere verbesserte Antennenanordnung zu schaffen, die grundsätzlich gute Antenneneigenschaften bei insgesamt verringerten Herstellungs-und Materialkosten aufweist.The object of the present invention is to provide, starting from this prior art, 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 Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved according to the invention specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Erfindungsgemäß hat sich nunmehr gezeigt, dass die zumindest eine Strahleranordnung aus einer leitenden oder metallisierten Fläche aus einer vertikal ausgerichteten Leiterplatine bestehen kann. Anstelle der Leiterplatine kann auch ein anderes vertikal ausgerichtetes dielektrisches Trägermaterial Verwendung finden. Die Leiterplatine sowie die zumindest eine Strahleranordnung sind dabei parallel zueinander oder in einer gemeinsamen Ebene liegend angeordnet.According to the invention it has now been found that the at least one radiator arrangement can consist of a conductive or metallized surface of a vertically aligned printed circuit board. Instead of the printed circuit board, another vertically oriented dielectric substrate can be used. The printed circuit board and the at least one radiator arrangement are arranged lying parallel to each other or lying in a common plane.

Durch die Verwendung einer vertikal ausgerichteten Leiterplatine wird insgesamt ein einfacher Gesamtaufbau einer entsprechenden Antennenanordnung möglich. 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.By using a vertically oriented printed circuit board, overall a simple overall construction of a corresponding antenna arrangement becomes possible. It is surprising in this embodiment that the antenna diagram is not adversely affected by the vertically oriented and laterally applied to the antenna element circuit board in the expected manner.

Die erfindungsgemäße Lösung zeichnet sich unter anderem auch dadurch aus, dass abweichend zum Stand der Technik die zumindest eine Antennen-Strahleranordnung nicht oberhalb 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 breitbandige 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 diesem wellenlängenrelevanten Bereich liegt.The solution according to the invention is also characterized, inter alia, by the fact that, unlike the prior art, the at least one antenna radiator arrangement is not provided above the printed circuit boards, but laterally beside this at least one printed circuit board. As a result, an unfavorable influence on the radiation characteristic is avoided. This is especially surprising and not obvious, since such a broadband antenna as possible for the mobile sector to wavelengths in the range of about 15 cm to 30 cm is designed, and thus the size of the standing PCB arranged in this wavelength relevant Area is located.

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.Preferably, it is also possible to provide only a single printed circuit board, on which then not only the possibly provided high-frequency circuit is housed, but then on other sections areas, for example, planar conductive sections may be formed, which form the relevant antenna element. In this case, a wide variety of geometric shapes for forming the antenna element are possible, for example, whip-like forms of training, which have a vertically extending, planar antenna section which merges into an upper, for example, trailing antenna section.

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 versetzten 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, then this antenna element can likewise be realized as a planar antenna element in a region offset on the first antenna element on the printed circuit board. Equally, however, it is also possible to use a further printed circuit board element, which lies in the same plane to the first printed circuit board element or, for example, with a parallel offset laterally, 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 unterbringen.Thus, ultimately, the antenna elements and possibly provided high-frequency circuit can ultimately 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 mechanischen Halterung dienender Sockel notwendig.Only for the installation on the motor vehicle and for the mechanical anchoring of the printed circuit board and the antenna elements thereon is still a mechanical support serving socket necessary.

Bei dem Ausführungsbeispiel gemäß Figur 3 ist gezeigt, dass die gesamte Anordnung auf einer gemeinsamen Leiterplatine 15 vorgesehen ist. 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 Leiterplatine 15 ausgebildeten Metallisierung.In the 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 printed circuit board 15 in the direction of the motor vehicle leading, so in the embodiment shown in the drawing on the left leading side 17 again the planar radiator element 9 with the two area radiator sections 9 ', 9 "and the combination consisting of inductance and capacitance 13, for example, by a corresponding on the circuit board 15th trained metallization.

In einem z.B. rechteckförmig umgrenzten Raum 15' ist dann wiederum die eventuell vorgesehene Hochfrequenz-Schaltung mit den entsprechenden Bauteilen und Baukomponenten untergebracht.In a e.g. rectangular space 15 'is then in turn the possibly provided high-frequency circuit housed 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 Strahleranordnungen 9, 29 untergebracht.In the embodiment according to FIG. 3 Furthermore, a second radiator arrangement 29, for example in the form of a metallized surface, is provided on the common, vertically aligned printed circuit board 15 in the trailing region 18 of the printed circuit board 15. 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.Deviating from the exemplary embodiment shown FIG. 3 Of course, the radiator assemblies 9 and 29 may be formed separately from the printed circuit board 15. But even in this embodiment, the printed circuit board 15 in vertical alignment would preferably come to lie directly laterally between the two radiator assemblies 9, 29.

Die gesamte Anordnung wird wie erwähnt durch den Sockel oder die sogenannte Basisplatte 7 mechanisch gehalten.The entire assembly is mechanically held as mentioned 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 required, certain sections may also be omitted or broken off on the printed circuit board 15 if, for example, an antenna element is to be accommodated there, which is not vertically aligned in deviation from the exemplary embodiment shown, 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 derwesentliche 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 überdeckt.In addition to the shown and described FIG. 1 is still another figure la shown, with the essential difference in Figure la compared FIG. 1 is that it is an on-roof mounting in the embodiment according to FIG la. In other words, therefore, 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, the opening 3 covers.

Bei dem Ausführungsbeispiel gemäß Figur 1b ist mit einer andersartig ausgebildeten Basis- oder Sokkelplatte 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 Schutzhaube aufgesetzt, die die gesamte gezeigte Antennenanordnung überdeckt und schützt.In the embodiment according to FIG. 1b is shown with a differently shaped base or Sokkelplatte 7 that the antenna assembly can also be mounted on a disc, 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, not shown guard is placed, which covers and protects the entire antenna array shown.
