Mobiltelefon mit MehrbandantenneMobile phone with multi-band antenna
Die vorliegende Erfindung betrifft ein Mobilfunkgerät mit einer Mehrbandantenne, die eine mäanderförmige Leiterstruktur und eine Kontaktfeder zur Kontaktierung der Leiterstruktur mit einer Sender/Empfangselektronik aufweist.The present invention relates to a mobile radio device with a multi-band antenna, which has a meandering conductor structure and a contact spring for contacting the conductor structure with a transmitter / receiver electronics.
Ein derartiges Mobilfunkgerät kann beispielsweise als Mobiltelefon bzw. sog. Handy realisiert sein. Die Abmessungen für die Antenne eines derartigen Geräts, welche Antenne heutzutage in das Gehäuse weit verbreitet integriert ist, sind aus Designgründen eingeschränkt. Darüber hinaus soll dieses Mobilfunkgerät zunehmend nicht nur in einem einzigen Netz, entsprechend einem einzigen Frequenzbereich, sondern auch in mehreren Netzen, entsprechend mehreren Frequenzbereichen betrieben werden können. Es wird deshalb eine (integrierte) Antenne benötigt, die in zwei oder mehr Frequenzbereichen nutzbar ist. Ferner besteht die Anforderung an das in Rede stehende Mobilfunkgerät, dass seine Leistungsfähigkeit und sein Design möglichst .kostengünstig realisiert werden können.Such a mobile radio device can be implemented, for example, as a cell phone or so-called cell phone. The dimensions for the antenna of such a device, which antenna is now widely integrated into the housing, are limited for design reasons. In addition, this mobile radio device should increasingly be able to be operated not only in a single network, corresponding to a single frequency range, but also in several networks, corresponding to several frequency ranges. An (integrated) antenna is therefore required that can be used in two or more frequency ranges. Furthermore, there is a requirement for the mobile radio device in question that its performance and design can be realized as cost-effectively as possible.
Die ins Gehäuse integrierte Mehrbandantenne bekannter Mobilfunkgeräte ist beispielsweise aus mehreren Teilantennen realisiert. Bei diesen Teilantennen handelt es sich entweder um zylindersymmetrische Helixdrahtgebilde oder um planare Antennen, die bevorzugt auf Schaltkarten realisiert sind. Da ihre Grundformen jedoch nicht der Gestalt des Gehäuses entsprechen, das typischerweise allgemein elliptischen Querschnitt aufweist, benötigen solche Antennen im Gehäuse relativ viel Platz. Aus diesem Grund kann der Anforderung an das Design des Mobilfunkgeräts bei geringen Abmessungen nicht oder nur unzulänglich entsprochen werden. Aus der WO 99/22420 ist bekannt, die Mehrbandantenne des in Rede stehenden Mobilfunkgeräts durch Aufbringen von Mäanderstrukturen auf flexiblem Leiterplattenmaterial zu realisieren. Eine derartige Mehrbandantenne besitzt dadurch große Flexibilität. Die Kosten für das flexible Grundmaterial und die notwendige Kontaktierung des flexiblen Leitermaterials führen jedoch dazu, dass die Kosten für diese Antenne dem Mehrfachen der Kosten der vorstehend genannten nichtflexiblen Antenne entspricht.The multi-band antenna of known mobile radio devices integrated in the housing is realized, for example, from several partial antennas. These partial antennas are either cylindrical helical wire structures or planar antennas, which are preferably implemented on circuit boards. However, since their basic shapes do not correspond to the shape of the housing, which typically has a generally elliptical cross section, such antennas require a relatively large amount of space in the housing. For this reason, the requirements for the design of the mobile radio device cannot be met or can only be met inadequately in the case of small dimensions. It is known from WO 99/22420 to implement the multi-band antenna of the mobile radio device in question by applying meandering structures to flexible printed circuit board material. Such a multi-band antenna has great flexibility. However, the costs for the flexible base material and the necessary contacting of the flexible conductor material mean that the cost for this antenna corresponds to a multiple of the cost of the above-mentioned non-flexible antenna.
Eine Aufgabe der vorliegenden Erfindung besteht darin, ein Mobilfunkgerät der eingangs genannten Art zu schaffen, dessen Mehrbandantenne kostengünstig herstellbar ist und Freiheit bei der Wahl des Designs des Mobilfunkgeräts gewährleistet.An object of the present invention is to provide a mobile radio device of the type mentioned at the beginning, the multi-band antenna of which can be produced inexpensively and which guarantees freedom in the choice of the design of the mobile radio device.
Gelöst wird diese Aufgabe durch die Merkmale des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the features of claim 1. Advantageous developments of the invention are specified in the subclaims.
Da die mäanderförmige Leiterstruktur und die Kontaktfeder der Antenne erfindungsgemäß als in Abwicklung einander nicht überlappendes einstückiges Teil gebildet sind, kann diese Antenne problemlos und kostengünstig durch einen einzigen Stanzvorgang gefertigt werden, an den sich ggf. lediglich noch ein Biegevorgang anschließt. Da das erfindungsgemäße einstückige Stanzbiegeteil in weiten Grenzen beliebig geformt werden kann, kann es problemlos an das gewünschte Design des Mobilfunkgerätes angepasst werden, ohne dass auf die Struktur der Antenne Rücksicht genommen werden muss .Since the meandering conductor structure and the contact spring of the antenna are formed according to the invention as a one-piece part that does not overlap in processing, this antenna can be manufactured easily and inexpensively by a single stamping process, which may be followed only by a bending process. Since the one-piece stamped and bent part according to the invention can be shaped as desired within wide limits, it can be easily adapted to the desired design of the mobile radio device without having to take into account the structure of the antenna.
Ein weiterer Vorteil der erfindungsgemäßen Antenne besteht darin, dass sie mit hoher Fertigungsgeschwindigkeit und deshalb mit geringen Herstellungskosten hergestellt werden kann, weil auf die Standard-Stanz- und Biegetechnik rückgegriffen werden kann. Da die Mehrbandantenne als einteiliges Stanzbiegeteil ausgebildet ist, erübrigt sich eine separate Herstellung und Bereitstellung der Antennenfeder.Another advantage of the antenna according to the invention is that it can be manufactured at high production speed and therefore at low production costs, because the standard stamping and bending technology can be used. Since the multi-band antenna is designed as a one-piece stamped and bent part, there is no need for separate manufacture and provision the antenna spring.
Bevorzugt sind die mindestens zwei Mäanderstrukturen der als einstückiges Stanz- Biegeteil gebildeten Mehrbandantenne parallel geschaltet nebeneinander so nahe angeordnet, dass eine deutliche Verkopplung erzielt wird, so dass das Gesamtvolumen der Mehrbandantenne minimal ist. Die verteilten Teilinduktivitäten und Kapazitäten der Mäander werden dabei optimal genutzt, so dass die Antenne in mehreren Frequenzbändern zuverlässig betrieben werden kann. Durch Optimierung ist es möglich, die Mehrbandantenne beispielsweise in Nähe ihrer ersten Resonanzfrequenz für eines der Zielfrequenzbänder, beispielsweise GSM, einzusetzen, während sie nahe ihrer zweiten Resonanzfrequenz so breitbandig arbeitet, dass damit ein Einsatz bei zwei weiteren Frequenzbändern, beispielsweise PCN und PCS möglich ist.The at least two meandering structures of the multi-band antenna formed as a one-piece stamped and bent part are preferably arranged in parallel, side by side, so close that a clear coupling is achieved, so that the total volume of the multi-band antenna is minimal. The distributed partial inductances and capacities of the meanders are used optimally, so that the antenna can be operated reliably in several frequency bands. Optimization makes it possible to use the multi-band antenna, for example, in the vicinity of its first resonance frequency for one of the target frequency bands, for example GSM, while it is working so broadband near its second resonance frequency that use with two further frequency bands, for example PCN and PCS, is possible.
Ein weiterer Vorteil der einstückig als Stanzbiegeteil gebildeten Mehrbandantenne besteht darin, dass eine Nennimpedanz von 50 Ohm problemlos realisierbar ist, so dass diese Antenne ohne zusätzliches Anpassnetzwerk, das beim Stand der Technik erforderlich ist, betrieben werden kann. Dies gewährleistet, dass die erfindungsgemäß gebildete Antenne ohne die Verluste betrieben werden kann, die beim Stand der Technik durch Anpassungselemente unvermeidlich sind.Another advantage of the multi-band antenna, which is formed in one piece as a stamped and bent part, is that a nominal impedance of 50 ohms can be implemented without any problems, so that this antenna can be operated without an additional matching network, which is required in the prior art. This ensures that the antenna formed according to the invention can be operated without the losses which are unavoidable in the prior art due to adaptation elements.
Nachfolgend wird die Erfindung anhand der Zeichnungen beispielhaft näher erläutert; in dieser zeigen:The invention is explained in more detail below using the drawings as an example; in this show:

In Fig. 1 ist eine Mehrbandantenne allgemein mit der Bezugsziffer 10 bezeichnet. Bei der Mehrbandantenne 10 handelt es sich um ein einstückiges Stanz-Biegeteil, umfassend eine mäanderförmige Leiterstruktur mit einer ersten Mäander 11 und einer zweiten Mäander 12 und eine Kontaktfeder 13. Die beiden Mäander 11, 12 und die Kontaktfeder 13 sind relativ zueinander so angeordnet, dass sie sich in Abwicklung (in abgewickelter Gestalt) nicht überlappen. Die erste Mäander 11 ist ebenso wie die zweite Mäander 12 in Abwicklung planar gebildet und diese beiden Mäander liegen abgewickelt in zwei seitlich versetzten Ebenen und sind über einen Verbindungssteg 14 miteinander verbunden, der quer zu den Mäanderebenen verläuft. Die Kontaktfeder 13 ist im Bereich des Verbindungsstegs 14 angeordnet und stellt eine Verlängerung dieses Stegs dar.In Fig. 1, a multi-band antenna is generally designated by the reference number 10. The multi-band antenna 10 is a one-piece stamped and bent part, comprising a meandering conductor structure with a first meander 11 and a second meander 12 and a contact spring 13. The two meanders 11, 12 and the contact spring 13 are arranged relative to one another such that they do not overlap in processing (in developed form). The first meander 11, like the second meander 12, is planar in development and these two meanders are developed in two laterally offset planes and are connected to one another via a connecting web 14 which runs transversely to the meander planes. The contact spring 13 is arranged in the region of the connecting web 14 and represents an extension of this web.
Die erste Mäander 11 umfasst ausgehend vom Verbindungssteg 14 einen ersten Mäanderteil 15 mit zwei zueinander parallel verlaufenden Arme 16 und 17. An den ersten Mäanderteil 15 schließt sich ein zweiter Mäanderteil 18 an, der zwei parallel zueinander sowie parallel zu den Armen 16, 17 des ersten Mäanderteils 15 verlaufene Arme 19 und 20 umfasst. Der zweite Mäanderteil 18 ist über einen Quersteg 21 mit dem ersten Mäanderteil 17 verbunden. An den zweiten Mäanderteil schließt sich verbunden über einen Quersteg 22 ein dritter Mäanderteil 23 an, der zwei zueinander sowie zu den vorausgenannten Armen 16, 17 und 19, 20 parallele Arme 24, 25 umfasst. An einen dritten Mäanderteil 23 schließt sich ein vierter Mäanderteil 26 an, der mit dem vorausgehenden Mäanderteil 23 über einen Quersteg 27 verbunden ist und zwei Stege 28 und 29 umfasst, die zueinander sowie zu den vorausgehend genannten Armen parallel verlaufen. Über einen Quersteg 30 verbunden schließt sich an den vierten Mäanderteil 26 ein fünfter Mäanderteil 31 an, der wie die vorausgehenden Mäanderteile zwei Arme 32 und 33 in paralleler Ausrichtung umfasst. Der fünfte Mäanderteil 31 läuft in einen in Mäanderrichtung sich erstreckenden und um 90° einwärts gebogenen Abschlusssteg 34 aus.Starting from the connecting web 14, the first meander part 11 comprises a first meander part 15 with two arms 16 and 17 running parallel to one another Meander part 15 includes extending arms 19 and 20. The second meandering part 18 is connected to the first meandering part 17 via a crosspiece 21. Connected to the second meandering part is a third meandering part 23, connected via a crosspiece 22, which comprises two arms 24, 25 parallel to one another and to the aforementioned arms 16, 17 and 19, 20. A third meandering part 23 is adjoined by a fourth meandering part 26, which is connected to the preceding meandering part 23 via a transverse web 27 and comprises two webs 28 and 29 which run parallel to one another and to the previously mentioned arms. A fifth meandering part 31 connects to the fourth meandering part 26 via a crosspiece 30, which, like the preceding meandering parts, comprises two arms 32 and 33 in parallel alignment. The fifth meandering part 31 terminates in an end web 34 which extends in the meandering direction and is bent through 90 °.
Der jeweils gegenseitige Abstand der fünf Mäanderteile 15, 18, 23, 26 und 31 ist ebenso unterschiedlich gewählt wie der Relativabstand ihrer Arme 16, 17, 19, 20, 24, 25, 28, 29 und 32, 33. Diese Abstände und ihre Abfolge sind zugunsten des durch die Antenne abzudeckenden Frequenzbereichs optimiert.The mutual distance between the five meandering parts 15, 18, 23, 26 and 31 is chosen to be as different as the relative distance between their arms 16, 17, 19, 20, 24, 25, 28, 29 and 32, 33. These distances and their sequence are optimized in favor of the frequency range to be covered by the antenna.
Der zweite Mäander 12 ist weniger komplex aufgebaut als die erste Mäander 11 und umfasst einen einzigen Mäanderteil 35, der mit Abstand über dem Abschlusssteg 34 der ersten Mäanderteil 11 zu liegen kommt und zueinander sowie zu den Armen der ersten Mäander 11 parallel verlaufende Arme 36, 37 aufweist. Der Mäanderteil 35 ist durch ihren unteren Arm 36 über einen weiteren, langen Verbindungssteg 38 mit der Kontaktfeder 13 und dem Verbindungssteg 14 verbunden.The second meander 12 is of less complex construction than the first meander 11 and comprises a single meander part 35 which comes to lie at a distance above the end web 34 of the first meander part 11 and arms 36, 37 running parallel to one another and to the arms of the first meander 11 having. The meander part 35 is connected by its lower arm 36 via a further, long connecting web 38 to the contact spring 13 and the connecting web 14.
Durch die mäanderförmige Leiterstruktur 11, 12 der Mehrbandantenne 10 werden insgesamt drei Frequenzbereich festgelegt. Der diesbezügliche Reflexionsfaktor der Mehrbandantenne 10 ist in Fig. 3 mit durchgezogener Linie gezeigt und allgemein mit der Bezugsziffer 38 bezeichnet. Strichliert dargestellt und mit den Bezugsziffern 39,40 und 41 bezeichnet sind die drei Frequenzbereiche bzw. -bänder der Mehrbandantenne 10 entsprechend dem EGSM-Band, dem PCN-Band und dem PCS-Band.A total of three frequency ranges are defined by the meandering conductor structure 11, 12 of the multi-band antenna 10. The relevant reflection factor of the multi-band antenna 10 is shown in FIG. 3 with a solid line and is generally designated by the reference number 38. The three frequency ranges or bands of the multi-band antenna 10 corresponding to the EGSM band, the PCN band and the PCS band are shown in dashed lines and designated by the reference numbers 39, 40 and 41.
In Fig. 2 ist eine alternative Ausführungsform der Mehrbandantenne 10 von Fig. 1 gezeigt. Die in Fig. 2 gezeigte Mehrbandantenne 10' hat im wesentlichen den gleichen Grundaufbau wie die Mehrbandantenne 10 von Fig. 1, jedoch mit dem Unterschied, dass die Mäander in Abwicklung nicht in Ebenen, sondern auf gekrümmten Flächen zu liegen kommen und mit dem Unterschied, dass die erste Mäander 11' nicht fünf, sondern lediglich drei Mäanderteile umfasst. Die zweite Mäander 12' hingegen ist entsprechend der ersten Mäander 11 konfiguriert. Gleiche Elemente der Antenne 10' sind mit denselben Bezugsziffern bezeichnet wie bei der Antenne 10, weshalb sich einen nähere Erläuterung dieser Elemente erübrigt. Ein weiterer Unterschied der Antenne 10' gegenüber der Antenne 10 ist, dass die Abstände ihrer Mäanderteile sowie die Abstände der Arme der Mäanderteile unterschiedlich sind, so dass sich für die Antenne 10' ein anderer Reflexionsfaktor ergibt als für die Antenne 10.FIG. 2 shows an alternative embodiment of the multi-band antenna 10 from FIG. 1. The multi-band antenna 10 'shown in FIG. 2 has essentially the same basic structure as the multi-band antenna 10 from FIG. 1, but with the difference that the meanders do not lie in planes but on curved surfaces and with the difference that that the first Meander 11 'does not include five, but only three meander parts. The second meander 12 ', however, is configured according to the first meander 11. The same elements of the antenna 10 'are designated with the same reference numerals as for the antenna 10, which is why a detailed explanation of these elements is unnecessary. Another difference between the antenna 10 'and the antenna 10 is that the distances between its meandering parts and the distances between the arms of the meandering parts are different, so that a different reflection factor results for the antenna 10' than for the antenna 10.
Die Erfindung ist nicht auf die vorstehend erläuterten zwei speziellen Ausführungsformen einer Mehrbandantenne beschränl(t. Vielmehr kann die Erfindung in beliebigen Mäanderstrukturen verkörpert sein, einschließlich zickzackförmiger Strukturen, solange diese Strukturen in Abwicklung als nicht überlappendes einstückiges Stanzbiegeteil realisierbar sind.
