Description

Die vorliegende Erfindung betrifft eine Funkbaugruppe, insbesondere für ein Mobilfunk-Endgerät, welche eine leicht integrierbare Antenne umfasst.The present invention relates to a radio module, in particular for a mobile terminal, which is an easily integrable Antenna includes.

Eine Vielzahl unterschiedlicher Antennen wird derzeit in den Funkbaugruppen von Kommunikationsgeräten verwendet, die auf unterschiedliche Anwendungen hin optimiert sind. Da mit Kommunikationsgeräten ein Massenmarkt bedient wird, müssen diese Geräte und ihre Zubehörteile einfach und kostengünstig herstellbar und zusammenbaubar sein. Bei Antennen kommt zu diesen Anforderungen noch der Wunsch nach guten Sende- und Empfangseigenschaften hinzu. Die Erfüllung dieser drei Kriterien gleichzeitig steht in gewissem Widerspruch zur stetig fortschreitenden Miniaturisierung der Kommunikationsgeräte:A large number of different antennas is currently used in the Radio modules of communication devices used on different applications are optimized. Because with communication devices a mass market is served, these must Devices and their accessories can be manufactured easily and inexpensively and be assembled. Antennas come to these Requirements still the desire for good sending and receiving properties added. The fulfillment of these three criteria at the same time stands in contradiction to the steadily progressing Miniaturization of communication devices:

Normalerweise sind die Antenne und weitere Bauteile auf einer Leiterplatte angeordnet. Der Platz auf der Leiterplatte ist beschränkt, so dass sich Antenne und weitere Bauteile oft in unmittelbarer Nähe zueinander befinden. Durch diese benachbarten Bauelemente werden die Sende- und Empfangseigenschaften der Antenne negativ beeinflusst. Bisher wurde kein zufriedenstellender Kompromiss gefunden, die Antenne einfach und billig herzustellen und in die Funkbaugruppe zu integrieren, wobei gleichzeitig die Sende- und Empfangseigenschaften der Antenne von weiteren Bauelementen der Funkbaugruppe weitgehend unbeeinflusst sind und zudem die Anordnung der Bauelemente und Antenne nicht konträr zur Miniaturisierung verläuft.Usually the antenna and other components are in one Printed circuit board arranged. The space on the circuit board is limited, so that antenna and other components are often in are in close proximity to each other. Through this neighboring Components are the send and receive properties affects the antenna negatively. So far, nothing has been satisfactory Compromise found, the antenna simple and cheap to manufacture and integrate into the radio module, with the transmission and reception properties at the same time the antenna of other components of the radio module largely are unaffected and also the arrangement of the components and antenna is not contrary to miniaturization.

Aus dem Dokument DE 197 13 929 A1 ist eine als eine Sende-Empfangs-Einrichtung realisierte Funkbaugruppe bekannt, die eine Leiterplatte aufweist, auf der die Bauelemente der Funkbaugruppe angeordnet sind. Eine Antenne ist mit ihrem ersten Ende mit der Leiterplatte verbunden. Ihr zweites Ende ist räumlich von der Leiterplatte getrennt. Die Antenne weist für die Verbindung mit der Leiterplatte Verbindungselemente auf.Document DE 197 13 929 A1 describes one as a transceiver realized radio module known that has a circuit board on which the components of the radio module are arranged. An antenna is with its first End connected to the circuit board. Your second end is spatially separated from the circuit board. The antenna points for the connection to the circuit board connection elements.

Aus dem Dokument DE 198 10 749 A1 ist weiter eine Funkbaugruppe bekannt, die eine mit einer Leiterplatte verbundene Antenne aufweist.From document DE 198 10 749 A1 there is also a radio module known, the one connected to a circuit board Has antenna.

Aufgabe der vorliegenden Erfindung ist es, eine Funkbaugruppe mit einer Antenne anzugeben, die gute Sende- und Empfangseigenschaften besitzt und gleichzeitig leicht herstellbar und integrierbar ist.The object of the present invention is a radio module to indicate with an antenna, the good transmission and reception properties owns and easy to manufacture and can be integrated.

Diese Aufgabe wird erfindungsgemäß durch eine Funkbaugruppe mit den Merkmalen des Anspruchs 1 gelöst. Weiterbildung der Erfindung ergeben sich aus den abhängigen Ansprüchen.This object is achieved by a radio module solved with the features of claim 1. Further training in Invention result from the dependent claims.

Erfindungsgemäß umfasst die Funkbaugruppe eine Leiterplatte, auf welcher neben der Antenne noch weitere Bauelemente angeordnet sind. Die Antenne ist hierbei mit der Leiterplatte über zwei Bereiche verbunden. Zum einen ist ein erstes Ende der Antenne flächenhaft ausgebildet, welches beispielsweise als Lötfuß dient. Zum zweiten ist die Antenne mit der Leiterplatte über ein Verbindungselement verbunden, dessen Fußpunkt ebenfalls als Auflagefläche dient. Die Projektion des Schwerpunktes der Antenne auf die Leiterplatte befindet sich hierbei innerhalb des Flächenbereichs, welcher durch den Fußpunkt des Verbindungselementes sowie dem flächenhaft ausgebildeten ersten Ende der Antenne bestimmt ist.According to the invention, the radio module comprises a printed circuit board, on which other components are arranged in addition to the antenna are. The antenna is here with the circuit board connected over two areas. First, there is a first end of the antenna formed areal, which, for example serves as a soldering foot. Second is the antenna with the circuit board connected via a connecting element, the base of which also serves as a support surface. The projection of the focus the antenna is on the circuit board within the area that passes through the base the connecting element as well as the area-trained first end of the antenna is determined.

Vorteilhaft daran ist, dass die Antenne, wenn sie zunächst lose auf die Leiterplatte aufgesetzt wird, nicht kippt, was beispielsweise günstig für einen automatischen Bestückungsprozess ist. Der Ablauf eines derartigen Bestückungsprozess kann beispielsweise folgende Schritte umfassen: Die Antenne wird zunächst automatisch auf die Leiterplatte gesetzt. Im Bereich der Auflageflächen befindet sich Lötmaterial. Sind alle Bauelemente auf die Leiterplatte aufgebracht, wird diese in einen Lötofen geschleust, in dem durch eine entsprechende Temperatur das Lötmaterial aufgeschmolzen und so eine dauerhafte Verbindung hergestellt wird.The advantage of this is that the antenna, when it first is loosely placed on the circuit board, does not tip what for example, cheap for an automatic assembly process is. The sequence of such an assembly process can include the following steps, for example: The antenna is first automatically placed on the circuit board. in the There is soldering material in the area of the contact surfaces. are all components are applied to the circuit board, this is smuggled into a soldering furnace in which a corresponding Temperature melted the solder material and so a permanent Connection is established.

Eine Weiterbildung der Erfindung sieht vor, dass sich die Bauelemente auf derselben Seite der Leiterplatte wie der Fußpunkt der Antenne befinden. Dies ist herstellungstechnisch von Vorteil, da Bauteile und Antenne von derselben Seite her bestückt werden könnten.A further development of the invention provides that the Components on the same side of the PCB as the base the antenna. This is manufacturing technology an advantage because components and antenna are from the same side could be equipped.

Eine andere Weiterbildung der Erfindung besteht darin, dass sich das dem ersten Ende entgegengesetzte zweite Ende der Antenne außerhalb des Bereichs der Leiterplatte befindet. Dadurch hat dieses Antennenende oder dieser Bereich der Antenne einen gewissen Mindestabstand zu weiteren Bauteilen, welche die Sende- und Empfangseigenschaften der Antenne beeinflussen können oder auch durch die Antenne beeinflusst werden. Die Form und räumliche Ausrichtung dieses Antennenbereichs oder Ende der Antenne kann aber auch beispielsweise durch die Gehäuseform definiert werden.
Metallbauteile, zu denen eine Mindestdistanz erforderlich ist, befinden sich beispielsweise in der Hörkapsel eines Mobilfunk-Endgerätes.Another development of the invention is that the second end of the antenna opposite the first end is located outside the region of the printed circuit board. As a result, this antenna end or this area of the antenna is at a certain minimum distance from other components, which can influence the transmission and reception properties of the antenna or are also influenced by the antenna. The shape and spatial orientation of this antenna area or end of the antenna can also be defined, for example, by the shape of the housing.
Metal components for which a minimum distance is required are located, for example, in the earpiece of a mobile radio terminal.

Eine Ausführungsvariante der Erfindung besteht darin, dass die Antenne auf einer Seite der Leiterplatte mit dieser leitend verbunden ist, und durch eine fensterartige Ausnehmung der Leiterplatte auf die gegenüberliegende Seite hinüberreicht. Damit ist das dem ersten Ende entgegengesetzte zweite Ende der Antenne durch die Leiterplatte von weiteren Bauelementen abgeschirmt, wodurch sich eine Verbesserung der Sendeund Empfangseigenschaften ergibt. Ebenso sind auf diesem Wege die Bauelemente natürlich gegenüber der Antenne abgeschirmt.An embodiment variant of the invention is that the antenna on one side of the circuit board is conductive with this is connected, and by a window-like recess the circuit board on the opposite side. It is the second opposite of the first end End of the antenna through the circuit board of other components shielded, which improves transmission and Receiving properties results. Likewise are on this path the components are of course shielded from the antenna.

Eine Weiterbildung der Erfindung kann darin bestehen, dass die Antenne mittels eines gebogenen Blechs realisiert wird. A further development of the invention can consist in that the antenna is realized by means of a bent plate.

Die Biegung des Blechs kann hierbei kontinuierlich oder stufenartig erfolgen. Diese Umsetzung weist den Vorteil auf, dass Mindestabstände flexibel realisiert werden können.The bending of the sheet can be continuous or step-like respectively. This implementation has the advantage that minimum clearances can be implemented flexibly.

Eine andere Weiterbildung der Erfindung besteht darin, dass die Breite der Antenne nicht über die gesamte Länge der Antenne konstant ist. Insbesondere besteht eine vorteilhafte Weiterbildung darin, dass die Antenne stufenförmig ausgebildet ist. Eine erste Stufe kann hierbei als Lötfuß fungieren, eine zweite Stufe, welche eine verhältnismäßig große Fläche aufweist, kann als Ansaugfläche für einen automatischen Bestückungsprozess dienen. Weitere Stufen sind in ihrer Form und Flächengröße den räumlichen Gegebenheiten und natürlich auch den spezifizierten elektromagnetischen Eigenschaften der Antenne angepasst.Another development of the invention is that the width of the antenna is not the entire length of the antenna is constant. In particular, there is an advantageous one Further development in that the antenna has a step-shaped design is. A first stage can act as a solder foot, a second stage, which is a relatively large area can be used as a suction surface for an automatic assembly process serve. Further levels are in their form and area size the spatial conditions and of course also the specified electromagnetic properties of the Antenna adjusted.

Eine andere Weiterbildung der Erfindung besteht darin, dass das flächenhafte erste Ende der Antenne nach oben gebogene Laschen aufweist. Dies ist aus folgenden Gründen vorteilhaft für eine dauerhafte Verbindung zwischen Antenne und Leiterplatte: Bei ihrer Herstellung werden die Antennen zumeist aus einem rostfreien und bereits verzinnten Material ausgestanzt. Das Material für die Verzinnung wird später für die Herstellung des Lötkontaktes zwischen Antenne und Leiterplatte benötigt. Man verwendet bereits verzinntes Blech deswegen, das die Antenne, wenn sie in fertigem Zustand verzinnt würde, was beispielsweise durch eine Trommelgalvanisierung geschehen kann, beschädigt werden könnte. An den Rändern der Antenne wird jedoch das Verzinnmaterial durch das Ausstanzen entfernt. Für einen zufriedenstellenden Kontakt zwischen Antenne und Leiterplatte ist jedoch ein Lötkontakt auf dem gesamten Bereich des Lötfußes erforderlich, und nicht nur in dessen Mitte. Dies kann durch die oben beschriebenen Laschen erreicht werden, an deren Biegekante sich ausreichend Lötmaterial befindet. Another development of the invention is that the flat first end of the antenna is bent upwards Has tabs. This is advantageous for the following reasons For a permanent connection between antenna and circuit board: The antennas are mostly made during their manufacture punched out of a rustproof and already tinned material. The material for tinning will later be used for manufacturing of the solder contact between the antenna and the circuit board. You already use tinned sheet metal because of that the antenna if it were tinned in the finished state what for example by drum galvanizing can be damaged. On the edges of the antenna however, the tinning material is removed by punching out. For a satisfactory contact between the antenna and circuit board is however a solder contact on the whole Area of the solder foot required, and not only in its Center. This can be achieved using the tabs described above sufficient soldering material on the bending edge located.

Im folgenden wird die Erfindung und ihre Weiterbildungen anhand von in Figuren gezeigten Ausführungsbeispielen erklärt.In the following, the invention and its developments are based on explained by embodiments shown in figures.

Figur 1 zeigt die Funkbaugruppe, welche die Antenne 1, die Leiterplatte 10 und weitere Bauelemente 12, beispielsweise ein HF- oder DECT-Modul, umfasst. Ebenso ist ein Teil der Hörkapsel 14 sichtbar. Die Antenne umfasst einen Lötfuß 3, an dem die Antenne auf die Leiterplatte gelötet werden kann. Die Antenne 1 entfernt sich stufenförmig von der Leiterplatte 10. Durch dieses stufenförmige Entfernen der Antenne von der Leiterplatte werden zwei Flächen ausgebildet, die im Wesentlichen parallel zu der Leiterplatte verlaufen. Hierbei weist eine erste Antennenfläche 5 eine größere Breite auf als eine zweite Antennenfläche 7. Zwischen Antenne 1 und Leiterplatte 10 befindet sich ein Verbindungselement 9.Figure 1 shows the radio module, the antenna 1, the Printed circuit board 10 and other components 12, for example an HF or DECT module. Also part of the Earpiece 14 visible. The antenna includes a solder foot 3 which the antenna can be soldered to the circuit board. The Antenna 1 moves away from the printed circuit board 10 in steps. This step-like removal of the antenna from the circuit board two areas are formed, which are essentially run parallel to the circuit board. Here points a first antenna area 5 has a greater width than one second antenna surface 7. Between antenna 1 and circuit board 10 there is a connecting element 9.

Vorteilig an dieser beispielhaften Ausführung ist folgendes:The following is an advantage of this exemplary embodiment:

Zum Aufsetzen der Antenne 1 auf die Leiterplatte 10 wird die Antenne 1 zunächst an der ersten Antennenfläche 5 mittels beispielsweise einer Pipette angesaugt. Nun kann die Antenne zur gewünschten Stelle auf der Leiterplatte 10 bewegt werden. Nach dem Aufsetzen der Antenne 1 auf die Leiterplatte 10 kippt die Antenne nicht, da die Projektion ihres Schwerpunktes 6 auf die Leiterplatte 10 innerhalb des Abstandes liegt, der durch das Verbindungselement 9 und die Begrenzungen des Lötfußes 3 bestimmt wird. Aufgrund der Begrenzungen des inneren und äußeren Lötfußes werden zwei Flächen definiert, hier wird auf die größere der beiden Bezug genommen. Das Verbindungselement 9 kann auch zur Einspeisung des elektromagnetischen Signals dienen.To place the antenna 1 on the circuit board 10, the Antenna 1 first on the first antenna surface 5 for example, sucked in a pipette. Now the antenna can be moved to the desired location on the circuit board 10. After placing the antenna 1 on the printed circuit board 10 does not tilt the antenna because the projection of its center of gravity 6 lies on the printed circuit board 10 within the distance, the by the connecting element 9 and the limits of Soldering foot 3 is determined. Because of the limitations of the interior and outer solder foot two areas are defined, here reference is made to the larger of the two. The connecting element 9 can also be used to feed the electromagnetic Serve signal.

Die Antenne wird also im Bereich des Lötfußes 3 und des Verbindungselements 9 auf die verzinnte Leiterplatte 10, auf welcher das Lot an den erforderlichen Stellen aufgebracht ist, angelötet. Die Laschen 4 am Lötfuß 3 erfüllen folgende Funktion: Bei ihrer Herstellung wird die Antenne 1 aus einem nicht korrodierenden, ebenfalls bereits verzinnten Blech herausgestanzt. Da das Lot beim Aufschmelzen nur zwischen verzinnten Bereichen fließt, bildet sich im Fall der hochgeklappten Lasche 4 eine für eine stabile Verbindung günstigere Verteilung des Lots aus.The antenna is in the area of the solder foot 3 and the connecting element 9 on the tinned circuit board 10 which applied the solder in the required places is soldered on. The tabs 4 on the soldering foot 3 fulfill the following Function: During its manufacture, antenna 1 is made from one punched out non-corrosive, also already tinned sheet. As the solder only melts between tinned Areas flows, forms in the case of the folded up Tab 4 a cheaper for a stable connection Distribution of the lot.

Um die Sende- und Empfangseigenschaften der Antenne 1 möglichst wenig zu beeinflussen, ist ein Mindestabstand zu manchen Bauelementen erforderlich. So wird beispielsweise durch die stufenförmige Ausführung der Antenne 1 der Abstand zur Hörkapsel 14 vergrößert.To the transmission and reception properties of the antenna 1 as possible To influence little is a minimum distance to some Components required. For example, by the stepped design of the antenna 1 the distance to Earpiece 14 enlarged.

Die Lage dieser Hörkapsel 14 ist in einer Ausschnittsvergrößerung von Figur 1 in Figur 2 sichtbar gemacht. Die Hörkapsel 14 enthält auch metallische Elemente 15.The position of this earpiece 14 is enlarged of Figure 1 made visible in Figure 2. The earpiece 14 also contains metallic elements 15.

Figuren 3a, b zeigen eine beispielhafte Ausführung der Erfindung, bei der die Antenne 1 durch eine fensterartige Ausnehmung 11 in der Leiterplatte 10 ragt. Die Antenne 1 kann von derselben Seite her aufgesetzt werden wie die übrigen Bauelemente 12. Dies wirkt sich vorteilhaft bei einem automatischen Bestückungsvorgang aus. Durch die Leiterplatte 10 ist die Antenne 1 weitgehend von den weiteren Bauelementen 12 abgeschirmt. Deshalb werden die Sende- und Empfangseigenschaften der Antenne 1 durch die weiteren Bauelemente 12 nicht wesentlich beeinflusst. FIGS. 3a, b show an exemplary embodiment of the invention, in which the antenna 1 through a window-like recess 11 protrudes in the circuit board 10. The antenna 1 can of are placed on the same side as the other components 12. This has an advantageous effect on an automatic Assembly process. Through the circuit board 10 is the antenna 1 largely shielded from the other components 12. That is why the send and receive properties the antenna 1 by the other components 12 is not essential affected.

Die Antenne 1 ist in die Ausnehmung 11 eingesetzt und mit der Leiterplatte 10 über das Verbindungselement 9 und den Lötfuß der Antenne 3 verbunden. Antenne 1 und Verbindungselement 9 sind hierbei an einem Verbindungspunkt 8 miteinander verbunden, beispielsweise indem sie miteinander vernietet werden.Figure 3b shows a view of the circuit board 10 from the component side ago. There are a large number on the printed circuit board 10 arranged by components.
