Description

Die vorliegende Erfindung betrifft eine Antenne für funkbetriebene Kommunikationsendgeräte, bei welche die eigentliche Antennenstruktur von einer auf einer Leiterplatte befindlichen eine beliebige Form aufweisende Leiterplatte gebildet wird.The present invention relates to an antenna for radio-operated Communication terminals, in which the actual Antenna structure of one on a printed circuit board printed circuit board having any shape becomes.

In Hinsicht auf die Entwicklung in der Mobilfunktechnologie werden Antennen benötigt, welche in der Lage sind mehrere Frequenzbänder gleichzeitig abzudecken. Außerdem verlangt der Markt nach immer kleineren und billigeren Mobilfunkgeräten. Deswegen sind Antennen gefordert, die einen geringen Platzbedarf haben, problemlos für eine Funktion in mehreren Frequenzbändern oder einem breitbandigen Frequenzbereich auslegbar und billig und reproduzierbar herstellbar sind.With regard to the development in cellular technology antennas are required, which are capable of several Cover frequency bands at the same time. In addition, the Market for ever smaller and cheaper mobile devices. This is why antennas are required that take up little space have, for a function in several frequency bands or a broadband frequency range and can be produced cheaply and reproducibly.

Die bisherigen Konzepte, wie z. B. die Helix-Drahtantennen oder die Mikrostreifenleitungsantennen haben alle den Nachteil, daß sie entweder einen zu hohen Platzbedarf haben oder die Abstimmbarkeit bei einer Multiband-Funktion nicht ohne weiteres möglich ist.The previous concepts, such as B. the helix wire antennas or the microstrip antennas all have the disadvantage that they either have too much space or the tunability with a multiband function is not without further is possible.

Diese Aufgabe wird für die eingangs genannte Antenne dadurch gelöst, daß eine mehrlagige Leiterplatte vorgesehen ist, wobei auf jeder Lage der mehrlagigen Leiterplatte eine unterschiedliche Antennenstruktur appliziert ist.This task is for the antenna mentioned in the introduction solved that a multi-layer circuit board is provided, wherein a different one on each layer of the multilayer printed circuit board Antenna structure is applied.

Die erfindungsgemäße Antenne ist leicht und billig herstellbar, erfordert einen geringen Platzbedarf und ist problemlos für eine Funktion in mehreren Frequenzbändern oder in einem breitbandigen Frequenzbereich auslegbar.The antenna according to the invention is easy and inexpensive to manufacture, requires little space and is easy for a function in several frequency bands or in one broadband frequency range can be designed.

Weitere zweckmäßige Ausgestaltungen der erfindungsgemäßen Antenne ergeben sich aus den Unteransprüchen sowie aus einer nachfolgenden Beschreibung von Ausführungsbeispielen anhand der Zeichnung.Further expedient configurations of the antenna according to the invention result from the subclaims and from a The following description of exemplary embodiments based on the drawing.

    • Die einzelnen Antennenstrukturen entstehen durch unterschiedlich ausgebildete Leiterbahnen in den verschiedenen Lagen der mehrlagigen Leiterplatte. Dabei können die Antennenstrukturen, die in den Figuren 1 bis 8 beispielhaft gezeigte Formen, aber auch darüber hinausgehende Formen, annehmen. Vorzugsweise hat die Leiterbahn die Form eines Mäanders, einer Schlangenlinie oder die Form eines Stabes. Die Leiterbahnen können sich auch wie in den Figuren 5 und 6 gezeigt ist, verzweigen und an unterschiedlichen Punkten B bis N1, welche in einer Ebene liegen, enden. Weiterhin ist es möglich, daß in einer Lage jeweils mehrere eine Antenne bildende Leiterbahn nebeneinander angeordnet sind.The individual antenna structures arise from different trained conductor tracks in the different locations of the multilayer printed circuit board. The antenna structures, the forms shown by way of example in FIGS. 1 to 8, but also take other forms. Preferably the track has the shape of a meander, a serpentine line or the shape of a rod. The conductor tracks can branch as shown in FIGS. 5 and 6 and at different points B to N1, which in one Level, end. It is also possible that in a Lay several conductors forming an antenna next to each other are arranged.

    In den Figuren 9A bis 10 ist eine vierlagige Antenne gemäß der vorliegenden Erfindung dargestellt. In den Figuren 9A bis 9D sind die einzelnen Antennenstrukturen in den vier Lagen dargestellt. Figur 10 zeigt einen schematischen Querschnitt durch diese vierlagige Antenne. Es ist zu erkennen, daß sich zwei Lagen innerhalb der mehrlagigen Leiterplatte und zwei Lagen außerhalb der mehrlagigen Leiterplatte befinden.A four-layer antenna according to FIGS of the present invention.

It can be seen that two layers within the multi-layer circuit board and two Layers are outside the multi-layer circuit board.

    Es sollen an dieser Stelle noch einige allgemeine Bemerkungen zu der erfindungsgemäßen Antenne gemacht werden. Die hier vorgestellte mehrlagige Multiband-Antenne besteht aus einer oder mehreren mehrlagigen Leiterplatten. Das Material, aus dem eine dieser Leiterplatten besteht, ist frei wählbar, sollte aber hochfrequenztauglich sein. Es kann im besonderen Fall auch biegsames flexibles Material sein. Auf jeder Lage kann eine Leiterbahn strukturiert sein, die einen Strahler oder ein anderes beliebiges elektrisches Element darstellt.At this point I would like to make a few general comments be made to the antenna according to the invention. This one multi-band antenna presented consists of a or several multilayer printed circuit boards. The material from one of these PCBs is freely selectable, but should be suitable for high frequencies. It can in particular Case also be flexible flexible material. In every situation can be structured a conductor track that a radiator or any other electrical element.

    Die Antenne besteht aus mehr als zwei Lagen, also mindestens aus drei Lagen. Von diesen Lagen liegt mindestens eine innerhalb des Materials. Die Lagen sind vorzugsweise, aber nicht zwingend, parallel zueinander. Sie können jede beliebige Position zueinander einnehmen. Die Lagen können an jeder beliebigen Position der Leiterplatte liegen und jede beliebige auch unterschiedliche Dicke besitzen. Es sind also auch Lagen auf den Stirnseiten und auf den Längsseiten möglich. Weiterhin sind auch schiefe Lagen möglich.The antenna consists of more than two layers, at least from three layers. At least one of these layers lies within of the material. The locations are preferred, but not mandatory, parallel to each other. You can use any position to each other. The layers can be at any Position of the circuit board and any also have different thicknesses. So there are also layers possible on the front and on the long sides. Farther inclined positions are also possible.

    Vorzugsweise besitzt nur eine Leiterbahn (ein Strahler) auf einer Lage einen Speisepunkt. Dieser Speisepunkt wird über ein Kontaktelement mit der HF-Baugruppe des Kommunikationsendgerätes verbundenn.Preferably has only one conductor track (a radiator) a location a feeding point. This dining point is about a contact element with the RF module of the communication terminal connected.

    Alle anderen Strahler werden vorzugsweise durch Kopplung angeregt. Es können sich auch zwei oder mehrere Strahler auf einer Lage befinden.All other radiators are preferably excited by coupling. There can also be two or more radiators a location.

    Es können sich aber auch eine oder mehrere direkte elektrische Verbindungen zwischen einem oder mehreren Strahlern auf verschiedenen Lagen mittels Durchkontaktierung oder Kontaktierung über eine Seitenfläche an jedem beliebigen Punkt hergestellt werden. But there can also be one or more direct electrical ones Connections between one or more radiators different layers by means of through-plating or contacting made over a side surface at any point become.

    Ein derartiges Beispiel mit einer Durchkontaktierung ist in den Figuren 11A bis 11D und 12 gezeigt. Hierbei handelt es sich um eine vierlagige Multibandantenne, deren Antennenstrukturen dem in den Figuren 9A bis 9D und Figur 10 gezeigtem Ausführungsbeispiel entsprechen. Zum Unterschied zu dem vorher beschriebenen Ausführungsbeispiel sind bei diesem Ausführungsbeispiel die in Figur 11A und Figur 11C gezeichneten Lagen mittels einer Durchkontaktierung, wie in Figur 12 zu erkennen ist, miteinander verbunden.Such an example with a via is shown in 11A to 11D and 12 shown. This is what it is about is a four-layer multi-band antenna whose antenna structures that shown in Figures 9A to 9D and Figure 10 Embodiment correspond. In contrast to that previously described embodiment are in this embodiment those drawn in Figure 11A and Figure 11C Layers by means of a plated-through hole, as in FIG recognize is connected.
