In Hinsicht auf die Entwicklung in der Mobilfunktechnologie werden Antennen benötigt, welche in der Lage sind mehrere Frequenzbänder gleichzeitig abzudecken. With regard to the development in the mobile technology antennas are needed which are able to cover multiple frequency bands simultaneously. Außerdem verlangt der Markt nach immer kleineren und billigeren Mobilfunkgeräten. Moreover, the market demands smaller and cheaper mobile devices. 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. Therefore, antennas are required to have a small footprint, are interpretable and cheap for function in several frequency bands or a wide-band frequency range and in a reproducible manner without any problems.

Die bisherigen Konzepte, wie z. The previous concepts such. 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. For example, the helix wire antennas or microstrip antennas all have the disadvantage that they either have too high a space or the tunability is not readily applied to a multi-band capability is possible.

Aus der EP-A-0 746 054 ist zwar eine Antennenanordnung gemäß dem Oberbegriff bekannt, jedoch weist diese Antenne keine Multibandfähigkeit auf. Although an antenna arrangement according to the preamble is known from EP-A-0746054, however, this antenna not multiband capability.

Aufgabe der vorliegenden Erfindung ist es, eine Antenne der eingangs genannten Art anzugeben, die einen geringen Platzbedarf aufweist, für mehrere Frequenzbänder auslegbar ist und billig herstellbar ist. Object of the present invention is to provide an antenna of the type mentioned, which has a low space requirement, is interpretable for a plurality of frequency bands and is inexpensive to manufacture.

Diese Aufgabe wird für die eingangs genannte Antenne dadurch gelöst, daß die einzelnen Antennenstrukturen zur Ausbildung eines Strahlers geformt sind. This object is achieved for the aforementioned antenna characterized in that the individual antenna structures are shaped to form a radiator.

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 cheap to produce, requires little space and is easily adaptable for operation in multiple frequency bands or a wide-band frequency range.

Im Gegensatz zu der aus EP-A-0 746 054 bekannten Antennenanordnung, bei der sich jeweils Strahlungsstrukturen und Koppelerstrukturen auf den einzelnen Lagen abwechseln und welche keine Multibandfähigkeit aufweist, weist jede einzelne Lage eine unterschiedlichen Strahlungsstruktur auf, so dass auf einfache Art und Weise eine Multibandfähigkeit hergestellt werden kann. Unlike the device known from EP-A-0746054 antenna arrangement in which alternate with each radiation structures and Koppelerstrukturen on the individual layers and which does not have multi-band capability, each individual layer to a different radiating structure, so that in a simple manner, a multiband capability can be produced.

Aus der US-A-5 075 691 ist eine laminar aufgebaute Multibandantenne bekannt. From US-A-5075691 a laminar structured multi-band antenna is known. Diese Multibandantenne besteht aber aus einer nicht selbst strahlenden kapazitiven Koppelvorrichtung, welche verschiedene Resonatoren/Antennen anregt. These multi-band antenna consists of a non-self-radiating capacitive coupling device that stimulates different resonators / antennas. Beim Anmeldungsgegenstand ist bereits die Koppelvorrichtung ein Strahler, wobei die Verkoppelung durch E- und H-Felder erfolgt. When subject application, the coupling device is already a radiator, wherein the coupling of is performed by E- and H-fields. Im Gegensatz zum Anmeldungsgegenstand befinden sich alle Strahlungselemente in einer Ebene. In contrast to the subject application are all radiating elements in a plane.
