Beschreibung von Ausführungsbeispielen Description of exemplary embodiments
Fig. 1 zeigt ein Ausführungsbeispiel einer erfindungsgemäßen Dual-Band- Antenne. Dargestellt ist eine Dual-Band-Antenne 10, welche eine elektrisch leitende Platte 20 aufweist. Die elektrisch leitende Platte 20 weist einen Schlitz 40 auf. Zudem weist die Dual-Band-Antenne 10 eine Hochfrequenz-Leitung 30 zur Kopplung der Dual-Band-Antenne 10 an eine Sende- oder auch Empfangseinheit 33 auf. Fig. 1 shows an embodiment of a dual-band antenna according to the invention. Shown is a dual-band antenna 10, which has an electrically conductive plate 20. The electrically conductive plate 20 has a slot 40. In addition, the dual-band antenna 10 has a high-frequency line 30 for coupling the dual-band antenna 10 to a transmitting or receiving unit 33.
Hierfür ist die Hochfrequenz-Leitung 30 sowohl elektrisch mit dem Schlitz 40 verbunden als auch mit der Sende- oder auch Empfangseinheit 33 verbunden. Die Sende- oder auch Empfangseinheit 33 kann des Weiteren auch direkt auf der leitenden Platte 20 angeordnet sein. Die Hochfrequenz-Leitung 30 ist For this purpose, the high-frequency line 30 is both electrically connected to the slot 40 and connected to the transmitting or receiving unit 33. Furthermore, the transmitting or receiving unit 33 can also be arranged directly on the conductive plate 20. The high frequency line 30 is
beispielsweise ein Koaxialkabel und wird hierbei insbesondere mit dem sogenannten 50-Ohm-lmpedanz-Punkt verbunden. Der Schlitz 40 ist als länglicher, gerader Durchbruch in der elektrisch leitenden Platte 20 ausgestaltet und weist eine Verjüngung 43 auf, welche den Schlitz 40 in einen ersten For example, a coaxial cable and is in particular connected to the so-called 50-ohm impedance point. The slot 40 is configured as an elongated, straight breakthrough in the electrically conductive plate 20 and has a taper 43, which the slot 40 in a first
Abschnitt 41 und einen zweiten Abschnitt 42 unterteilt. Die Verjüngung 43 ist hierbei als einseitiger Vorsprung in den Schlitz 40 hinein ausgestaltet. Bis auf die Verjüngung 43 weist der Schlitz 40 eine im Wesentlichen gleichmäßige Breite auf. Die Verjüngung 43 bewirkt, dass der Schlitz 40 dazu eingerichtet ist, elektromagnetische Signale 15 in einem ersten Frequenzbereich 11 sowie in einem davon verschiedenen zweiten Frequenzbereich 12 auszusenden oder auch zu empfangen. Die Verjüngung 43 wirkt für den zweiten Frequenzbereich im Prinzip als Kurzschluss mit kleiner Impedanz und dient an diesem Punkt alsSection 41 and a second section 42 divided. The taper 43 is designed here as a one-sided projection in the slot 40 into it. Except for the taper 43, the slot 40 has a substantially uniform width. The taper 43 causes the slot 40 to be adapted to emit or receive electromagnetic signals 15 in a first frequency range 11 as well as in a different second frequency range 12. The taper 43 acts for the second frequency range in principle as a short circuit with low impedance and is used at this point as
Serienresonanz, wodurch für den zweiten Frequenzbereich lediglich der erste Abschnitt 41 des Schlitzes 40 als eigentlicher Strahler wirkt. Für den ersten Frequenzbereich 11 dient dagegen der komplette Schlitz 40 als Strahler. Zur Einstellung der beiden Frequenzbereiche weist der Schlitz 40 eine Series resonance, whereby only the first portion 41 of the slot 40 acts as the actual radiator for the second frequency range. For the first frequency range 11, however, the complete slot 40 serves as a radiator. For adjusting the two frequency ranges, the slot 40 has a
entsprechende Gesamtlänge 45 auf und zudem ist die Verjüngung 43 corresponding overall length 45 and also the taper 43
entsprechend angeordnet. Die Gesamtlänge 45 des Schlitzes 40, die sich aus dem ersten Abschnitt 41, dem zweiten Abschnitt 42 und der Verjüngung 43 zusammensetzt, entspricht hierbei der halben Wellenlänge des ersten arranged accordingly. The total length 45 of the slot 40, which is composed of the first portion 41, the second portion 42 and the taper 43, in this case corresponds to half the wavelength of the first
Frequenzbereichs 11. Liegt dieser erste Frequenzbereich 11 beispielsweise zwischen 2,4GHz und 2,48GHz beträgt die Wellenlänge in etwa 12,5cm, womit die Gesamtlänge 45 des Schlitzes 40 in etwa 6,25cm ist. Des Weiteren ist die Verjüngung 43 derartig angeordnet, dass der erste Abschnitt 41, in welchem die Hochfrequenz-Leitung 30 elektrisch mit dem Schlitz 40 verbunden ist, halb so lang wie die Wellenlänge des zweiten Frequenzbereichs 12 ist. Liegt dieser zweite Frequenzbereich 12 beispielsweise zwischen 5,180GHz und 5,825GHz beträgt die Wellenlänge in etwa 5,2cm, weshalb der erste Abschnitt 41 des Schlitzes 40 in etwa 2,6cm lang ist. Des Weiteren lässt sich der zweite Frequency range 11. If this first frequency range 11 is, for example, between 2.4 GHz and 2.48 GHz, the wavelength is approximately 12.5 cm, so that the total length 45 of the slot 40 is approximately 6.25 cm. Further, the taper 43 is arranged such that the first portion 41, in which the high-frequency line 30 is electrically connected to the slot 40, is half as long as the wavelength of the second frequency range 12. For example, this second frequency range 12 is between 5.185 GHz and 5.825 GHz For example, the wavelength is about 5.2 cm, so the first portion 41 of the slot 40 is about 2.6 cm long. Furthermore, the second one can be
Frequenzbereich 12 noch durch die Ausgestaltung der Verjüngung 43 anpassen. So verändert sich beispielsweise bei einem Vorsprung, welcher weiter in den Schlitz 40 hineinragt, der Resonanzbereich des zweiten Frequenzbereichs 12 und wird entsprechend größer. Auch lassen sich über die Breite der Verjüngung 44 der erste Frequenzbereich 11 sowie der zweite Frequenzbereich 12 anpassen. Die Gesamtlänge 45 des Schlitzes 40 des Schlitzes 40 sowie die Länge des ersten Abschnitts 41 kann unter Erhalt der beiden Frequenzbereiche 11, 12 von den oben genannten Beispielen abweichen, wenn der Schlitz 40 mit einem Material, welches eine von Luft verschiedene Dielektrizitätskonstante aufweist, ausgefüllt ist. Frequency range 12 nor adapt by the configuration of the taper 43. For example, in the case of a projection which projects further into the slot 40, the resonance range of the second frequency range 12 changes and becomes correspondingly larger. Also, the first frequency range 11 and the second frequency range 12 can be adapted via the width of the taper 44. The total length 45 of the slot 40 of the slot 40 and the length of the first portion 41 may differ from the above-mentioned examples to obtain the two frequency ranges 11, 12 when the slot 40 is filled with a material having a dielectric constant other than air ,
In einem alternativen, bildlich nicht dargestellten Ausführungsbeispiel kann der Schlitz 40 auch gebogen ausgestaltet sein. In an alternative, not illustrated embodiment, the slot 40 may also be configured bent.
In einem weiteren alternativen, bildlich nicht dargestellten Ausführungsbeispiel kann die Hochfrequenz-Leitung 30 anstatt als Koaxialkabel als Streifenleitung oder Triplate-Leitung ausgestaltet sein. Hierbei ist es dann insbesondere von Vorteil, wenn die Sende- oder auch Empfangseinheit 33 direkt auf der leitenden Platte 20 angeordnet ist, da hierdurch das Koaxialkabel entfallen kann, was wiederum zu Materialeinsparungen sowie Verringerung des Platzbedarfs führt. In a further alternative embodiment, not illustrated, the high-frequency line 30 may be configured instead of a coaxial cable as a stripline or triplate line. In this case, it is particularly advantageous if the transmitting or receiving unit 33 is arranged directly on the conductive plate 20, since this can eliminate the coaxial cable, which in turn leads to material savings and reduction of space requirements.

Diese beiden Resonanzbereiche stellen den ersten Frequenzbereich 11 und den zweiten Frequenzbereich 12 der Dual-Band- Antenne 10 dar, wobei der erste Frequenzbereich 11 etwa zwischen 2,4GHz und 2,48GHz sowie der zweite Frequenzbereich 12 etwa zwischen 5,180GHz und 5,825GHz liegt. Shown is the input matching of the dual band antenna 10 of FIG. 1 over the frequency. It can clearly be seen that the dual-band antenna 10 has two resonance regions. These two resonance ranges represent the first frequency range 11 and the second frequency range 12 of the dual-band antenna 10, wherein the first frequency range 11 is approximately between 2.4 GHz and 2.48 GHz and the second frequency range 12 is approximately between 5.125 GHz and 5.825 GHz.

elektromagnetischen Signale 15 aus dem Gehäuse 110 heraus bzw. in das Gehäuse 110 hinein gelangen können. electromagnetic signals 15 can pass out of the housing 110 or into the housing 110.
In einem alternativen, bildlich nicht dargestellten Ausführungsbeispiel ist hinter der Dual-Band-Antenne 10 noch ein metallischer Reflektor angeordnet. Dieser Reflektor ist hierbei parallel zur elektrisch leitenden Platte 20 der Dual-Band- Antenne 10 mit einem Abstand von etwa 2cm angeordnet. Durch diesen In an alternative, not illustrated embodiment, a metallic reflector is still behind the dual-band antenna 10 is arranged. This reflector is in this case arranged parallel to the electrically conductive plate 20 of the dual-band antenna 10 at a distance of about 2cm. Through this
Reflektor kann das Richtdiagramm der Dual-Band-Antenne 10 optimiert werden, um die elektromagnetischen Signale 15 gezielt über die Ausnehmung 115 zu senden bzw. zu empfangen. Reflector, the directional diagram of the dual-band antenna 10 can be optimized to selectively send the electromagnetic signals 15 via the recess 115 and receive.
In einem weiteren alternativen, bildlich nicht dargestellten Ausführungsbeispiel kann die Abdeckplatte 117 auch derartig ausgestaltet und angeordnet sein, dass diese die Ausnehmung 115 in ihrer Fläche vollständig ausfüllt. In a further alternative, not illustrated embodiment, the cover plate 117 may also be configured and arranged such that it completely fills the recess 115 in its surface.
In einem weiteren alternativen, bildlich nicht dargestellten Ausführungsbeispiel kann das Gehäuse 110 der Vorrichtung 10 auch mehrere Ausnehmungen und entsprechend mehrere Dual-Band-Antennen aufweisen. Hierdurch kann ein sogenannter MI MO- Betrieb (Multiple Input Multiple Output) ermöglicht werden, indem diese Dual-Band-Antennen mittels Antennendiversität, z. B. In a further alternative, not illustrated embodiment, the housing 110 of the device 10 may also have a plurality of recesses and correspondingly more dual-band antennas. This allows a so-called MI MO operation (Multiple Input Multiple Output) are made possible by these dual-band antennas by means of antenna diversity, z. B.
