Y. COLOMB, P. E. MAYES, IEEE ANTENNAS AND PROPAGATION SOCIETY INTERNATIONAL SYMPOSIUM, Juli 1992, Band 4, Seiten 2077–2080, beschreibt eine Zweibandantenne wie im Oberbegriff des unabhängigen Anspruchs 1 angegeben.Of the Article "Stacked patches with a slot in the common wall for single and dual band operation "(" Stacked Patches with a slot in the common wall for bookbinding and dual band operation "), F. Y. COLOMB, P.E. MAYES, IEEE ANTENNAS AND PROPAGATION SOCIETY INTERNATIONAL SYMPOSIUM, July 1992, Vol. 4, pp. 2077-2080 a dual-band antenna as in the preamble of the independent claim 1 indicated.
Neuerdings ist die Nachfrage nach Antennen für mobile drahtlose Anwendungen dramatisch gestiegen, und es gibt jetzt eine Anzahl von Systemen für drahtlose Kommunikation auf Land- und Satellitenbasis unter Verwendung eines weiten Bereichs von Frequenzbändern. Demgemäß besteht auch ein Bedarf für ein einzelnes Antennenelement mit abstrahlenden Elementen für Patches, die in zwei oder mehr getrennten Frequenzbändern arbeiten können.recently is the demand for antennas for mobile wireless applications has risen dramatically, and there are now a number of systems for wireless Land- and satellite-based communication using a wide range of frequency bands. Accordingly, there is also a need for a single antenna element with radiating elements for patches, which can operate in two or more separate frequency bands.
Hauptaufgabe der Erfindung ist es, eine solche Antenne mit einem Antennenelement zu schaffen, das in wenigstens zwei getrennten Frequenzbändern arbeiten kann, wobei jedes Band vorzugsweise ziemlich breit ist.The main task The invention is to provide such an antenna with an antenna element to create that work in at least two separate frequency bands can, each band is preferably quite wide.
Eine andere Aufgabe ist es, eine Antenne mit einem Antennenelement zu schaffen, das mit Doppelpolarisation arbeitet, um eine gewünschte Diversity der von der Antenne übertragenen oder empfangenen Mikrowellenstrahlung zu erreichen. Eine solche Diversity ist besonders nützlich bei Basisstationsantennen. Die doppelt polarisierten Trägerwellen sollten rechtwinklig zueinander mit einer guten Isolation dazwischen, vorzugsweise besser als 30 dB sein.A Another object is to provide an antenna with an antenna element that works with dual polarization to achieve a desired diversity that transmitted by the antenna or to reach received microwave radiation. Such diversity is especially useful in base station antennas. The double polarized carrier waves should be at right angles to each other with good insulation in between, preferably better than 30 dB.
Die Hauptaufgabe, wie oben angegeben, wird erfüllt durch eine Antenne, wie im Anspruch 1 angegeben.The Main task, as stated above, is fulfilled by an antenna, such as specified in claim 1.
So hat das erste Patch eine Doppelbetriebsfunktion, d. h., es dient als ein Abstrahlungselement aber auch als ein Kopplungselement, um mittels seiner Apertur die Mikrowellenleistung vom Einspeisungsnetz und die Apertur der Groundplane-Schicht zum zweiten Patch zu koppeln.So the first patch has a dual operation function, i. h., it serves as a radiating element but also as a coupling element, by means of its aperture, the microwave power from the feed network and couple the aperture of the groundplane layer to the second patch.
Um eine wirksame Kopplung zu erhalten, ist vorzugsweise ein drittes Patch zwischen der Groundplane-Schicht und dem ersten Patch angeordnet, wobei das dritte Patch dazu dient, die Mikrowellenleistung im zweiten Frequenzband zu koppeln. Das dritte Patch sollte im Wesentlichen die gleiche Größe wie das zweite Patch haben, jedoch kleiner als das erste Patch sein.Around to obtain an effective coupling is preferably a third one Patch disposed between the groundplane layer and the first patch, the third patch being used to control the microwave power in the second Coupling frequency band. The third patch should be essentially the same size as that second patch, but smaller than the first patch.
Doppelpolarisation kann in jedem Frequenzband erreicht werden. Vorteilhafterweise umfasst die Kopplungsvorrichtung an der Groundplane-Schicht eine Apertur in dieser und jede der Aperturen ist kreuzförmig mit zwei sich senkrecht zueinander kreuzenden Schlitzen. Das erste und das zweite Patch sollten dann in Beziehung auf den Mittelpunkt der kreuzförmigen Apertur der Groundplane-Schicht zentriert sein.dual polarization can be achieved in any frequency band. Advantageously the coupling device at the ground plane layer an aperture in this and each of the apertures is cross-shaped with two perpendicular Slits crossing each other. The first and the second patch should then in relation to the center of the cross-shaped aperture of the groundplane layer be centered.
Diese und andere bevorzugte Merkmale werden in den beigefügten Ansprüchen angegeben und ergeben sich aus der folgenden genaueren Beschreibung.These and other preferred features are given in the appended claims and result from the following more detailed description.
Die Erfindung wird nun weiter erläutert mit Bezug auf die beigefügten Zeichnungen, welche eine bevorzugte Ausführungsform der Erfindung zeigen.The Invention will now be further explained with reference to the attached Drawings showing a preferred embodiment of the invention.

Praktische Versuche haben auch gezeigt, dass es möglich ist, eine Rückflussdämpfung von wenigstens 15 dB im niedrigeren Band (GSM) für beide Kanäle zu erreichen. Im höheren Band (DCS) ist die Rückflussdämpfung größer als 10 dB. Ferner waren die Bandbreiten für eine Rückflussdämpfung von mehr als 10 dB 14,3% rings um 920 MHz und 14,7% rings um 1795 MHz. Schließlich erwies sich die Isolation zwischen den zwei Kanälen in jedem Frequenzband als größer als 32 dB.practical Experiments have also shown that it is possible to have a return loss of at least 15 dB in the lower band (GSM) for both channels. In the higher band (DCS), the return loss is greater than 10 dB. Furthermore, the bandwidths for a return loss of more than 10 dB were 14.3% around 920 MHz and 14.7% around 1795 MHz. Finally proved the isolation between the two channels in each frequency band is considered greater than 32 dB.
