Description

Die Erfindung betrifft eine dielektrische Resonatorantenne (DRA) mit einer elektrisch leitenden Schicht in einer Symmetrieebene.The invention relates to a dielectric resonator antenna (DRA) with an electrical conductive layer in a plane of symmetry.

Außerdem bezieht sich die Erfindung noch auf einen Sender und Empfänger mit einer dielektrischen Resonatorantenne mit einer elektrisch leitenden Schicht in einer Symmetrieebene sowie auf ein Mobilfunkgerät mit einer solchen Antenne.The invention also relates to a transmitter and receiver with a dielectric resonator antenna with an electrically conductive layer in a plane of symmetry as well as a mobile device with such an antenna.

Dielektrische Resonatorantennen (DRA) sind als miniaturisierte Antennen aus Keramik oder einem anderen Dielektrikum für Mikrowellenfrequenzen bekannt. In einem dielektrischen Resonator, dessen Dielektrikum mir einer Dielektrizitätszahl von εr >> 1 von Luft umgeben ist, besitzt dieser ein diskretes Spektrum von Eigenfrequenzen und Eigenmoden. Im Gegensatz zu einem Resonator, der bei Vermeidung von Abstrahlungsverlusten eine sehr hohe Güte aufweist, steht bei einer Resonatorantenne die Abstrahlung von Leistung im Vordergrund. Da keine leitenden Strukturen als strahlendes Element verwendet werden, kann sich der Skineffekt nicht negativ auswirken. Daher weisen solche Antennen niedrige ohmsche Verluste bei hohen Frequenzen auf. Durch die Verwendung von Materialien mit hoher Dielektrizitätszahl kann weiterhin ein kompakter, miniaturisierter Aufbau erreicht werden. In der Figur 1 ist eine solche DR-Antenne 1 in da als beispielhaft betrachteten Grundform dargestellt. Neben der Form als Quader sind auch andere Formen möglich, wie zum Beispiel zylinder- oder kugelförmige Geometrien. Dielektrische Resonatorantennen sind resonante Bauteile, die nur in einem schmalen Band um eine ihrer Resonanzfrequenzen arbeiten. Das Problem der Miniaturisierung einer Antenne ist äquivalent dazu, die Arbeitsfrequenz bei gegebenen Antennenabmessungen zu erniedrigen. Deshalb wird die niedrigste Resonanz (TEz 111-Mode) verwendet. Diese Mode besitzt eine Ebene, in der die Tangentialkomponente des elektrischen Feldes verschwindet, die Symmetrieebene 2 genannt wird. Wenn die Antenne in der Symmetrieebene 2 halbiert und eine elektrisch leitfähige Fläche 3 angebracht wird (beispielsweise eine Metallplatte), bleibt die Resonanzfrequenz gleich der einer Antenne mit den ursprünglichen Abmessungen. Dies ist in der Figur 2 dargestellt. Eine weitere Miniaturisierung kann bei dieser Antenne mittels eines Dielektrikums mit hoher Dielektrizitätszahl εr erzielt werden. Dabei wird vorzugsweise ein Material mir geringen dielektrischen Verlusten ausgewählt.Dielectric resonator antennas (DRA) are known as miniaturized antennas made of ceramic or another dielectric for microwave frequencies. In a dielectric resonator, the dielectric of which is surrounded by air with a dielectric constant of ε r >> 1, it has a discrete spectrum of natural frequencies and natural modes. In contrast to a resonator, which has a very high quality while avoiding radiation losses, the radiation of power is in the foreground with a resonator antenna. Since no conductive structures are used as the radiating element, the skin effect cannot have a negative effect. Such antennas therefore have low ohmic losses at high frequencies. Through the use of materials with a high dielectric constant, a compact, miniaturized structure can also be achieved. Such a DR antenna 1 is shown in FIG. 1 in the basic form considered as an example. In addition to the shape as a cuboid, other shapes are also possible, such as cylindrical or spherical geometries. Dielectric resonator antennas are resonant components that only work in a narrow band around one of their resonance frequencies. The problem of antenna miniaturization is equivalent to lowering the operating frequency for given antenna dimensions. Therefore the lowest resonance (TE z 111 mode) is used. This mode has a plane in which the tangential component of the electric field disappears, which is called plane of symmetry 2. If the antenna is halved in the plane of symmetry 2 and an electrically conductive surface 3 is attached (for example a metal plate), the resonance frequency remains the same as that of an antenna with the original dimensions. This is shown in Figure 2. A further miniaturization can be achieved with this antenna by means of a dielectric with a high dielectric constant ε r . A material with low dielectric losses is preferably selected.

Dabei wird ein Überblick über die Moden und die Strahlungscharakteristik für verschiedene Formen, wie zylindrische, kugelförmige und rechtwinklige DRA's gegeben. Es werden für unterschiedliche Formen die möglichen Moden und Symmetrieebenen gezeigt (siehe Figur 4, 5, 6 und Seite 240, linke Spalte, Zeilen 1-21). In der Figur 9 und der zugehörigen Beschreibung wird insbesondere eine quaderförmige dielektrische Resonatorantenne beschrieben. Mittels einer Metallfläche in der x-z-Ebene bei y=0 oder der y-z-Ebene bei x=0 kann die ursprüngliche Struktur halbiert werden, ohne die Feldverteilung oder andere Resonanzcharakteristika für die Tez 111-Mode zu verändern (Seite 244, rechte Spalte, Zeilen 1-7). Die DRA wird über eine Zuleitung mit Mikrowellenleistung angeregt, indem sie in das Streufeld in der Nähe einer Mikrowellenleitung (beispielsweise eine Microstripleitung oder das Ende einer Koaxialleitung) eingebracht wird.Such a dielectric resonator antenna is described in the article

Journal of Microwave and Millimeter-wave Computer-aided Engineering, Vol. 4, No. 3, 1994, pages 230-247, which provides an overview of the modes and the radiation characteristics for different shapes, such as cylindrical, spherical and right-angled DRAs, and shows the possible modes and symmetry levels for different shapes (see FIGS. 4, 5, 6 and page 240) , left column, lines 1-21) A cuboid dielectric resonator antenna is described in particular in Figure 9. The original can be described by means of a metal surface in the xz plane at y = 0 or the yz plane at x = 0 Structure can be halved without changing the field distribution or other resonance characteristics for the Te z 111 mode (page 244, right column, lines 1-7) excited via a feed line with microwave power, by introducing it into the stray field in the vicinity of a microwave line (for example a microstrip line or the end of a coaxial line).

Bei dieser Art der Einkopplung der Leistung ist die für einen guten Wirkungsgrad notwendige Impedanzanpassung der dielektrischen Resonatorantenne an die Zuleitung schwierig, da die Anpassung stark von der Position der Antenne zur Zuleitung abhängt. Die Abweichung der relativen Position der Antenne zur Zuleitung schwankt aber insbesondere bei einer automatischen Fertigung sehr stark.With this type of coupling the power is necessary for good efficiency Impedance matching of the dielectric resonator antenna to the supply line difficult, since the adaptation depends strongly on the position of the antenna to the feed line. The deviation however, the relative position of the antenna to the feed line fluctuates in particular an automatic production very strong.

Die Aufgabe der Erfindung besteht darin, bei einer dielektrischen Resonatorantenne eine bessere Kopplung an eine Zuleitung zu schaffen.The object of the invention is to provide a dielectric resonator antenna to create better coupling to a supply line.

Die Aufgabe wird dadurch gelöst, daß in der Symmetrieebene wenigstens ein, von der elektrisch leitenden Schicht isolierter, elektrischer Kontakt vorgesehen ist, und daß die elektrische Schicht und der elektrische Kontakt zur Verbindung der dielektrischen Resonatorantenne mir wenigstens einer Zuleitung für ein zu sendendes oder zu empfangenes Signal vorgesehen sind. Auf diese Weise entstehen in einer Ebene zwei fest mir da dielektrischen Resonatorantenne verbundene elektrische Kontakte, die zur Einkopplung da Leistung mit der DRA verbunden werden können. Eine erfindungsgemäße Antenne kann mit anderen Komponenten auf einer Platine (PCB) in der bekannten SMD-Technik (Verlöten auf der Oberfläche der Platine) montiert werden. Diese SMD-fähige DRA kann fest mit den Zuleitungen auf der Platine verlötet werden, wodurch eine deutlich bessere Einkopplung als beim Einbringen in das Streufeld einer Zuleitung erzielt wird. Die Impedanzanpassung hängt wesentlich weniger von der genauen Positionierung der Antenne auf der Platine ab, als beim Einkoppeln in ein Streufeld, bei dem die Anpassung stark vom Abstand der Antenne von der Zuleitung abhängt.The object is achieved in that at least one in the plane of symmetry electrically conductive layer insulated, electrical contact is provided, and that the electrical layer and the electrical contact for connecting the dielectric resonator antenna me at least one supply line for one to be sent or received Signal are provided. In this way, two are firmly established on one level dielectric resonator antenna connected electrical contacts used for coupling because power can be connected to the DRA. An antenna according to the invention can with other components on a circuit board (PCB) in the known SMD technology (Soldering on the surface of the board). This SMD-capable DRA can firmly soldered to the leads on the board, making a much better Coupling is achieved than when introducing into the stray field of a supply line. The impedance matching depends much less on the exact positioning of the antenna the board than when coupling into a stray field, in which the adaptation is very different Distance of the antenna depends on the supply line.

Bei einer vorteilhaften Ausführungsform ist jeweils eine Metallschicht zur Bildung der elektrisch leitenden Schicht in der Symmetrieebene und des elektrischen Kontaktes vorgesehen. Metallschichten eignen sich aufgrund ihrer guten Fertigungseigenschaften und elektrischen Leitfähigkeit gut zur Realisierung der Verbindung mit einer Zuleitung.In an advantageous embodiment, a metal layer for forming the provided electrically conductive layer in the plane of symmetry and the electrical contact. Metal layers are suitable due to their good manufacturing properties and electrical conductivity good for realizing the connection with a supply line.

In einer weiteren Ausgestaltung ist eine Metallschicht auf einer an die Symmetrieebene angrenzenden Seite der DRA zur Verbindung mit dem elektrischen Kontakt in der Symmetrieebene vorgesehen. Auf diese Weise wird mit der Erweiterung durch die Metallschicht eine besonders gute Anregung der dielektrischen Resonatorantenne erreicht. Beispielsweise kann bei einer quaderförmigen Antenne mit der Symmetrieebene als Grundfläche der elektrische Kontakt auf einer angrenzenden Stirnseite angebracht werden. Dabei wird die Metallschicht über die Kante auf die Grundfläche durchgeführt, so daß in der Symmetrieebene ein Lötpunkt entsteht, der für die Oberflächenmontage verwendet werden kann. Dieser Lötpunkt ist natürlich von der elektrisch leitenden Schicht isoliert, was vorzugsweise durch Aussparen einer kleinen Fläche beim Metallisieren der Symmetrieebene geschieht. Dabei ist vorteilhafterweise eine Silberpaste zur Bildung der Metallschicht durch Einbrennen in das Material der DRA vorgesehen.In a further embodiment, a metal layer is on a plane of symmetry adjacent side of the DRA for connection to the electrical contact in the Plane of symmetry provided. This way, with the expansion through the Metal layer achieved a particularly good excitation of the dielectric resonator antenna. For example, in the case of a cuboid antenna with the plane of symmetry as Base of the electrical contact to be attached to an adjacent end face. The metal layer is carried over the edge to the base, so that in a plane of symmetry is created on the plane of symmetry, which is used for surface mounting can be. This soldering point is of course isolated from the electrically conductive layer, which is preferably by omitting a small area when metallizing the plane of symmetry happens. A silver paste is advantageously used to form the metal layer provided by burning into the material of the DRA.

In einer bevorzugten Weiterbildung ist als Material für die dielektrische Resonatorantenne eine Keramik aus (Ba, Nd, Gd)TiO3 vorgesehen. Dieses keramische Material weist alle wichtigen Eigenschaften für die dielektrische Resonatorantenne wie hohe Dielektrizitätszahl, niedrige dielektrische Verluste und einen niedrigen dielektrischen Temperaturkoeffizienten auf.In a preferred development, a ceramic made of (Ba, Nd, Gd) TiO 3 is provided as the material for the dielectric resonator antenna. This ceramic material has all the important properties for the dielectric resonator antenna, such as high dielectric constant, low dielectric losses and a low dielectric temperature coefficient.

Weitere vorteilhafte Ausgestaltungen sind in den übrigen Ansprüchen enthalten.Further advantageous configurations are contained in the remaining claims.

Weiterhin wird die Aufgabe der Erfindung noch durch einen Sender und einen Empfänger sowie ein Mobilfunkgerät gelöst, bei dem in der Symmetrieebene der Antenne wenigstens ein, von der elektrisch leitenden Schicht isolierter, elektrischer Kontakt vorgesehen ist, und die elektrische Schicht und der elektrische Kontakt zur Verbindung der dielektrischen Resonatorantenne mit wenigstens einer Zuleitung für ein zu sendendes oder zu empfangenes Signal vorgesehen sind.Furthermore, the object of the invention by a transmitter and a receiver as well as a mobile radio device in which at least in the plane of symmetry of the antenna an electrical contact insulated from the electrically conductive layer is provided, and the electrical layer and the electrical contact for connecting the dielectric Resonator antenna with at least one feed line for one to be transmitted or received Signal are provided.

In der Figur 3 ist eine dielektrische Resonatorantenne (DRA) 4 mit einer metallischen Schicht 5 in einer Symmetrieebene dargestellt. Weiterhin besitzt der Keramikquader der DRA 4 eine zweite Metallisierung 6 an einer Stirnseire. Die zweite Metallisierung 6 besitzt einen Lötpunkt 7, der sich in der Symmetrieebene elektrisch isoliert von der Metallschicht 5 befindet. Der Lötpunkt 7 bildet den zusätzlichen elektrischen Kontakt in der Symmetrieebene. Dazu wird zunächst die Symmetrieebene, in der die Tangentialkomponente des elektrischen Feldes der gewünschten Eigenmode (niedrigste Resonanz bei TEz 111-Mode) verschwindet, mit einer fest mit dem Dielektrikum verbundenen Metallisierung versehen. Dies geschieht vorzugsweise mit einer Silberpaste, die in die Keramik eingebrannt wird. Die zweite Metallisierung 6 an der Stirnseire wird auf die gleiche Weise angebracht. Diese Metallisierungen 5,6,7 erlauben eine Oberflächenmontage (Surface Mount Device, SMD), also das flache Auflöten elektronischer Komponenten auf einer Platine (Printed Circuit Board PCB) mittels eines Wellen-Lötbades oder eines Reflow-Prozesses.FIG. 3 shows a dielectric resonator antenna (DRA) 4 with a metallic layer 5 in a plane of symmetry. Furthermore, the ceramic cuboid of the DRA 4 has a second metallization 6 on one end face. The second metallization 6 has a soldering point 7, which is electrically insulated from the metal layer 5 in the plane of symmetry. The solder point 7 forms the additional electrical contact in the plane of symmetry. For this purpose, the plane of symmetry in which the tangential component of the electric field of the desired eigenmode (lowest resonance in TE z 111 mode) disappears is provided with a metallization firmly connected to the dielectric. This is preferably done with a silver paste that is burned into the ceramic. The second metallization 6 on the end face is applied in the same way. These metallizations 5, 6, 7 allow surface mounting (surface mount device, SMD), that is, the flat soldering of electronic components on a printed circuit board (printed circuit board PCB) by means of a wave solder bath or a reflow process.

In der Figur 4 ist eine mit Metallisierungen 5 und 6 versehene DRA 4 dargestellt, die in Oberflächenmontagetechnik auf eine Platine 8 mit einer koplanaren Streifenleitung 9, 10, 11 verlötet wurde. Die Metallisierung 6 auf der Stirnseite wird dabei am nach der Montage nicht mehr zu sehenden Lötpunkt 7 mit einer Zuleitung 9 elektrisch verbunden. Die Metallisierung der Symmetrieebene 5 wird an zwei Lötpunkten mit den auf Masse liegenden Flächen 10 und 11 der koplanaren Leitung 9, 10 11 verbunden. Eine so montierte Antenne 4 weist eine gute Kopplung mit der Zuleitung 9, 10, 11 mit einer sehr guten Impedanzanpassung auf (Return-Loss von -35dB), wodurch ein sehr guter Wirkungsgrad erreicht wird. Die guten Werte für die Impedanzanpassung sind unempfindlich gegen Schwankungen in der genauen Form und Größe der Metallisierungen und der Position der Antenne auf der Platine 8.FIG. 4 shows a DRA 4 provided with metallizations 5 and 6 Surface mounting technology on a circuit board 8 with a coplanar strip line 9, 10, 11 was soldered. The metallization 6 on the end face is on after assembly Soldering point 7, which can no longer be seen, is electrically connected to a lead 9. The Metallization of the plane of symmetry 5 is at two solder points with the ones lying on ground Surfaces 10 and 11 of the coplanar line 9, 10 11 connected. One so assembled Antenna 4 has a good coupling with the feed line 9, 10, 11 with a very good one Impedance adjustment to (return loss of -35dB), which makes it very efficient is achieved. The good values for the impedance matching are insensitive to Variations in the exact shape and size of the metallizations and the position of the Antenna on the board 8.

Damit werden folgende Vorteile erreicht. Die Antenne 4 wird fest mit den Leiterbahnen 9, 10, 11 der Zuführungsplatine 8 verlötet. Das Verlöten geschieht flach auf der Oberfläche der Platine, also in der als Fertigungstechnik der Elektronikindustrie bekannten SMD-Technik. Damit kann die Montage der Antenne 4 mit anderen Bauteilen kombiniert werden. Weiterhin weist eine derart montierte DRA 4 eine sehr gute Impedanzanpassung an die Zuleitung 9, 10, 11 auf, die unempfindlich gegen Ungenauigkeiten in der Positionierung der DRA 4 ist. Die beschriebene DRA 4 kann vorzugsweise durch einen Quader der Abmessungen 15x5x6mm3 aus einer (Ba, Nd, Gd)TiO3 Keramik realisiert werden. Dieses Material ist Hochfrequenz geeignet, hat eine Dielektrizitätszahl von er=85, niedrige dielektrische Verluste von tanδ=4x10-4 und einen niedrigen dielektrischen Temperaturkoeffizienten von τε = -30ppm/°C (NP0-Charakteristik). Die Metallisierungen 5 und 6 werden mittels einer Silberpaste hergestellt, die bei einer Temperatur von 700°C eingebrannt wird, so daß eine geschlossene, hoch leitfähige metallische Schicht entsteht. Die Microstripleitung 9, 10, 11 kann auf einem Standard Platinensubstrat 8 mit einem Wellenwiderstand von 50 Ω realisiert werden. Die Arbeitsfrequenz einer solchen DRA 4 liegt bei 2,1 GHz, so daß sie insbesondere für Anwendungen im Mobilfunkbereich geeignet ist.The following advantages are achieved. The antenna 4 is firmly soldered to the conductor tracks 9, 10, 11 of the feed board 8. The soldering is done flat on the surface of the board, i.e. in the SMD technology known as manufacturing technology in the electronics industry. The assembly of the antenna 4 can thus be combined with other components. Furthermore, a DRA 4 mounted in this way has a very good impedance matching to the feed line 9, 10, 11, which is insensitive to inaccuracies in the positioning of the DRA 4. The described DRA 4 can preferably be realized by a cuboid measuring 15x5x6mm 3 made of (Ba, Nd, Gd) TiO 3 ceramic. This material is suitable for high frequencies, has a dielectric constant of er = 85, low dielectric losses of tanδ = 4x10 -4 and a low dielectric temperature coefficient of τ ε = -30ppm / ° C (NP0 characteristic). The metallizations 5 and 6 are produced by means of a silver paste, which is baked at a temperature of 700 ° C, so that a closed, highly conductive metallic layer is formed. The microstrip line 9, 10, 11 can be implemented on a standard circuit board substrate 8 with a characteristic impedance of 50 Ω. The working frequency of such a DRA 4 is 2.1 GHz, so that it is particularly suitable for applications in the mobile radio sector.
