Abstract
Description
Stand der TechnikState of technology
Die Erfindung geht aus von einer Antennenanordnung bestehend aus einem leitenden Zylinder, der auf eine leitende Fläche aufgesetzt ist.The The invention is based on an antenna arrangement consisting of a conductive cylinder, which is mounted on a conductive surface.
Insbesondere für den Empfang von Satellitendiensten wie SDARS oder GPS sind Antennen vorteilhaft, die einfach und kompakt aufbaubar sind. Zusätzlich muss die Strahlcharakteristik, das heißt das Antennediagramm, an die Erfordernisse der verschiedenen Dienste einstellbar sein. In der Regel werden heutzutage Patch-Antennen verwendet, die sowohl kompakt und kostengünstig hergestellt werden können, als auch die für die Satellitendienste geforderte Polarisation (links/rechts zirkular) bereitstellen können. Der zusätzliche Empfang von vertikal polarisierten Signalen bei Elevationswinkeln zwischen 0° und 10° scheitert bei dieser Art von Antennen meist an einem zu geringen Gewinn.Especially for the Reception of satellite services such as SDARS or GPS are advantageous antennas, which are simple and compact buildable. In addition, the beam characteristic, that means that Antenna diagram, to the needs of different services be adjustable. Usually these days patch antennas used, which can be made both compact and inexpensive than also for the satellite services required polarization (left / right circular) can provide. The additional Reception of vertically polarized signals at elevation angles between 0 ° and 10 ° fails in this type of antennas usually at a low profit.
Die zurzeit eingesetzten Antennen, wie zum Beispiel Patch-Antennen, weisen in der Regel die Eigenschaften auf, dass sie einen maximalen Gewinn im Zenit (90° Elevation) besitzen, der zu kleinen Elevationswinkeln rasch abfällt. Bei einigen Systemen ist es allerdings sinnvoll, den maximalen Gewinn zu kleineren Elevationswinkeln (um 30°) zu verschieben, sodass auch in Randbereichen ausreichend Gewinn zur Verfügung steht. Dies ist zum Beispiel sinnvoll bei geostationären Satellitensystemen, die durch ihren Bahnverlauf ihr Versorgungsgebiet nur unter geringem Elevationswinkel versorgen können. Aus diesen niedrigen Elevationswinkeln resultieren meist auch Empfangsprobleme in abgeschatteten Bereichen wie Städte oder Bergregionen. Um dennoch einen Empfang zu ermöglichen, werden Repeater eingesetzt, die im gleichen Frequenzbereich arbeiten aber eine andere Polarisation (vertikal) verwenden.The currently used antennas, such as patch antennas, usually have the characteristics that they have a maximum Profit at the zenith (90 ° elevation) possess, which drops rapidly to small elevation angles. at However, it makes sense for some systems to get the maximum profit to move to smaller elevation angles (by 30 °), so too in marginal areas sufficient profit is available. This is for example useful in geostationary Satellite systems, which by their trajectory their supply area can supply only at low elevation angle. Out of these low ones Elevation angles usually also result in reception problems in shaded areas Areas like cities or mountainous regions. In order nevertheless to enable a reception, Repeaters are used, but they work in the same frequency range use a different polarization (vertical).

Mit den Maßnahmen des Anspruchs 1, das heißt auf der der leitenden Fläche abgewandten Stirnfläche des Zylinders sind radiale Schlitze vorgesehen, die durch die radialen Schlitze gebildeten Segmente oder die Schlitze selbst werden einzeln gespeist, die Höhe des Zylinders wird im Bereich kleiner als der Hälfte der Betriebswellenlänge so gewählt, dass die Strahlungscharakteristik im Bereich außerhalb der Zylinderachse einen höheren Antennengewinn aufweist als im Bereich der Zylinderachse, ist es möglich, insbesondere bei vertikaler Polarisation einen hohen Antennengewinn bei niedrigen Elevationswinkeln zwischen 0° und 10° zu erreichen. Je nach gewählter Höhe des Zylinders kann der Gewinn im Elevationsbereich so eingestellt werden, dass er bei niedrigen Elevationswinkeln angehoben wird. Andererseits stellt die erfindungsgemäße Antenne neben einer linkszirkularen Polarisation auch einen hohen Gewinn der vertikalen Anteile bei sehr niedrigen Elevationswinkeln zwischen 0° und 30° am gleichen Port zur Verfügung. Die Abmessungen der im Folgenden beschriebenen Antenne können weiter reduziert werden, indem die Antenne auf einem Substrat mit hoher Dielektrizitätszahl aufgebaut wird und/oder mit einem derartigen Material umgeben wird.With the measures of claim 1, that is on the conductive surface opposite end face The cylinder radial slots are provided by the radial Slits formed segments or the slots themselves are fed individually, the height of the cylinder is chosen in the range less than half the operating wavelength so that the radiation characteristic in the area outside the cylinder axis a higher Antenna gain than in the area of the cylinder axis, it is possible, especially with vertical polarization a high antenna gain at low elevation angles between 0 ° and 10 °. Depending on the selected height of the cylinder the gain in the elevation range can be adjusted so that it is raised at low elevation angles. on the other hand represents the antenna according to the invention in addition to a left circular polarization also a high profit the vertical proportions at very low elevation angles between 0 ° and 30 ° at the same Port available. The dimensions of the antenna described below can be further reduced be built by the antenna on a substrate with a high dielectric constant is surrounded and / or with such a material.

Die Höhe des Zylinders wird im Bereich kleiner als der Hälfte der Betriebswellenlänge so gewählt, dass die Strahlungscharakteristik im Bereich außerhalb der Zylinderachse, insbesondere am Außenrand, einen höheren Antennengewinn g aufweist als im Bereich der Zylinderachse. Dies hat den Vorteil, dass durch die Berandung des Zylinders der Gewinn bei niedrigen Elevationswinkeln so beeinflusst wird, dass der Elevationsbereich des Antennendiagramms eingestellt werden kann.The Height of Cylinder is chosen in the range less than half the operating wavelength so that the radiation characteristic in the area outside the cylinder axis, especially on the outer edge, a higher one Antenna gain g has as in the area of the cylinder axis. This has the advantage that by the border of the cylinder of the profit at low elevation angles is influenced so that the elevation range of the antenna pattern can be adjusted.
