Abstract (en)
[origin: WO2014005691A1] The invention relates to an antenna system consisting of at least four horn antennas which support two orthogonal linear polarizations and have constrictions in both polarization planes. The fact that the horn antennas are constricted in the two polarization planes by symmetrical geometrical constrictions allows for a substantial increase in the bandwidth of the horn antennas, thus making it possible to service also wide transmission and reception bands or transmission and reception bands with widely spaced-apart frequencies, such as the Ka band. In order to be able to optimally operate the individual ridged horn antennas also in widely spread-apart service frequency bands, advantageously both the horn antennas and the constrictions are step-shaped. A suitable selection of the height and width of the steps of the horn antenna and the steps of the constrictions allows the horn antennas to be optimally adjusted to the service frequency bands according to the impedance.
Abstract (de)
Die Erfindung betrifft ein Antennensystem mit mindestens vier Hornstrahlern, die vollständig mit einem Dielektrikum gefüllt sind. Entsprechend den dielektrischen Eigenschaften der Füllung steigt dann die effektive Wellenlänge in den Hörnern und diese sind in der Lage sehr viel größere Bandbreiten zu unterstützen als dies ohne Füllung der Fall wäre. Dielektrische Füllungen führen zwar zu parasitären Verlusten durch das Dielektrikum, doch insbesondere bei sehr kleinen Hörnern für Anwendungen im Ka-Band bleiben diese Verluste vergleichsweise klein. Die Dielektrizitätszahl des Dielektrikums ist so gewählt, dass die dielektrisch gefüllten Hornstrahler im frequenzmäßig niedrigsten Nutzband des Antennensystems noch optimal betrieben werden können.
