Abstract

Gegenstand der Erfindung ist eine Einrichtung zum Verbessern der Entkopplung von wendelförmigen Sende- und/oder Empfangsantennen wenigstens eines Paares von Antennen mit gegensinniger Zirkularpolarisation, die auf einer elektrisch leitenden ebenen Reflektorwand senkrecht stehen. Die Einrichtung verbessert die Entkopplung bei solchen Antennenpaaren erheblich durch mindestens eine elektrisch leitende, zylindrische Trennwand, die durch die Mitte zwischen den beiden Antennen eines Antennenpaares, insbesondere zwischen einer Sende- und einer Empfangsan­ tenne, verläuft und senkrecht auf der Reflektorwand steht sowie elektrisch leitend mit dieser verbunden ist. The invention relates to a device for Improve the decoupling of helical transmit and / or receiving antennas of at least one pair of Antennas with circular polarization in opposite directions an electrically conductive flat reflector wall vertically stand. The device improves the decoupling such antenna pairs significantly by at least one electrically conductive, cylindrical partition wall through the Middle between the two antennas of a pair of antennas, in particular between a send and a receive threshing floor, runs and stands vertically on the reflector wall and is connected to it in an electrically conductive manner.
