Abstract

Es wird eine planare Array-Antenne in Streifenleiter-­ Technik vorgeschlagen, die insbesondere zum Empfang von Satelliten-Rundfunksignalen im X-Band geeignet ist. Der mechanische Aufbau besteht aus einer ersten Substrat­ platte (10) als Träger für Antennenelemente (11) und einer zweiten Substratplatte (18) als Träger für die Koppler und die Signalweiterverarbeitung. Beide Substratplatten sind durch eine Metallplatte (13) miteinander verbunden, deren Dicke (d) der halben Betriebswellenlänge entspricht. Die elektrische Verbindung zwischen den Antennenelementen auf der Antennenvorderseite und den Kopplern auf der Antennenrückseite stellen koaxiale Leiterstücke her, die isoliert durch Bohrungen (14) in der Metallplatte geführt werden. In einer weiteren Ausführungsform der erfindungs­ gemäßen Array-Antenne mit drei Substratplatten und zwei Metallplatten ist auch der Empfang zirkular polarisierter Signale möglich. A planar array antenna in stripline Technique proposed, especially for reception of satellite broadcast signals in the X-band is suitable. The mechanical structure consists of a first substrate plate (10) as a carrier for antenna elements (11) and one second substrate plate (18) as a carrier for the couplers and signal processing. Both substrate plates are connected to each other by a metal plate (13), the Thickness (d) corresponds to half the operating wavelength. The electrical connection between the antenna elements on the front of the antenna and the couplers on the Rear of antenna produce coaxial conductor pieces that insulated through holes (14) in the metal plate will. In a further embodiment of the invention modern array antenna with three substrate plates and two Metal plates are also circularly polarized Signals possible.
