| Zusammenfassung: | The radiator has an antenna element and a waveguide (100) for displacing phase of the antenna element, where the waveguide includes a liquid crystal-filled cavity (110). The antenna element is attached on a front side of the waveguide that includes a counter-sunk inner pressure compensation device (150) for compensating an inner pressure in the liquid crystal-filled cavity. The inner pressure compensation device is arranged in the waveguide, and the antenna element includes a metallization applied on the waveguide. Independent claims are also included for the following: (1) a method for manufacturing an antenna radiator (2) a method for manufacturing an antenna radiator arrangement.
Es wird ein Antennenstrahler bereitgestellt. Der Antennenstrahler umfasst ein Antennenelement (530) und einen Hohlleiter (560) zum Verschieben der Phase des Antennenelements. Der Hohlleiter umfasst eine flüssigkristallgefüllte Kavität (570). Das Antennenelement ist auf einer Stirnseite (562) des Hohlleiters angebracht. |
