Circularly polarised microwave antenna
EP 0071069 A3
Abstract  translated from German
Bei einem aus einem Hohlleiterstrahler und zwei über einen Hybrid (12) angesteuerten, um 90° zueinander sen krecht zur Achse des Hohlleiterstrahlers angeordneten Erre gerstrahlern (14) bestehenden Mikrowellenantenne (1) für rechts- und linkszirkular polarisierte elektromagnetische Wellen sind zum Zweck der Erzielung einer hochgenauen Phasendifferenz der Polarisationsanteile mit einfachen und kostensparenden, möglichst für Mengenherstellung geeig neten Mitteln die Erregerstrahler (14), der Hybrid (12), sowie deren Verbindungsleitungen (13) in Drucktechnik auf einem Substrat (7) ausgeführt, dessen die Erregerstrahler (14) tragender Teil transversal im Hohlleiterstrahler angeordnet ist. In a controlled from a waveguide radiator and two hybrid (12) Krecht 90 ° to each other sen to the axis of the waveguide radiator arranged Erre gerstrahlern (14) existing microwave antenna (1) for right and left circularly polarized electromagnetic waves are for the purpose of obtaining a highly accurate phase difference of the polarization components with simple and cost effective as possible for quantity production appro Neten means the exciter lamp (14) Hybrid (12), and their connecting lines (13) running in printing technology on a substrate (7), the excitation lamp (14) bearing part transversely in the waveguide antenna is located.
