Abstract

The non-reciprocal phase shifter of micro-strip construction has a winding (H) around an inner sleeve (R) of ferrite material, as in the main patent. This forms a dielectric support for the winding, which is a metal strip. These parts are enclosed by an outer sleeve (HU) of magnetic or non-magnetic dielectric material, to reduce losses. The outer sleeve has a metal layer (M) around the outside, which is electrically connected to the metal layer on the hole (I) through the interior of the inner sleeve.

Patentanspruch:Claim: Nichtreziproker, schaltbarer Phasenschieber auf Ferritbasis in Mikrostrip-Bauweise mit einer Ferrithülse als dielektrischem Träger und einer auf die Innenwandung dieser Ferrithülse ganzflächig aufgebrachten Metallschicht als Basisleiter der Mikrostrip-Struktur sowie einem in Form einer einlagigen Wicklung auf die Außenwandung der Ferrithülse aufgebrachten Streifenleiter, nach Patent 21 39 379, dadurch gekennzeichnet, daß die auf die Ferrithülse (R) aufgebrachte Wicklung (H) zusätzlich von einer weiteren Hülse (HÜ) umgeben ist, die aus magnetischem oder nicht-magnetischem dielektrischem Material besteht und auf der Außenseite (M) metallisiert und mit der Metallschicht der Innenbohrung (I) der inneren Ferrithülse (R) verbunden ist.Non-reciprocal, switchable phase shifter based on ferrite in microstrip design with a ferrite sleeve as a dielectric carrier and a metal layer applied over the entire surface of the inner wall of this ferrite sleeve as the base conductor of the microstrip structure and a strip conductor applied in the form of a single-layer winding to the outer wall of the ferrite sleeve, according to patent 21 39 379, characterized in that the winding (H ) applied to the ferrite sleeve (R) is additionally surrounded by a further sleeve (HÜ) made of magnetic or non-magnetic dielectric material and metallized on the outside (M) and with the metal layer of the inner bore (I) of the inner ferrite sleeve (R) is connected. Die Erfindung bezieht sich auf einen nichtreziproken, schaltbaren Phasenschieber auf Ferritbasis in Mikrostrip-Bauweise mit einer Ferrkhülse als dielektrischem Träger und einer auf die Innenwandung dieser Ferrithülse ganzflächig aufgebrachten Metallschicht als Basisleiter der Mikrostrip-Struktur sowie einem in Form einer einlagigen Wicklung auf die Außenwandung der Ferrithülse aufgebrachten Streifenleiter nach Patent 21 39 379.The invention relates to a non-reciprocal, switchable phase shifter based on ferrite in a microstrip design with a Ferrkhülse as a dielectric carrier and one on the inner wall of this Ferrite sleeve applied over the entire surface as a base conductor of the microstrip structure as well as an in Strip conductor according to the patent applied to the outer wall of the ferrite sleeve in the form of a single-layer winding 21 39 379. Dieser Phasenschieber arbeitet durchaus zufriedenstellend und ist sehr einfach herstellen. In manchen Anwendungsfällen werden jedoch noch höhere Anforderungen gestellt, wobei ein höherer Aufwand in Kauf genommen werden kann.This phase shifter works quite satisfactorily and is very easy to manufacture. In some However, even higher demands are placed on use cases, with a higher expense being accepted can be taken. Der vorliegenden Anmeldung liegt daher die Aufgabe zugrunde, den Phasenschieber gemäß Hauptpatent so auszugestalten, daß die Verluste verringert werden. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die auf die Ferrithülse aufgebrachte Wicklung zusätzlich von einer weiteren Hülse umgeben ist, die aus magnetischem oder nicht-magnetischem dielektrischem Material besteht und auf der Außenseite metallisiert und mit der Metallschicht der Innenbohrung der inneren Ferrithülse verbunden ist.The present application is therefore based on the object of the phase shifter according to the main patent so to design that the losses are reduced. According to the invention, this object is achieved by that the winding applied to the ferrite sleeve is additionally surrounded by a further sleeve which consists of magnetic or non-magnetic dielectric material and metallized on the outside and with the metal layer of the inner bore of the inner Ferrite sleeve is connected. Durch diese Anordnung wird eine zusätzliche Abschirmung erzielt. Außerdem werden die Verluste dadurch verringert, daß die Abstrahlung von der gekrümmten Wicklungsstruktur verringert wird.This arrangement provides additional shielding. Also, the losses reduced by reducing the radiation from the curved winding structure. Die Zeichnung stellt ein Ausführungsbeispiel dar.The drawing shows an exemplary embodiment. Die auf der Ferrithülse R aufgebrachte Wicklung H ist von einer Hülse umgeben, die aus magnetischem oder nicht-magnetischem dielektrischem Material bestehen kann, während die Außenseite M metallisiert ist. Die Wandstärke ha der Hülse HÜ richtet sich nach den Materialeigenschaften und hängt von der Breite w der Wicklung ab. Die Metallschicht auf der Außenseite M der Hülse ist mit der Metallschicht der Innenbohrung /derinneren Ferrithülse /{verbunden.The winding H applied to the ferrite sleeve R is surrounded by a sleeve , which can consist of magnetic or non-magnetic dielectric material, while the outside M is metallized. The wall thickness ha of the sleeve HÜ depends on the material properties and depends on the width w of the winding. The metal layer on the outside M of the sleeve is connected to the metal layer of the inner bore / the inner ferrite sleeve / {.
