Description

Hochfrequenzanordnung Antennen werden bekanntlich so ausgebildet und an die Speiseleitung angeschlossen, daß sie für die Betriebsfrequenz am besten wirksam und an die Speiseleitung angepaßt sind. Bei Übertragung eines ])reiten Frequenzbandes läßt sich diese Bedingung grundsätzlich nur für eine Frequenz, z. B. die mittlere Frequenz des Bandes, erfüllen. Um eine angenähert gleichmäßige Wirksamkeit der Antenne in einem breiten Frequenzband zu erzielen, sind bereits verschikedene Maßnahmen bekannt, wie die Anwendung eines großen Querschnittes des Antennenleiters oder die Einschaltung zusätzlicher Kreise am Ende der Speiseleitung. Auch die Zwischenschaltung mehrerer geeignet b.emes euer Traneformutionisleitungen. ist vorgeschlagen worden. Diese Maßnahmen sind nicht immer ohne weiteres anwendbar, häufig schwierig durchzuführen oder für sich allein noch nicht genügend wirksam.As is known, high-frequency arrangement antennas are designed and constructed in this way connected to the feed line so that it is most effective for the operating frequency and are adapted to the feed line. When transmitting a]) riding frequency band can this condition in principle only for one frequency, z. B. the middle one Frequency of the band, meet. To achieve an approximately uniform effectiveness of the antenna Achieving in a broad frequency band are already different measures known as the use of a large cross-section of the antenna conductor or the Activation of additional circuits at the end of the feed line. Also the interposition several suitable b.emes your Traneformutionisleitung. has been suggested. These measures are not always readily applicable and often difficult to implement or not yet sufficiently effective on their own.

Die Erfindung gibt bei einer Hochfrequenzanordnung mit einer Antenne, in die der Innenleiter einer koaxialen Hochfrequenzleitung übergeht, einen neuen Weg zur Erzielung einer Breitb:andwirkung an, der dadurch gekennzeichnet ist, daß an den in die Antenne übergehenden Innenleiter mehrere an sich bekannte, einen Kurzschluß mach außen oder eine Sperrung in der Längsrichtung bewirkende, in Resonanz befindliche Leiter (Stäbchen; oder Töpfe oder Gegengewichtsplatten:) derart angeschlossen,sind, daß eine Bandfilterwirkung der Antenne erzielt wird.The invention gives in a high-frequency arrangement with an antenna, into which the inner conductor of a coaxial high-frequency line merges, a new one Way to achieve a broad-based effect, which is characterized in that several known per se on the inner conductor passing into the antenna, a short circuit make outside or a blocking in the longitudinal direction, which are in resonance Ladder (chopsticks; or pots or counterweight plates :) such are connected, that a band filter effect of the antenna is achieved.

Derartige Stäbchen, Töpfe oder Gegengewichtsplatten wurden bisher nur an den Außenleiter der koaxialen Speiseleitung bzw. an das mit diesem. Außenleiter verbundene Tragwerk der Antenne angeschlossen, um die störenden Mantelwellenströme zu beseitigen. Durch Anschluß mehrerer derartiger Leiter an den in die Antenne . übergehenden Innenleiter (unter geeigneter verschiedener Abstimmung und/oder Anschaltung in verschiedenen Abständen) läßt sich jedoch erfindungsgemäß eine Bandfilterwirkung der Antenne und damit eine gleichmäßige Wirksamkeit der Antenne in einem breiten Frequenzbereich erzielen.Such chopsticks, pots or counterweight plates have been used so far only to the outer conductor of the coaxial feed line or to the one with this. Outer conductor connected structure of the antenna connected to the disruptive standing wave currents to eliminate. By connecting several such conductors to the in the antenna. passing inner conductor (with suitable different coordination and / or connection at different distances), however, according to the invention, a band filter effect can be achieved the antenna and thus a uniform effectiveness of the antenna in a wide area Achieve frequency range.
