Description

Die Erfindung betrifft eine Mikrowellen-Gruppenantenne nach dem Oberbegriff de. Anspruchs 1.The invention relates to a microwave array antenna according to the preamble de. Claim 1.

Aus der DE-OS 24 18 506 sind Mikrowellen-Streifenleitungsantennen bekannt mit stählenden ElementenFrom DE-OS 24 18 506 microwave stripline antennas are known with steel elements

JO von etwa der Länge λ/2 auf einem dielektrischen Träger. Es ist auch bekannt, daß Strahlergruppen reihengespeist werden können, vgL z. B. R. C Hansen, Microwave Scanning Antennas, III, 1966, Academic Press New-York und London, Seiten 5—9. JO of about the length λ / 2 on a dielectric support. It is also known that groups of radiators can be fed in rows, vgL z. BR C Hansen, Microwave Scanning Antennas, III, 1966, Academic Press New-York and London, pp. 5-9.

Aufgabe der Erfindung ist es, bei Mikrowellen-Antennen der eingangs genannten Art ehien weiteren Freiheitsgrad im Entwarf zu schaffen.The object of the invention is to provide additional microwave antennas of the type mentioned at the beginning To create a degree of freedom in the design.

Die Lösung dieser Aufgabe der Erfindung ist dem kennzeichnenden Teil des Patentanspruchs 1 entnehmbar. The solution to this object of the invention can be found in the characterizing part of claim 1.

' Die Unteransprüche beinhalten vorteilhafte Weiterbildungen der Erfindung.The subclaims contain advantageous developments the invention.

Die Figur zeigt ein vorteilhaftes Ausführungsbeispie! der Erfindung. Auf einem dielektrischen Träger 3 mit einer Grundmetallisierung sind die strahlenden Elemente I1, I3 ... 1" von je etwa der Länge λ/2 in Reihe angeordnet. Die strahlenden Elemente der Strahlergruppe an den Enden sind nicht mit der Grundmetallisierung leitend verbunden. Die Speisung 2 erfoigt von unten durch den Träger an einem Ende eines beliebigen strahlenden Elements. Diese sind zur Variierung der Aperturbelegung unterschiedlich breitThe figure shows an advantageous Ausführungsbeispie! the invention. On a dielectric substrate 3 with a base metallization are the radiating elements I 1, I 3 ... 1 ", each about the length of λ / 2 are arranged in series. The radiating elements of the antenna array at the ends are not conductively connected to the base metallization. The feed 2 takes place from below through the carrier at one end of any radiating element, which are of different widths in order to vary the aperture coverage

Die Elemente I1,13... l"sind über Verbindungsleitungen I2, I4 ... l"-' von ebenfalls etwa der Länge λ/2 galvanisch gekoppelt Die Verbindungsleitungen I2, I4, ... \"-' sind unterschiedlich breit gewählt Dadurch ergibt sich ein zusätzlicher Freiheitsgrad in der Aperturbelegung und in der Impedanzanpassung.The elements I 1 , 1 3 ... l "are galvanically coupled via connecting lines I 2 , I 4 ... l" - 'also of approximately the length λ / 2. The connecting lines I 2 , I 4 , ... \ " - ' are chosen to be of different widths. This results in an additional degree of freedom in the aperture allocation and in the impedance matching.

In Weiterbildung der Erfindung weichen zur Erzielung einer größeren Bandbreite die einzelnen strahlenden Elemente und Verbindungsleitungen jeweils geringfügig verschieden von der Länge A/2 ab.In a further development of the invention, the individual radiating signals give way in order to achieve a larger bandwidth Elements and connecting lines each slightly different from the length A / 2.
