Definitions
- the invention relates to an antenna with at least two powered radiators according to the preamble of claim 1.
- radiators with at least two, ie with a plurality of supplied radiators it is known that it is important to achieve the highest possible decoupling between the different radiators.
- a high level of decoupling between the radiators of one polarization and the radiators of the other polarization orthogonal to it is desirable.
- Such arrays can consist, for example, of several elements in the form of dipoles, slots or planar emitter elements, such as those from EP 0 685 900 AI or from the prior publication "Antennas", Part 2, Bibliographical Institute in Mannheim / Vienna / Zurich, 1970, pages 47 to 50 are known.
- radiators are usually arranged in front of a reflector. It proves to be disadvantageous that the decoupling, which is good per se, in particular between radiators with orthogonal polarizations, is impaired by the arrangement as an array, in particular by the influences of the reflector.
- decoupling devices in the form of strips or crosses between the radiators, in particular when the strips are used, these are arranged along the connecting line of two antenna devices of an antenna array which are offset from one another.
- these strips are not arranged transversely to the connecting direction of two antenna arrangements, but parallel to the connecting line between two adjacent antenna devices.
- Decoupling elements propose passive strip arrangements that are staggered between two Antenna devices arranged in the manner of an antenna array are provided centrally between them in the direction transverse to the mounting direction of the radiators, or else parallel to the mounting direction and are arranged laterally from the radiators.
- this arrangement already corresponds to the previously published US Pat. No. 3,541,559, which also proposes to arrange the individual decoupling elements laterally from the individual antennas in the manner of a frame.
- GB 2 171 257 A also discloses an antenna array which has a plurality of dipoles arranged vertically one above the other, a projecting element being arranged above two dipoles arranged one above the other, which element is intended to improve the decoupling between the dipoles.
- this antenna array which is known from this publication, is constructed using stripline technology.
- the object of the present invention is to provide a further improved possibility for decoupling the various radiators in antennas with at least two fed radiators, in particular in antenna arrays and in particular in dual-polarized antenna arrays.
- the decoupling elements which are preferably rod-shaped, are aligned with a component in the direction of propagation of the electromagnetic waves, that is to say in particular perpendicular to the plane of the reflector plate, at least these components representing a larger value than a component perpendicular to them. If the decoupling elements are in the form of a rod, this means with others
- the system according to the invention - and this is particularly surprising - has decisive advantages, particularly in the case of dual-polarized antennas, which in particular comprise at least one cross dipole or at least one dipole square. In contrast, those from the
- GB 2 171 257 A known coupling elements only a dipole arrangement of a polarization, which are also adjacent.
- two orthogonal polarizations are preferably affected in each case, in which no vertically adjacent radiators, which could be decoupled, are provided.
- Another difference from the prior art is that dual-polarized antennas use two separate inputs, between which a decoupling (or isolation) must be measurable, while with the improved decoupling, such a decoupling cannot be measured in a deeper arrangement with only one polarization is (since there is only one input).
- the decoupling elements according to the invention are preferably rod-shaped and / or peg-shaped.
- the decoupling elements according to the invention can be arranged, for example, between two radiators, for example between two or more vertically polarized or horizontally polarized radiators, in each case in the region of the connecting line of these radiators.
- the decoupling elements according to the invention which are preferably perpendicular to the reflector plate, can be arranged in the immediate region between the individual dipole halves, for example in a plan view of an bisector of a cross dipole arrangement.
- one or more of the inventive Coupling elements can be arranged, for example, in the case of a dipole square within the dipole square, and in turn here preferably on an bisector of the dipole square.
- the rod-shaped decoupling elements according to the invention extend, as stated, with their greatest longitudinal extension or component in the direction of propagation of the magnetic waves and / or perpendicular to the reflector plane.
- the decoupling elements can have a uniform cross-section or a wide variety of cross-sectional shapes, for example with a round or with regular or irregular n-polygonal, for example square or hexagonal cross-section, etc.
- the cross section can also vary over the length of the decoupling elements according to the invention. It is also possible that the cross-sectional areas are not rotationally symmetrical, but, for example, have different longitudinal extensions along two intersecting axes that are perpendicular to one another and run parallel to the reflector surface.
- decoupling elements according to the invention are provided, in particular also at their end opposite the reflector plate, with formations or attachments which also extend transversely to the vertical extension component of the decoupling elements and thus transversely to the direction of propagation of the electromagnetic waves and / or parallel to the level of the reflector sheet can extend.
