An antenna array () with at least one dipole-type emitter arrangement (), wherein the at least one dipole-type emitter arrangement () comprises two pairs () of emitter halves (), which transmit and/or receive on two polarization planes () that are perpendicular to one another. The emitter halves () can be or are arranged on an emitter plane () at a distance from a reflector () and run parallel to said reflector. Two electrically conductive partial circumferential frames () are provided, which are disposed between the emitter plane () and the reflector () at a distance from one another, wherein the at least two electrically conductive partial circumferential frames () define one opening (). The at least two partial circumferential frames () are oriented parallel to the emitter plane (). Each of the two partial circumferential frames () comprises at least one gap (), which extends through the entire width of the partial circumferential frame (), so that each partial circumferential frame () comprises at least two ends.

Antenna array with at least one dipole-type emitter arrangement

The invention proposes a dipole radiator module, comprising a first and a second dipole radiator. The first dipole radiator comprises two first half-dipole components and two second half-dipole components, of which one is respectively perpendicular to one of the two first half-dipole components. On the respective at a right angle converging ends, at respective outer corner regions of the respective perpendicular to one another first and second half-dipole components, are disposed open areas with first legs, which are spaced apart and associated with each of the first and second half-dipole components, wherein the first legs exhibit a first length. Further comprised are two third half-dipole components, which form a first upper side of the first dipole emitter, and two fourth half-dipole components, of which one is respectively perpendicular to one of the two third half-dipole components, wherein on the respective at a right angle converging ends, at respective outer corner regions of the respective perpendicular to one another third and fourth half-dipole components, are disposed open areas with second legs, which are spaced apart and associated with each of the third and fourth half-dipole components, wherein the second legs exhibit a second length. The second dipole radiator [comprises] two fifth half-dipole components, which form a second underside of the second dipole radiator, as well as two sixth half-dipole components, of which one is respectively perpendicular to one of the two fifth half-dipole components, and wherein the respective at a right angle converging ends of respective outer corner regions of the respective perpendicular to one another fifth and sixth half-dipole components are conductively connected to one another. Further comprised are two seventh half-dipole components, as well as two eighth half-dipole components, of which one is respectively perpendicular to one of the two seventh half-dipole components, and wherein on the respective at a right angle converging ends, at respective outer corner regions of the respective perpendicular to one another seventh and eighth half-dipole components, are disposed open areas [with] third legs, which are spaced apart and associated with each of the seventh and eighth half-dipole components, wherein the third legs exhibit a third length.

Dipole beam module

A dipole-shaped antenna element arrangement comprises two pairs of radiator halves which are arranged so as to be rotated by 90&#xb0; to one another and are oriented in a radiator plane at a distance in front of a reflector and in parallel therewith. The radiator halves are arranged on a balancing and/or support arrangement. There is a passive beam-shaping frame which is arranged at a distance from the radiator halves towards the reflector. The passive beam-shaping frame has at the corners thereof a broadening of the peripheral frame web thereof, said broadening of the frame web extending in parallel with the radiator plane and/or transversely to the radiator plane.
