Abstract
The present disclosure relates to dipole antennas, for example, to antenna array radiating elements in an Active Antenna System (AAS). A radiating element of this disclosure comprises a substrate and at least two dipole arms formed on the substrate. In this regard, each dipole arm comprises at least two current paths with different electrical length. Furthermore, at least one outer area up to the edge of the substrate is bent. Moreover, at least one current path of the at least two current paths extends to the bent outer area of the substrate.

A radiating element comprising:
- a substrate, and
- at least two dipole arms formed on the substrate,
- wherein each dipole arm comprises at least two current paths with different electrical length,
- wherein at least one outer area up to the edge of the substrate is bent, and
- wherein at least one current path of the at least two current paths extends to the bent outer area of the substrate.
A dual polarized antenna comprising:
- a reflector, and
- one or more radiating elements,
- wherein the one or more radiating elements comprise a substrate, and at least two dipole arms formed on the substrate, wherein each dipole arm comprises at least two current paths with different electrical length, wherein at least one outer area up to the edge of the substrate is bent, and wherein at least one current path of the at least two current paths extends to the bent outer area of the substrate,
- wherein each of the one or more radiating elements is arranged on the reflector at a predefined distance to the reflector.
A method for forming a radiating module, comprising:
- providing a substrate,
- forming at least two dipole arms on the substrate such that each dipole arm comprises at least two current paths with different electrical length, and
