1. An antenna element for a multi-band antenna device, the antenna element comprising:
a dielectric body provided with one or more metal layers, the dielectric body comprising a base plate and one or more wall elements arranged on the base plate;
one or more first radiating elements arranged on the base plate, each of the one or more first radiating elements being configured to radiate in a first frequency band;
one or more second radiating elements arranged on the base plate, each of the one or more second radiating elements being configured to radiate in a second frequency band;
a first feeding network connected to the one or more first radiating elements, for operating the one or more first radiating elements as a first antenna array; and
a second feeding network connected to the one or more second radiating elements, for operating the one or more second radiating elements as a second antenna array;
wherein
the first feeding network is provided, at least partly, as a metal layer of the one or more metal layers on the one or more wall elements,
the one or more wall elements comprise an outer wall element, which extends along edges of the base plate,
a part of the first feeding network is provided as a metal layer of the one or more metal layers on the outer wall element,
the one or more wall elements further comprise one or more inner wall elements, each of the one or more inner wall elements connecting the outer wall element to one of the one or more first radiating elements, and
a further part of the first feeding network is provided as a metal layer of the one or more metal layers on the one or more inner wall elements.
