Abstract: A dual polarity antenna including: a first radiator for radiating or for receiving a first radio-frequency (RF) wave having a first linear polarisation, and a second radiator for radiating or for receiving a second RF wave having a second linear polarisation orthogonal to the first linear polarisation. The first radiator includes one or more electrically conductive parts and the second radiator is provided by one or more slots in the one or more electrically conductive parts. An antenna column array may be densified and the size of the array columns may be reduced by locating and/or embedding the second radiator in the first radiator.

Abstract: An antenna element for a multi-band antenna device includes a dielectric body provided with one or more metal layers. The dielectric body includes a base plate and one or more wall elements arranged on the base plate. One or more first radiating elements and one or more second radiating elements are arranged on the base plate, and are configured to radiate in a first and a second frequency band, respectively. A first feeding network is connected to the first radiating elements and a second feeding network is connected to the second radiating elements, for operating the first and second radiating elements as a first and second antenna array, respectively. 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.
