Abstract: The present disclosure relates to an antenna arrangement including a first antenna configured to operate within a first frequency band and a second antenna configured to operate within a second frequency band. The first frequency band is higher than the second frequency band. Further, the second antenna is at least partly arranged within an illumination-field of the first antenna. Furthermore, the second antenna includes a dipole structure segmented into a plurality of electrically conductive sections, wherein each electrically conductive section is coupled to an adjacent electrically conductive section by a reactive load section.

Abstract: The present disclosure relates to an antenna array including an integral antenna element structure mounted on a substrate. The integral antenna element structure includes a first set of antenna elements and a second set of antenna elements. Each antenna element including a first body and an adjacent second body. The second body is branched into a first leg and a second leg, wherein a transition pin forms an integral part with said first leg. The first set, and second sets of antenna elements are arranged such that the first body and the second body of each adjacent antenna element form a common tapered structure.
