Abstract: This disclosure presents an antenna device including one or more arrays of radiating elements, wherein each array may be an end-fire array. The antenna device comprises an array of N radiating elements (N>1) arranged on a common axis. Each radiating element is configured to radiate a radio wave in response to a RF signal fed to the respective radiating element. A reflector is arranged on the common axis to reflect the N radio waves into a main radiating direction. The antenna device comprises a feed structure to feed a RF signal to each radiating element. The RF signal at each radiating element has a respective phase difference relative to the RF signal at a first radiating element. The feed structure comprises one or more phase shifters, for one or more or all radiating elements, to set the phase difference of the RF signal at the respective radiating element.

Abstract: An antenna that is suitable for multiband operation. The antenna includes a plurality of first radiating elements configured to radiate in a first frequency band. The first radiating elements are arranged in a sparse mMIMO array. The antenna further includes a plurality of second radiating elements configured to radiate in a second frequency band lower than the first frequency band. The second radiating elements are arranged in an array at least partially overlapping with the sparse array. At least some of the second radiating elements are disposed in an area covered by the sparse mMIMO array.

Abstract: An antenna has a plurality of first radiating elements configured to radiate in a first frequency band and a plurality of second radiating elements configured to radiate in a second frequency band. The second frequency band at least partially overlaps the first frequency band. The first radiating elements are arranged along the longitudinal direction of the antenna in a first column, and the second radiating elements are arranged along the longitudinal direction of the antenna in a second column. The second column is separated from the first column along a lateral direction of the antenna. Further, feed points of each first radiating element are separated from feed points of each second radiating element along a bore sight direction of the antenna.

Abstract: The present invention provides a dual-polarized radiating element comprising a feeding arrangement and four dipole arms. The feeding arrangement comprises four slots, which extend from a periphery towards a center of the feeding arrangement and which are arranged at regular angular intervals forming a first angular arrangement. The four dipole arms extend outwards from the feeding arrangement and are arranged at regular angular intervals to form a second angular arrangement. The second angular arrangement of the four dipole arms is rotated with respect to the first angular arrangement of the four slots.
