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 element includes a reflector plate and a radiator comprising a balun device and a dipole device for operating in a first frequency band. The dipole device is connected to the reflector plate by the balun device. A distance from the dipole device to the reflector plate is more than ¼ of a wavelength at a central frequency of the first frequency band. The balun device comprises a short-circuit at a distance from the dipole device of 15 to 35 percent of said wavelength.

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.

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 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: An apparatus generates a first broadcast beam by feeding a first broadcast beam signal to a first set of dual polarized antenna elements at a first input for a first polarization and a second set of dual polarized antenna elements at a second input for a second polarization. The apparatus generates a second broadcast beam by feeding a second broadcast beam signal to a third set of dual polarized antenna elements at a first input for the first polarization and to a fourth set of dual polarized antenna elements at a second input for the second polarization.
