An antenna element is provided. The antenna element comprises: a support structure; a radiating structure arranged on or within the support structure, said radiating structure comprising: a radiating element having a resonant frequency inside an operating frequency band of the antenna element; and a filter connected to the radiating element and configured to filter out harmonics of the operating frequency band. An antenna system is also provided, which comprises a first antenna element according to the first aspect configured to radiate in a first operating frequency band, and a second antenna element configured to radiate in a second operating frequency band, wherein the second operating frequency band overlaps with harmonics of the first operating frequency band.

Integrated filtering for band rejection in an antenna element

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.

Apparatus, method and computer program for generating broadcast beams

The disclosure relates to a radio transceiving device, comprising: a multi-antenna array; a main transceiver coupled to the multi-antenna array, wherein the main transceiver is configured to beamform a first plurality of digital signals over a total transceiver bandwidth, wherein a part of the beamforming is processed in digital domain and another part of the beamforming is processed in analog domain; and an auxiliary transceiver coupled to the multi-antenna array, wherein the auxiliary transceiver is configured to beamform a second plurality of digital signals over a fraction of the total transceiver bandwidth, wherein the beamforming is processed in digital domain.
