Abstract: The disclosure relates to a patch antenna that comprises at least two different arrays of conductive patches arranged on one side of a dielectric substrate. Each of the at least two arrays of conductive patches supports a different frequency band. Moreover, each of the at least two arrays of conductive patches is provided with separated feeding. Additionally, each conductive patch of one or more of the at least two arrays of conductive patches (e.g., those intended for low frequencies) is implemented as a combination two conductive sub-patches separated by a gap, which allows one to define an appropriate operating frequency bandwidth. This configuration of the patch antenna also allows one to individually design the size of each conductive patch, as well as an inter-patch spacing for each of the frequency bands. In one embodiment, the patch antenna is suitable for integration into a display structure of a UE.

Abstract: A display panel (1) transparent to electromagnetic signals and comprising a plurality of light emitting diode clusters (2), each pair of adjacent light emitting diode clusters (2) being separated by a dielectric gap (3a, 3b), and a plurality of first interconnection arrangements (4) configured to interconnect at least two adjacent light emitting diode clusters (2). The first interconnection arrangements (4) and at least two of the gaps (3a) are configured to form at least one two-dimensional slot structure (5) comprising a first section (5a) and a second section (5b). Each section (5a, 5b) is formed by a gap (3a) and has a length (L1, L2) which is at least twice as long as a corresponding length (L3, L4) of one light emitting diode cluster (2). The first interconnection arrangements (4) are configured such that at least one slot structure (5) is transparent to electromagnetic signals in a millimeter-wave frequency band.
