Abstract: The present disclosure relates to a waveguide gasket arrangement (1, 1', 1'') arranged for electrically sealing a waveguide interface (2) between a first waveguide end (3) and a second waveguide end (4). The waveguide gasket arrangement (1, 1', 1'') comprises a carrier arrangement (5, 5', 5'') where a carrier aperture (6; 6a, 6b) is formed in the mounted carrier arrangement (5, 5', 5''). The waveguide gasket arrangement (1, 1', 1'') further comprises an electrically conducting flexible ribbon arrangement (7) that comprises at least one plurality of electrically conducting members (8a, 8b) forming a coherent common structure. The ribbon arrangement (7) is mounted to a carrier aperture edge (11; 11a, 11b) that circumvents the carrier aperture (6; 6a, 6b) such that for each plurality of electrically conducting members (8a, 8b), a first plurality of electrically conducting members (8a) is adapted to extend towards the first waveguide end (3) and a second plurality of electrically conducting members (8b) is adapted to extend towards the second waveguide end (4).

Abstract: The present disclosure relates to a waveguide gasket arrangement (1, 1') arranged for electrically sealing a waveguide interface (2) between a first waveguide end (3) and a second waveguide end (4), where the waveguide gasket arrangement (1, 1') comprises a first plurality of electrically conducting members (5) connected to a first common structure (6) along a first circumference (7).The waveguide gasket arrangement (1) further comprises a second plurality of electrically conducting members (8) connected to a second common structure (9) along a second circumference (10). For each one of the first plurality of electrically conducting members (5) and the second plurality of electrically conducting members (5) there is: - a corresponding first sub-plurality of electrically conducting members (11, 12) which are intended to contact a waveguide end (3, 4), and - a second sub-plurality of electrically conducting members (13, 14) which are intended to contact a corresponding intermediate electrically conducting structure (15; 24, 25) that is positioned between the first plurality of electrically conducting members (5) and the second plurality of electrically conducting members (8).

Abstract: There is provided a combined antenna and radome arrangement. The combined antenna and radome arrangement comprises an advanced antenna system (AAS). The AAS comprises antenna elements and is configured for communication in a frequency range of 2.5 GHz to 10 GHz. The combined antenna and radome arrangement further comprises a radome. The radome has a first layer sandwiched between two second layers. The two second layers are of a second dielectric material. The first layer is of a first dielectric material and has a thickness t 1 , where t 1 ≤ λ min /3, wherein λ min is the wavelength of the highest frequency in the frequency range of the AAS. The radome is placed in front of the AAS such that the radome forms a cover for the AAS.
