  • Patent number: 11355836
    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 t1, where t1??min/3, wherein ?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.

  • Patent number: 10193206
    Abstract: The present invention relates to a microwave signal transition component (1) having a first signal conductor side (2) and a second signal conductor side (3). The signal transition component (1) is arranged for transfer of microwave signals from the first signal conductor side (2) to the second signal conductor side (3). The transfer component (1) comprises at least one, at least partly circumferentially running, electrically conducting frame (4), a dielectric filling (5) positioned at least partly within said conducting frame (4), at least one filling aperture (6; 6a, 6b) miming through the dielectric filling, and, for each filling aperture (6; 6a, 6b), an electrically conducting connection (7; 7a, 7b) that at least partly is positioned within said filling aperture (6; 6a, 6b). The present invention also relates to a method for manufacturing a microwave signal transition component according to the above.

  • Patent number: 5990568
    Abstract: A yawing system for a wind turbine is provided. The system adjusts the wind turbine into a required wind direction against the wind by turning the turbine about a yawing axle (14) and counteracts periodic vibrations in a nacelle of the turbine as it turns around the yawing axle from being transmitted as pulsating moments to a tower structure. At least one hydraulic motor (34) turns the nacelle (12) about the yawing axle (14). A controllable throttle valve (50) is disposed in a parallel line to the hydraulic motor (34). A regulator (30) is capable of changing an opening diameter of said throttle valve (50) in accordance with a position of the nacelle in relation to the wind direction such that the periodic vibrations are utilized for turning the nacelle and correcting for changes in the wind direction during operation by a successive movement of the nacelle in small steps in the required wind direction during each periodic vibration around the yawing axle and at the same time as the nacelle is dampened.
