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≤λmin/3, wherein λmin 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.
