A communication device including a housing which includes a front and a surrounding electrically conductive frame, the front including a dielectric cover, where the housing accommodates: a display covered by the cover; an electrically conductive chassis; and at least one substrate including at least one feeding element. Along at least a part of the frame and between the display and the substrate the chassis and the frame are separated from one another by a dielectric-filled intermediate space. Along the part of the frame and between the cover and the dielectric-filled intermediate space the display is separated from the frame by a gap. The dielectric-filled intermediate space together with the frame and the chassis form at least one waveguide structure extending between the substrate and the gap.
