The invention relates to frame structures, particularly to mobile stations and other small-sized portable devices operating at high frequencies. The frame structure according to the invention is formed by extrusion, whereby the fixing means required for fastening components are formed into it during the extrusion. Such fixing means are preferably pin-like projections which can be compressed to a rivet fixing the component. Such fixing means can also be strip-like fixing edges which are bent over the component edges. With such fixing means it is possible to form at the same time both a mechanical fixing and a good electrical contact between the component and the frame structure. During the extrusion it is also possible to fasten to the frame structure parts made of other materials, such as fixing means of other types or other components, such as antennas.
