Abstract

The invention relates to frame and antenna structures of mobile stations, particularly to an antenna structure inside the cover of a mobile station. In the structure according to the invention the radiator of the antenna structure and the frame structure form an integral body. The radiator is formed already during the frame structure manufacturing step as a projection of the frame structure, or the radiator is partly cut out from the frame structure and bent into the desired final shape. The material and the manufacturing method of the frame structure according to the invention can be selected according to the requirements of the application in question, and the invention is not limited to any particular material or manufacturing method. Preferably the material of the structure according to the invention is a metal or a metal alloy, for instance aluminium or an aluminium alloy. The structure according to the invention can also be made of plastic and other dielectrics, if the radiator is coated with an electrically conducting layer in order to obtain the electrical function. The structure according to the invention can be advantageously formed e.g. by extrusion or casting, or by some other corresponding technique.
