ABSTRACT:
A housing is provided for a radio device, such as a portable cellular telephone, in a housing arrangement which includes an integral electromagnetic shield. A thin conductive film is applied to an interior or exterior surface of one or more shell-type housing parts. This thin film may be applied during an injection molding process to form the shell-type parts. The shell-type parts are shaped to define a cavity for encasing electronic components of the radio device, and for securably receiving an associated circuit board. The thin film is disposed to extend over a supporting edge of the corresponding housing part so that circuit board grounding surfaces are in low-resistance contact with the shielding film. The film thereby provides the housing with an integrated shielding function against electromagnetic radiation.
