Patent ID: 7340286

Claim:
An outer cover structure for a radio device, comprising a conductive planar component ( 230 ; 330 ; 430 ) and a dielectric planar component ( 240 ; 340 ; 440 ), the conductive planar component extending outside the dielectric planar component, which radio device has a planar antenna, a radiating element of which said conductive planar component is, wherein: the dielectric component comprises a first part ( 241 ; 341 ; 441 ) and a second part, which are integrally joined to each other, an upper surface of the first part being a part of an upper surface of the outer cover structure, and the second part ( 242 ; 342 ; 442 ), being located under the conductive component against its lower surface, and on lower surface of the second part of the dielectric component there is a conductive element ( 220 ; 320 ; 420 ), when connected to the radio device, together with the conductive component of the cover and the ground plane of the planar antenna, forms a resonator that oscillates on at least one operating band of the radio device.
