Abstract
A portable radio device is shown with an outer cover (202) and a radiating antenna element (206, 207, 208, 226, 227) inside the outer cover (202). At a location corresponding to the location of the radiating antenna element (206, 207, 208, 226, 227), there is thermoplastic material (203, 215, 217, 219) the loss tangent value of which is less than 0.005. The outer cover (202) has, on the outer surface thereof and at a location corresponding to the location of the radiating antenna element (206, 207, 208, 226, 227), a coating (204, 209, 216, 218, 220) that is one of: diamond coating, diamond-like coating, diamond-based nanocomposite coating.
