Abstract
An antenna device for transmitting and receiving RF waves in at least a first frequency band and adapted to be arranged in a radio communication device. The antenna device comprises a support structure (26), at least one radiating antenna portion (27) carried by the support structure, a circuit carried by the support structure for processing analogue RF signals tapped from or fed to the radiating antenna portion, and coupling means arranged for connecting the circuit to the radio communication device. A radiation shielding device (28) of an electrically conductive material surrounds the circuit at least partially, and the shielding device (28) is functionally integrated with the radiating antenna portion (27) and forms an actively radiating part thereof.
