摘要：
An antenna device for a portable radio communication device comprises a radiating element (10), a filter stage (20) connected to the radiating element, and an amplifier stage (30) connected to the filter stage and connectable to a receiver device for radio signals (40). By providing an amplifier stage that is not unconditionally stable, an antenna device having advantageous characteristics is achieved.
