An antenna device for transmitting/receiving RF waves to be arranged in a radio communication device, comprising: a carrier (10) having first and second surfaces carrying a radiating structure (20) on the first surface; a feed portion (25) being connectable to transceiver circuits of the radio communication device and being arranged on the carrier (10) and forming a part of the radiating structure (20); and a ground plane means. The carrier has, in a first plane essentially perpendicular to the first surface, a cross section where the first surface exhibits at least a first curved portion (12). Further, the carrier has, in a second plane essentially perpendicular to the first plane and essentially perpendicular to the first surface, a cross section where the first surface exhibits at least a second curved portion (11, 13). Moreover, at least two curved portions meet. Further a method for manufacturing an antenna device is disclosed. In the method, at least a part of the carrier is formed by means of a die having essentially the same shape as a portion of an inner wall of a housing of the radio communication device. Also a hand portable radio communication device, including an antenna device is disclosed.
