The invention concerns an assembly for an antenna operating in a slot mode. It is also directed to an electronic wristwatch-like device comprising such antennas. The antenna assembly comprises at least one circuit board of an electronic device, a conductive body arranged at a distance from said at least one circuit board and defining a slot between them, at least one feed element for coupling an electromagnetic signal between said conductive body and said circuit board. A length of the slot is defined between two points at which said conductive body is connected to a ground plane of said at least one circuit board.
An assembly for an antenna operating in a slot mode, wherein the assembly comprises at least one printed circuit board of an electronic device, a conductive body arranged at a distance from said at least one printed circuit board and defining a slot mode antenna between them, said antenna having two end connection points at which said conductive body is connected to a ground plane of said at least one circuit board, and between said connection points at the edge of one of said at least one printed circuit board at least one feed element for coupling an electromagnetic signal between said slot mode antenna and said circuit board, and wherein the effective width and/or length of the slot mode antenna is at least partially defined by a conductive rim structure running at least in part along the perimeter of said one printed circuit board and attached to the edge of said board.
An electronic wristwatch-like device comprising a housing, at least one printed circuit board inside said housing, a conductive bezel arranged at a distance from said printed circuit board as part of said housing and defining a slot between them, wherein the slot comprises an antenna operating in a slot mode having two end connecting points at which said bezel is connected to a ground plane of said at least one printed circuit board, and between said connection points at the edge of one of said at least one printed circuit board at least one feed element for coupling an electromagnetic signal between said slot mode antenna and said circuit board, and wherein said wristwatch-like device further comprises a conductive rim structure running at least in part along the perimeter of said one printed circuit board and attached to the edge of said board, with which the effective width and/or length of the slot mode antenna at least partially is defined.
