1. An assembly for an antenna operating in a slot mode, wherein the assembly comprises
at least one printed circuit board of an electronic wristwatch-like device,
a conductive body arranged at a distance from said at least one printed circuit board and defining a slot mode antenna between them, wherein the conductive body is a bezel being a part of a housing encompassing the electronic wristwatch-like device,
said antenna having two end connection points at which said bezel 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 is 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.
