Abstract
The invention relates to an antenna construction for a double-ended antenna circuit. The antenna construction comprises a conductive ground place () on a first surface, a transmission line () on at least one second surface, connected to the ground plane () through a fold () in the edge of the antenna construction, so that the fold acts as a primary source of a magnetic field, an insulation layer () arranged between the first and the second surfaces, and an electronic component (), in which there is a double-ended antenna connector, connected to the antenna construction. According to the invention, the electronic component () is attached to the second surface of the antenna construction and connected from the first antenna terminal to the transmission line () and from the second terminal to either a second transmission line () or the fold ().
