  • Patent number: 4814782
    Abstract: An antenna having provision for mounting to a printed circuit board and method for making the antenna is described. The antenna includes a generally elongate, magnetically permeable core having a major axis and an insulating substrate affixed along an axis parallel to the major axis. The insulating substrate has a plurality of opposed pairs of spaced conductive runners positioned at generally regular intervals along the substrate normal to the major axis. A plurality of discrete capacitors are and perpendicular to secured between the opposed pairs of conductive runners. An electrically conductive split sleeve substantially surrounds the core and has pairs of opposed tabs on the edge portions in electrical connection with the opposed pairs of conductive runners. The sleeve further includes integral mounting tabs for securing the antenna assembly to the printed circuit board to establish electrical connection to the antenna without the use of wire leads.
