ABSTRACT:
An antenna for coupling to a printed circuit board comprises a ferrite rod and an electrically conductive coil having at least one turn extending around the core. The ends of the coil form the antenna's leads and are bent to retain the core therebetween. The coil is also bent to form a protrusion which extends away from the core. The antenna's leads and the protrusion may then be coupled to a printed circuit board to secure the antenna.
