An extended range coil for an inductance-capacitance tuned circuit and a method for its manufacture. The extended range coil comprises a wire-wound planar spiral portion, having a circumference, and a wire-wound wall portion joined to the wire-wound planar spiral portion and extending outward from the circumference thereof. An extended range coil according to the present invention may use a continuous length of wire for winding the wire-wound planar spiral portion and the wire-wound wall portion.
