Abstract:
A flex antenna comprising:(a) a conductive mounting element having a conductive connecting/disconnecting structure for connecting and disconnecting the flex antenna to and from a mounting connector;(b) a piece of flex conductor having a first end and a second end, the first end being attached to the conductive mounting element;(c) a conductive coil support having a first end attached to the second end of the piece of flex conductor, and a second end;(d) an insulative rod having a first end attached to the second end of the conductive coil support, and a second end;(e) an antenna coil wound about the insulative rod and having a free end located near the second end of the insulative rod, and a connected end located near the first end of the insulative rod and electrically attached to the conductive coil support; and(f) an insulative sheath disposed on the entire flex antenna except an exposed portion of the conductive connecting/disconnecting structure, wherein the sheath includes a cylindrical first portion of a first diameter disposed around the conductive coil support, the insulative rod, and the antenna coil, and a second portion of diameter which gradually decreases from the first diameter to a second diameter and then increases to a third diameter, the second diameter being generally at a midpoint of the flex conductor to confine flexing thereof generally to the midpoint of the flex conductor.
