Abstract
There is provided a helical antenna structure, which exhibits minimal influence from contact with a human body in a mobile terminal. In the helical antenna structure, a cap protrudes from an upper end of the mobile terminal, and a winding coil is formed within the cap, which is spaced from an outer surface of the cap substantially the same distance from a bottom part of the cap to a top part of the cap.

3. A helical antenna structure for a mobile terminal, comprising:
-
a cap protruding from an upper end of the mobile terminal; and
a winding coil disposed within the cap and formed into a cone shape with a diameter decreased by a predetermined value at every turn from a bottom part to a top part of the cap so as to be spaced from an outer surface of the cap substantially the same distance from the bottom part of the cap to the top part of the cap.

4. A helical antenna structure for a mobile terminal comprising:
-
a substantially conical shaped cap protruding from the terminal; and
a substantially conical shaped coil disposed in said cap;
wherein a distance between an outer surface of the cap and the coil remains substantially the same from a bottom end of the cap and coil adjacent the terminal to a top end of the cap and coil remote from the terminal.
