  • Publication number: 20030020660
    Abstract: In a helical antenna for use in a portable communication terminal containing a radio unit which transmits and receives a radio signal, an antenna element is connectable to the radio unit, and contains a bottom portion formed into a helical portion and a top portion formed into a linear portion, the linear portion being positioned along a screw axis of the helical portion. A cap houses the antenna element if the cap covers the antenna element from a top end of the antenna element. A position portion is provided in the cap and positions the linear portion of the antenna element along the screw axis of the helical portion. By virtue of this structure, an appropriate distance can be reliably secured between the antenna element and a human body, thereby maintaining a good characteristic of the antenna.
