Problems solved by technology

[0008] Similar to the above, a terminal equipped with an existing stylus and antenna basically uses a helical antenna, uses the stylus as a single-stage antenna, and uses the stylus separately from the body when using a portable information terminal In addition, when it is separated from the fuselage, the situation of loss will continue to occur, and it may not be possible to use a single-stage antenna. Therefore, this input pen and antenna cannot provide good information sensitivity.
