Abstract
In this paper, we measured how human bodies affect to antennas for Portable Computer Terminals by using half wave dipole antenna, and how the display angle of Portable Computer Terminals affects to the characteristics of the antennas. Then the dipole antenna is attached to a note type PC, and we measured and discussed how the attached place and affects direction effects radiation directivity of the antenna. Furthermore a ceramic phantom in front of the note type PC on which the dipole antenna is attached, and we measure the directivity of the antenna. We showed and discussed that how the ceramic phantom effects to the antenna.
