Definitions

  • the present invention relates to a portable(portable phone), and more particularly, to a portable having an antenna structure for reducing the demage of electromagnetic wave, thereby preventing the effect fetal to the brain of an user while radiating harmful electromagnetic wave.
  • a portable is called as a terminal for performing personal portable communication, that is, the personal portable communication using the system such as cellular, CDMA, and PCS and conventionally, according to its miniaturization, an antenna of taking an important view of the portability is used to thus be capable of drawing from the terminal and retracting into the terminal.
  • a whip antenna of top loading type is mainly used to ensure the reception during retraction.
  • the antenna as stated above occurs the problem of directly absorbing the harmful electromagnetic wave r adiated from the antenna at the brain and the hair of the body because the antenna is adjacent to the ear of the body in the communication.
  • the electromagnetic wave is generated from the terminal of the portable phone and radiated through the antenna to the exterior.
  • the electromagnetic wave has effect fetal to the people, especially, to the brain of the body. It has been well-know ⁇ n that, in reality, the electromagnetic wave as stated hereinbefore is mainly radiated from an upper end of the antenna, or, at top loading portion and, while the above antenna is adjacent to the brain of the user in the communication and exposed to the electromagnetic wave, the demage to the human body is serious. In particular, in the case of the woman, while the antenna is contacted to the hairs of the user, the electromagnetic wave is directly transmitted through the hairs to the brain, thereby generating more serious demage.
  • FIG. 1 is a front view showing a portable phone according to an embodiment of the present invention
  • FIG. 2 is a side view showing a portable phone according to an embodiment of the present invention.
  • a portable having a retractable antenna for reducing the demage of electromagnetic wave, including: an antenna for being retractable from a bottom surface of the portable.
  • FIG. 1 is a front view showing a portable phone according to an embodiment of the present invention.
  • the antenna is sticked to the bottom surface of the portable, and draws out to its low position or is retracted into the interior of the portable.
  • FIG. 2 is a side view showing a portable phone according to an embodiment of the present invention, in the case that a charging battery is separated from the portable.
  • the antenna is assembled at the portable by a connection jack 12.
  • the charging battery 2 sticked to the rear surface of the portable 1 is able to be drawn out or retracted into the upper end of the portable 1 and the connection jack 12 is installed at one side of the bottom surface of the portable 1.
  • the antenna 10 engaged to the connection jack 12 is drawn out to its lower position, and upon retracting into the portable, is placed to an edge of the charging battery 2.
  • the antenna is positioned to be farthest from the brain in the state of drawing out the antenna 10, so that the antenna can not be contacted to the hairs.
  • the present invention can remarkably reduce the effect fetal to the brain of the people due to the harmful electromagnetic wave by placing the antenna far from the brain as well as by not contacting the antenna to the hairs in the communication according as the antenna of radiating the electromagnetic wave is placed to its lower position of the portable. Further, while positioning the antenna to the lower position of the portable, the present invention has the effect to easily be retract the antenna by the other hand which does not grip the portable in spite of the communication.
