<p>The present invention provides reduction of injury to human body by effectively reducing short-distance electromagnetic wave without any influence on long-distance electromagnetic wave which acts upon the telephone communication amongst electromagnetic waves radiated from antenna of mobile communication terminal. An electromagnetic wave absorber absorbing short-distance electromagnetic wave, is installed at outcrier of metal road fixed to a helical antenna, and upper portion of electromagnetic wave absorber, is formed in a manner that it has a big diameter, and lower portion having a small diameter is formed and a through bore is formed at the central portion, therefore said metal road is inserted at through bore or is in its entirety formed as a cylinder and formation of through bore at the central portion leads said helical antenna to be inserted at through bore or leads electromagnetic wave absorber to be inserted and integrally formed.</p> |
