Title:
移動通信端末の電磁波縮減装置
Document Type and Number:
Japanese Patent JP2004515950
Kind Code:
A
Abstract:
The present invention provides reduction of injury to the human body by effectively reducing short-distance electromagnetic waves without any influence on long-distance electromagnetic waves which act upon a telephone communication amongst electromagnetic waves radiated from antenna of mobile communication terminals. An electromagnetic wave absorber, absorbing short-distance electromagnetic wave, is installed at the exterior of a metal rod fixed to a helical antenna, an upper portion of the electromagnetic wave absorber is formed having a big diameter, a lower portion is formed having a small diameter, and a through bore is formed at the central portion, said metal rod being inserted at through bore or is in its entirety formed as a cylinder, and formation of a 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 thereon.
