APPARATUS FOR BODY PROTECTION FROM ELECTROMAGNETIC FIELDS

摘要

PURPOSE: An apparatus for protecting a human body from an electromagnetic wave is provided to suppress an absorption rate of an electromagnetic wave by controlling a radiation pattern from an electronic device through a radiator which comprises an antenna. CONSTITUTION: An antenna board is arranged in the upper center of a periodic structure. An antenna is formed on an antenna board. A via(145) grounds the antenna board and the antenna. A feeding terminal(147) feeds a signal by electrically connecting the antenna board and the antenna. A plurality of unit cells are periodically arranged on the periodic structure.
