Abstract
Disclosed herein includes a wireless electronic device, including an outer casing, an antenna, and a metallic sheet. The outer casing may be electrically non-conductive. The antenna may be disposed within the outer casing and configured to perform wireless communication of signals at an operating wavelength of λ unit length. The metallic sheet may be disposed on a portion of the outer casing and placed at a distance of at least λ/25 unit length apart from the antenna. The metallic sheet may be configured to shield a subject exposed to energy radiated by the antenna to limit the specific absorption rate (SAR) of the subject to less than 1.6 W/kg.
