RAYSPANŽ Proprietary Metamaterial Antennas
A Proven SAR Reduction Solution
Abstract
Rapid advances in the personal communications industry and the ubiquitous use of cellular phones throughout much of the world have increased concern about the effects of radio frequency radiation from these devices on public health. Regulatory bodies in the United States and Europe have defined the allowable Specific Absorption Rate or SAR in order to ensure that radiation emitted by personal communications devices is safe for the public. Mobile phone manufacturers have used various methods to control or lower the SAR in order to meet these regulations. In a recent article in the British Telegraph, the BL-40 handset from LG, the first ever to utilize a metamaterial antenna based on a proprietary RAYSPANŽ solution, was declared the phone with the lowest SAR value when compared with some of the most popular handsets currently sold in Europe. RAYSPANŽ engineering team has also observed SAR improvement of up to 50%, when conventional antennas in production handsets are replaced with RAYSPANŽ metamaterial antennas.
