[ 1 ] - کاهش اثرات امواج موبایل به کمک آنتنهای آرایهای و تفکیک یک نقطه داغ به چند نقطه داغ

In this paper, new method for reduction of Specific Absorption Rate (SAR) in mobile handset is presented. The idea is based on the array antenna theory and this caused that by improvement of the gain, SNR be preserved and instead of one antenna and one strong hotspot, have the two antenna with two weak hotspot. For this array, the antenna must be equal with similar pattern to have the best arra...
