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...
Basic principle of ultrasound medical imaging is a direct adaptation of that of phased array radar. Modern ultrasound scanners use large either linear or phased array of piezoelectric (PZT, for instance) transducers. Designing electronic beam-forming network for ultrasound pulsed echo system is thus very much similar to the adaptive antenna array system design in a different modality. When ultr...
