Design of Ultra-Wide Band Slotted PIFA for Wireless Devices
Abstract: The design of an ultra-wideband planar inverted-F antenna (PIFA) is proposed for mobile phone applications in this paper. The different slots are introduced on radiating patch and ground plane. The volume of the radiating antenna is 40x40x3.5 mm3 which is small as compared to reported work. The ultra-wide bandwidth with acceptable return loss –6 dB is obtained from 4.6 to 30 GHz with good matching and radiation characteristics. Different performance …

Evaluation of SAR and Temperature Elevation in Human Head for Advanced Wireless Services (AWS) Application
Abstract: In this paper, the specific absorption rate (SAR) and the temperature rise in the SAM phantom human head model as a consequence of the exposure to radiation of planar inverted F (PIFA) mobile handset antenna has been estimated at Advanced Wireless Services (AWS) band downlink frequency range. Biological hazards on human head owing to electromagnetic wave (EMW) exposure in advanced wireless services has been analyzed by computing the temperature rise …
