This paper presents a printed wideband monopole antenna for multi-standard handheld terminals in mobile wireless communications that covers the operating frequency bands of GPS (1.565–1.585 GHz), GSM (1800, 1900, and 2100 MHz), WiMAX (3.2–3.6 GHz), WLAN, Bluetooth (2.4 GHz) and WLAN (5.47–5.9 GHz). The antenna is integrated with a semi-circular-shaped radiating patch, additional rectangular radiating...
The aim of this paper is to investigate the effects of the distance between the human head and internal cellular device antenna on the specific absorption rate (SAR). The effects of the metal-glass casing of mobile phone on the SAR values were observed in the vicinity of the human head model. Additionally, the reflection coefficients were investigated in all cases to evaluate antenna performance....
The purpose of this paper is to calculate the specific absorption rate (SAR) reduction in muscle cube with metamaterial attachment. The finite-difference time-domain (FDTD) method has been used to evaluate the SAR in a realistic anatomically based model of the muscle cube. We design the single negative metamaterials from periodic arrangement of split ring resonators (SRRS). By properly designing structural...
