“…However, many research works were conducted on the interaction between human body and EM energy radiated from wireless communication devices [10]. In one of the first investigation in this area, a study has been performed for the modeling of low SAR antenna considering user interactions [11]. The result reports that a handset with back mounted antenna, which increases the distance between antenna and the head, can produce relatively low SAR to the human head.…”

“…The rms reference antenna power is 0.5 W and the distance between the head and the antenna is 0 mm. The 10-g SAR [23] results are illustrated in Table 3, it is clearly seen that the 10-g SAR results at all frequencies meet the SAR limits of 2.0 W/kg standard. The SAR in the head has a peak of 1.89 W/kg at 2.4 GHz.…”

Compact low specific absorption rate (SAR) hexa‐band planar inverted‐F antenna (PIFA) with independent resonant frequency control is presented in this study. Two trapezoidal shaped slots are etched on the coplanar waveguide (CPW)‐fed PIFA‐radiating plate to create two independent resonant frequencies as well as the fundamental CPW‐fed PIFA itself. Three coupled slots are added within the ground plane to create additional three independent resonant frequencies with slight effect on the other resonant frequencies. Multiband (dual, tri, quad, penta and hexa) band capabilities with bandwidth enhancement and acceptable SAR values are realised for different wireless communication applications. The SAR of human head is investigated by using Computer Simulation Technology (CST) 2012 Microwave Studio Hugo Voxel Model. The proposed antennas are fabricated and there is a good agreement between measured and simulated results.

Low specific absorption rate (SAR) compact hexaband planar inverted‐F antenna (PIFA) with independent resonant frequency control has been studied in this letter. Two trapezoidal‐shaped slots are etched on the coplanar waveguide‐fed PIFA‐radiating plate to create two independent resonant frequencies as well as the fundamental PIFA itself. Three coupled slots are added within the ground plane to create an additional three independent resonant frequencies with slight effect on the other resonant frequencies. Multiband capabilities with bandwidth enhancement and acceptable SAR values are realized for different wireless communication applications. The SAR in the presence of human head is investigated by using CST 2012 Microwave Studio Hugo Voxil Model. The proposed antennas are fabricated, and there is a good agreement between measured and simulated results. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:1802–1810, 2013
