“…However, the cube model of the human head has reliability issues and calculation of gap length. Effect on electromagnetic absorption towards the human head with different substrates is studied at three different frequencies by Ramli et al In this work, he varied dielectric values and calculated the heat conductivity and permittivity, but the setup source is helical antenna lacking shielding. Iacono et al investigated SAR in deep brain stimulation in human head and estimated Peak SAR.…”

“…The major setback in this estimation technique is thermoregulatory response changes due to sweat mechanism. Ramli et al reported that the SAR estimation is dependent on the percentage due to change in dielectric permittivity of the tissues. The 1 gram and 10 grams estimation fluctuation are a primary disadvantage due to the effect of the substrate material.…”

Specific Absorption Rate (SAR) is an inevitable parameter to be considered for various RF dosimetry evaluations in the field of biomedical engineering. There is a much concern in exposure studies as they have a significant impact on the social and health issues in the recent global community. SAR measures the absorption of electromagnetic radiation of RF from devices in an exposure area. The significance of SAR parameter has been awakened in broad areas of technology and even considered in the design of radiating structures from biomedical devices such as MRI to also popular mobile phones. Researchers have explicated the constant interaction of electromagnetic field interactions with biological systems. The advancements in technology pose a grave concern about the impact on human health. This paper intends to undertake an extensive survey of the various current investigations done with SAR in different scenarios with possible radiating structures and also focus on exposure areas on the human body. The SAR depends on estimation parameters that are analyzed and discussed. Further, the paper will analyze comparatively the facets of implied Methodologies in SAR computation. The parametric evaluation of SAR paves the way for a requirement reduction of SAR parameter. The paper discusses current reduction methodologies and its primary advantages and details possible setbacks. The analysis indicates a requirement of the specific radiation structure for a particular area of exposure of concern, followed by a need of ideal reduction methodology.

The enhancement technologies of wireless body area network improved the health monitoring system. Previous work have been designed the implantable chip printed antenna at 4.8 GHz. This paper is continuing the investigation where the antenna wave propagation in term of attenuation and polarization were studied. The antenna is implanted in human hand voxel model from CST Microwave Studio Software. The performances of the antenna are evaluated in term of return loss, gain and efficiency. Results show that the rate attenuation for the propagation is approximately 0.16 dB up to 0.42 dB. All the results will be guidelines in designing implantable antennas in futures.

Abstract-In this paper, periodic structures are investigated in antenna design for wireless applications. These antennas were compared with CRLH miniaturization method. Three different models of patch antenna with coaxial feed on EBG ground, metamaterial substrate or EBG/AMC structure have been presented here. Also two compact dual-band antennas have been designed and fabricated based on CRLH techniques for wireless and GSM applications. The first antenna has directional pattern and operates at 1760, 2550 and 3850 MHz (three-band antenna) with gain 2.1, −3.9 and 2.5 dBi, and it is dual polarized. The size of prototype patch antenna is 20 × 20 mm 2 which is reduced about 47% in comparison to conventional patch antenna at 2.5 GHz. The second antenna is designed by the use of interdigital capacitor and spiral inductor. Dimensions of antenna are 15.5×12 mm 2 , so the size is reduced about 69% in comparison to conventional microstrip patch antennas at 1.8 GHz. The second tri-band antenna operates at 1060 MHz, 1800 MHz and 2500 MHz in which two frequencies (1.8 and 2.5 GHz) are suitable for GMS and WLAN applications. Both structures have been designed and fabricated on FR4 low cost substrate with ε r = 4.4 and thickness of 1.6 mm. All simulations are done with CST and HFSS. Equivalent circuit and experimental results are also presented and compared.
