Investigation of SAR on human head modelling using patch antenna in mobile communication for dual band frequency
This paper provides a novel approach to investigate the interaction of human head with mobile handset operating at dual band frequencies such as 900 and 1800 MHz. The applied antenna is rectangular Patch antenna which can be mounted on mobile handset. The human head model is designed as homogenous sphere and stimulated with tissue equivalent material. The Specific Absorption Rate (SAR) of patch antenna has been calculated and variation in far field is observed. It is found that at higher frequency absorption is less. Further specific parameters related to SAR such as overall values, 1 gram and 10 gram are computed. The distance between the antenna and head are varied and results are compared. For SAR calculation, both antenna and head models were designed in FEKO.
