Abstract

The analysis and comparison of two types of EBG structures: mushroom-like EBG and UC-EBG to reduce the electromagnetic waves radiated from mobile phone has been presented in this paper. The stop band for each EBG structure has been designed at operation bands of mobile phone radiation. The results revealed that mushroom-like EBG structure gives a higher reduction of SAR compared than the UC-EBG. Besides, the results also indicated that the number of EBG elements play an important role in the SAR reduction effectiveness. The human head can be protected from unwanted electromagnetic radiations by placing the EBG structure in between antenna and human head.
