Specific absorption rate distribution and radiation pattern in human head subjected to mobile phone radiation at different frequencies

الملخص EN

Many wireless communication devices are used with their antennas in close proximity of the human head.

This fact changes the antenna characteristics and affects the communications performance on one hand, and causes the deposition of microwave energy in the user's head, on the other hand.

The amount of power absorbed by the human body is limited to a given maximum value, according to the two standards IEEECg$.i and EN 50360.

In this paper the design of a multiband compact antenna for integration into the multifunction mobile phones is presented.

Return loss coefficient and radiation pattern of this antenna are computed in free space as well as in the presence of human head model.

The specific absorption rate (SAR) of the planar antenna is calculated.
