Cell phone antenna radiation effect on organisms

Rate this Entry
To simulate a cell phone antenna to study the effect of the radiation on organisms, a simulation to evaluate cell phone antenna in the presence of a human body, with particular emphasis on the head and hand is carried out. In accordance with IEEE standards, such as 1528, the Standard Anthropomorphic Model is used as the head model. The frequency dependent dielectric properties of the tissue simulating liquid are also defined by this standard and can be modeled as a dispersive material in the simulation tool.

You also need to do SAR calculation. SAR is a measure of the rate of RF energy absorption by the body from the source being measured.To test cell phones for SAR compliance, the phone is precisely placed in various common positions next to the head and body, and a robotic probe takes a series of measurements of the electric field at specific pinpoint locations in a very precise, grid-like pattern within the dummy head and torso. Only the highest SAR values for each frequency band are included in the final authorization to demonstrate compliance with the FCC’s RF guidelines.
