Comparison Specific Absorption Rate (SAR) for Human Head between 2G and 4G Mobile Communication

Comparison the specific absorption rate of the human head model between the second generation (2G)and the fourth generation (4G) of mobile phone communication. rectangular micro strip patch antenna was designed and operated at (1.8 & 2.3) GHz for Global system of mobile communication (GSM)and long term evolution (LTE) applications respectively. Placing the antenna close to the human head model and all the simulation executed using the CST program. The obtained results for the comparison in the second generation is smallest from the specific absorption rate level in the fourth generation, and the specific absorption rate level in (2G and 4G) well below the limitation value recommended by FCC and IEEE.
