The SAR value analysis of LTE terminals

LTE is the newly emerging telecommunication mode. Owing to its multiple antennas and high frequency radiation characteristics, its electromagnetic radiation and SAR value are different with terminals operating with other modes. Simulation model of LTE terminal with MIMO antenna is constructed in this paper. Radiation and SAR value of different telecommunication modes are compared with simulation and test. During the simulation, the input power for different mode is set the same to obtain meaningful comparison. On the other hand, terminals are operating with their maximum emission power in the SAR test according to the specification. It can be seen that LTE terminals has the highest SAR although it has low emission power. It gives some insight into analysis of telecommunication terminals operated in different modes.
