Considerations on SAR measurement for recent trend of the usages and new technologies

This manuscript considers Specific Absorption Rate (SAR) measurements for recent usage trends and new technologies. The SAR of a Universal Serial Bus (USB) dongle wireless device inserted into host device, e.g., a laptop PC, is investigated based on numerical simulation and measurement. Then the SAR from antennas built into a laptop PC is studied based on numerical simulations. Another important issue is how to measure the SAR with respect to new technologies such Long Term Evolution (LTE) devices.
