Body Loss Measurements of Internal Terminal Antennas in Talk Position using Real Human Operator

Measured results of three typical internal mobile phone antennas held in talk-position by a real human operator are presented. Depending on exact placement of index finger, frequency band and type/position of radiator, total body losses ranging from 6-26 dB have been measured. In all cases, the absorption loss was much more significant than the mismatch loss. The monopole (off-ground) antenna was more affected by the head+hand than the PIFA antennas, in particular for the common placement in the bottom of the phone.
