Patent ID: 7268564

Claim:
An apparatus for measuring a specific absorption rate (SAR) of a radio communication apparatus, comprising: a first measurement device for measuring in free space a first near magnetic field distribution of a radio wave radiated from an array antenna of a reference antenna including a plurality of minute antennas; a second measurement device for measuring a specific absorption rate (SAR) distribution with respect to the radio wave radiated from said array antenna, with a predetermined phantom using a predetermined measuring method; a first calculation device for calculating a distribution of a transformation coefficient α by dividing said measured specific absorption rate (SAR) distribution by a square of said measured first near magnetic field distribution; a third measurement device for measuring in free space a second near magnetic field distribution of a radio wave radiated from a radio communication apparatus to be measured; and a second calculation device for estimating and calculating a specific absorption rate (SAR) distribution with respect to the radio wave radiated from said radio communication apparatus to be measured, by multiplying a square of said measured second near magnetic field distribution by said calculated distribution of the transformation coefficient α.
