Patent ID: 6919845

Claim:
A specific absorption rate measuring apparatus for use in a radio apparatus, comprising: a first measurement device for measuring in free space a first near magnetic field of a radio wave radiated from one of a reference radio apparatus and a reference antenna; a second measurement device for measuring a specific absorption rate (SAR) of the radio wave radiated from one of said reference radio apparatus and said reference antenna by using a predetermined phantom according to a predetermined measurement method; a first calculation device for calculating a transformation factor α by dividing the measured specific absorption rate (SAR) by a square value of the measured first near magnetic field; a third measurement device for measuring in free space a second near magnetic field of a radio wave radiated from a radio apparatus to be measured; and a second calculation device for estimating and calculating a specific absorption rate (SAR) of the radio wave radiated from SAR radio apparatus to be measured by multiplying a square value of the measured second near magnetic field by the calculated transformation factor α.
