Comparison between CTIA hand phantom and different human hands for OTA power measurements

This study investigates the Over the Air (OTA) power measurements from a mobile phone when held by the CTIA hand phantom compared to a number of participant´s hands. A measurement setup in a shielded environment was setup to ensure that all the participants held the mobile phone in a similar fashion to the hand phantom so that accurate comparisons could be made. Measured results show that the received power from all the participants was lower than that received from the hand phantom when the index finger covered the whole antenna region.
