Commercial Release of IEC 62209-3 Validation Antennas

The acceptance and standardization of fast specific absorption rate (SAR) systems will simplify SAR compliance testing for manufacturers, test labs and regulators. To accelerate the process, SPEAG has commercially released the full set of standardized high-precision antennas (AVALSET-3V1) that are fundamental in order to prove that ‘dry’ test systems meet the requirements of the upcoming IEC 62209-3 standard. Last week in London, all parties agreed on all technical details regarding antennas and procedures. The Publicly Available Specifications (PAS) will be submitted by August 2017.

By using these antennas, manufacturers as well as any independent third-party are now able to verify that the output data is correct and the SAR system - within its boundaries of the specifications and corresponding uncertainty as determined according to the standard - does not provide erroneous measurement results for the device under test (DUT). The antennas have been developed in a two-year-effort by the IT’IS Foundation under the mandate and in collaboration with the Standard Working Group of IEC 62209-3, and meet the requirements to encompass the whole range of field distributions and signal types encountered with currently available mobile communications devices.

The set consists of 11 dipole antennas, four vertical planar inverted-F antennas (VPIFAs) and one dual-peak centrally fed planar inverted F-antenna (CPIFA), all being in accordance with the mechanical tolerances as specified in the standard. To confirm accuracy and reliability of performance, each antenna is measured using the latest DASY6 system to verify the numerically determined target values. The repeatability of the calibration was cross-checked for two sample sets in a recent study including the US Federal Communications Commission (FCC), ISED Canada, China Telecommunication Technology Labs (CTTL), PC Test and the IT’IS Foundation. During the past month, the antennas and highly stable power sources were applied in a series of validations performed on two commercially available systems, one of which being SPEAG’s cSAR3D. The results of this side-by-side study confirm that applying these antennas with the power and modulation settings, test procedure and acceptance criteria as defined in the standard, reliably detect the performance and limitations of these systems; they also identify cases for which the uncertainty budgets are too optimistic (details are available from the IT’IS Foundation ( It should be noted that the results are in line with the recently performed inter-laboratory study under auspices of ISED Canada that used commercial phones to evaluate if dry systems are suitable for screening. Additional studies are currently performed by at least one other lab.

Please do not hesitate to consult SPEAG for additional information or to receive a quote for the validation antenna set. It should be noted that manufacturers only need to perform regular validations of their vector-based array SAR systems.
