Example of SAR reduction in a mobile phone
The data shown here are examples of in-house meas-
urement and may not coincide with performance in
other situations.
Currently, legislation to regulate the SAR(Specif-
ic Absorption Rate) of mobile phone radiation
potentially damaging to the human head (Less
than 2W/Kg in Japan) is underway globally. By
using Flexield at appropriate positions for large
magnetic shield and electromagnetic loss
effects, highly efficient SAR countermeasures,
which don't damage the far electrical field
strength that determines transmission and re-
ception performance, can be expected.
The following example shows the benefits of
SAR reduction using a simulated mobile phone
with the carrier wave set at 900MHz. In this case,
Flexield was applied to the back of the liquid
crystal panel. SAR reduction of more than 30%
was achieved.
The decline of the far electric field level was less
than a few percent, and it was confirmed that
practical transmission performance could be
maintained.
If the application of sheet Flexield for SAR reduc-
tion using punched Flexield shapes is consid-
ered when designing a mobile phone, optimum
materials, shapes, sizes (thickness and area),
and locations, can be determined in a most
effective manner.
