1. Measurement Conditions The measurements were performed in the flat section of the SAM twin phantom filled with head simulating solution of the following electrical parameters at 2450 MHz: Relative Dielectricity 37.6 £5% Conductivity 1.88 mho/m +5% The DASY4 System with a dosimetric E—field probe ES3DV2 (SN:3013, Conversion factor 4.8 at 2450 MHz) was used for the measurements. The dipole was mounted on the small tripod so that the dipole feedpoint was positioned below the center marking of the flat phantom section and the dipole was oriented parallel to the body axis(the long side of the phantom). The standard measuring distance was 10mm from dipole center to the solution surface. Lossless spacer was used during measurements for accurate distance positioning. The coarse grid with a grid spacing of 1 5mm was aligned with the dipole. The 7x7x7 fine cube was chosen for cube integration. The dipole input power (forward power) was 250mW +3 %. The results are normalized to 1 W input power. 2. SAR Measurement with DASY4 System Standard SAR—measurements were performed according to the measurement conditions described in section 1. The results (see figure supplied) have been normalized to a dipole input power of 1 W (forward power). The resulting averaged SAR—values measured with the dosimetric probe ES3DV2 SN:3013 and applying the advanced extrapolation are: averaged over 1 cm‘ (1 g) of tissue: 58.4 mWig + 16.8 % (=2)‘ averaged over 10 cm‘ (10 g) oftissue: 26.4 mWig +16.2 % (—2)‘ ‘ validation uncertainty

3. Dipole Impedance and Return Loss The impedance was measured at the SMA—connector with a network analyzer and numerically transformed to the dipole feedpoint. The transformation parameters from the SMA—connectorto the dipole feedpoint are: Electrical delay: 1.154 ns (one direction) Transmission factor: 0.993 (voltage transmission, one direction) The dipole was positioned at the flat phantom sections according to section 1 and the distance spacer was in place during impedance measurements. Feedpoint impedance at 2450 MHz: Re{Z} = 53.0 o Im {Z} =3.5 0 Return Loss at 2450 MHz —27.0 dB 4. Measurement Conditions The measurements were performed in the flat section of the SAM twin phantom filled with body simulating solution of the following electrical parameters at 2450 MHz: Relative Dielectricity 52.0 +5% Conductivity 2.00 mho/m +5% The DASY4 System with a dosimetric E—field probe ES3DV2 (SN:3013, Conversion factor 4.02 at 2450 MHz) was used for the measurements. The dipole was mounted on the small triped so that the dipole feedpoint was positioned below the center marking ofthe flat phantom section and the dipole was oriented parallel to the body axis(the long side of the phantom). The standard measuring distance was 10mm from dipole center to the solution surface. Lossless spacer was used during measurements for accurate distance positioning. The coarse grid with a grid spacing of 15mm was aligned with the dipole. The 7x7x7 fine cube was chosen for cube integration. The dipole input power (forward power) was 250mW + 3 %. The results are normalized to 1 W input power.

5. SAR Measurement with DASY4 System Standard SAR—measurements were performed according to the measurement conditions described in section 4. The results (see figure supplied) have been normalized to a dipole input power of 1 W (forward power). The resulting averaged SAR—values measured with the dosimetric probe ES3DV2 SN:3013 and applying the advanced extrapolation are: averaged over 1 cm> (1 g) of tissue: 53.6 mWig + 16.8 % (=2) averaged over 10 cm> (10 g) of tissue: 25 mWig + 16.2 % (k=2) 6. Dipole Impedance and Return Loss The dipole was positioned at the flat phantom sections according to section 4 and the distance spacer was in place during impedance measurements. Feedpoint impedance at 2450 MHz: Re{Z} = 48.60 Im {Z} = 5.8 0 Return Loss at 2450 MHz —24.4 dB 7. Handling Do not apply excessive force to the dipole arms, because they might bend. Bending ofthe dipole arms stresses the soldered connections near the feedpoint leading to a damage of the dipole. 8. Design The dipole is made of standard semirigid coaxial cable. The center conductor ofthe feeding line is directly connected to the second arm of the dipole. The antennais therefore short—circuited for DC— signals. Small end caps have been added to the dipole arms in order to improve matching when loaded according to the position as explained in Sections land 4. The SAR data are not affected by this change. The overall dipole length is still according to the Standard. 9. Power Test After long term use with 40W radiated power, only a slight warming of the dipole near the feedpoint can be measured. * validation uncertainty
