1. Measurement Con ions The measurements were performed in the flat section of the SAM twin phantom filed with head simulating solution of the following electrical parameters at 900 MHz: Relative Dielectrcity 424 5% Conductivity 0.89 mho/m £5% The DASY4 System with a dosimetric E—field probe ET3DV6 (SN:1507, Conversion factor 6.3 at 835 MHz) was used for the measurements. The dipole was mounted on the small tripod so that the dipolfeedpoint was positioned belowthe center marking of the flat phantom section and the dipole was oriented parallelto the body axis (the long side ofthe phantom). The standard measuring distance was 15mmfromdipole center to the solution surface. The included distance 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 250 mW + 3 %. The results are normalized to 1W input power. 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 ET3DV6 SN:1507 and applying the advanced extrapolation are: averaged over 1 em‘ (1 g) of tissue: 9.96 mWig + 168 % (2)‘ averaged over 10 em" (10 g) oftissue: 648 mW/g£162%(k2)‘ ! vlidtion uncerainty

a 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 fromthe SMA—connector to the dipole feedpoint are: Electrical delay 1.391 ns (one direction) Transmission factor: 0.991 (voltage transmission, one direction) "The dipole was positioned at the fat phantom sections according to section 1 and the distance spacer was in place during impedance measurements Feedpoint impedance at 900 MHz RefZ)= 5140 Im {7} = 428 Return Loss at 900 MHz 345 dB 4 Handing Do not apply excessive foree to the dipole arms, because they might bend. Bending ofthe dipole arms stresses the soldered connections near the feedpoint leading to a damage ofthe dipole. & Design The dipole is made of standard semirigid coaxial eable. The center conductor of the feeding line is directly conneeted to the second arm of the dipole. The antenna is therefore short—cireuited for DC— signals 6. Power Test After long term use with 100W radiated power, only a slight warming of the dipole near the feedpoint can be measured.
