CONSTRUCTION AND CHARACTERIZATION OF DIPOLE ANTENNA TO BE USEDIN SAR MEASUREMENTS

Verification of specific absorption rate measurement system isnecessary before determining the specific absorption rate value ofmobile phones. the specific absorption rate measurement system,including the electric field probe, the tissue equivalent liquid and robotused for positioning the probe and also the special software, should bevalidated in order to check whether it works correctly or not at the testfrequency. a flat phantom and a reference dipole antenna are used forthe system verification. the reference dipole antenna is placed at thebottom of the flat phantom. so, electric field is formed inside the liquidby applying a known power is delivered to dipole antenna to the tissueequivalent liquid. in this study, the construction, characterization andvalidation measurements of reference dipole antenna which is one ofthe important components of validation measurements will bediscussed.
