Low SAR ferrite handset antenna design

Further research on the low SAR ferrite coated monopole handset antenna concept shows that different metallization geometries are non-unique regarding their influence on antenna multi-band performance. Simulation models with new metallization geometries are described and the techniques are extended to a balanced antenna previously developed by Antenova Ltd. Recent results of the ferrite adapted version illustrate the control of the multi-band structure while maintaining an overall low SAR performance and reasonable radiation efficiencies. Further research is identified and conclusions reached.
