eduction is designed. Frequency characteristics and SAR value optimized with various design parameters are
analyzed and designed. Designed internal monopole antenna mounted on the handset is simulated. The 1 g
and 10 g peak average SARs of the internal monopole antenna are 0.656 and 0.387 W/kg respectively. And
the internal monopole antenna and external monopole antenna attached on the handset are tested. As a result,
the 1 g and 10 g peak average SARs of the internal monopole antenna are 0.686 and 0.356 W/kg. And results
the external monopole antenna are 1.33 and 0.812 W/kg, respectively. So the internal monopole antenna has a
about 50 % reduced SAR value in comparison with external monopole antenna.
