SAR Reduction Using Integration of PIFA and AMC Structure for Pentaband Mobile Terminals
Published 2017-01-01“…Even though the AMC structure is operated at a high band, the effect against the head could be reduced in the pentaband due to the spreading effect of the electromagnetic (EM) field at lower bands. From measured results, the 1 g SAR in the case of the AMC antenna is significantly lower than that in the case where only the PIFA is present in the pentaband.…”
