Abstract: In this paper, a metamaterial embedded
planar inverted-F antenna (PIFA) is proposed for cellular phone. A dual band
PIFA is designed to operate both GSM 900 MHz and DCS 1800 MHz. The ground
plane of conventional PIFA is modified using a double negative (DNG)
metamaterial array. The investigation is performed using the Finite
Integration Technique (FIT) of CST Microwave Studio. The specific absorption
rate (SAR) values are calculated considering two different holding
positions-cheek and tilt. The results indicate that the proposed
metamaterial embedded antenna produces lower SAR in the human head compared
to conventional PIFA. Moreover, the modified antenna substrate leads to
slight improvement of the antenna performances.
