Abstract

In this paper, PIFA on PCS handset for SAR reduction is designed. According to the position of PIFA attached on the handset, side mounted PIFA and top mounted PIFA are suggested. Resonance characteristics with variety of design parameters are analyzed. And monopole antenna with $\lambda$/4 length is designed and compared with PIFAs in bandwidth and SAR. At 1.83 GHz center frequency, the bandwidth of side mounted PIFA and monopole antenna are 8.2% and 21.7%, respectively. The 1 g and 10 g peak average SARs of side mounted PIFA are 0.686 and 0.353 respectively, which are about 1/3 of SARs of monopole antenna, 1.759 and 0.978, respectively.

본 논문에서는 SAR을 저감시킬 수 있는 pes용 PIFA를 설계하였다. 안테나가 부착되는 위치에 따라 top m mounted PIFA와 side mounted PIF A의 두 가지 PIFA를 제안하고. 안테나의 설계 파라미터에 따른 공진 특성 을 분석하였다 제안한 PIFA와 통일한 공진 주파수를 갖는 모노폴을 설계하여 대역폭과 SAR 값을 비교. 분석 하였다. 중심 주파수 1.83 GHz에서 Side mounted PIF A와 모노폴 안테나의 대역폭은 각각 8.2 %와 21.7 %로 나 타났다. Side mounted PIF A의 SAR 값은 19 및 109 평균 첨두치가 0.686. 0.353으로 모노폴 안테나에 대한 S SAR 값인 1.759. 0.978에 비해 약 1/3로 나타났다
