초록

본 논문에서는 지난 호 브랜치 루프안테나 BLA(Branch Loop Antenna)에 이어 휴대 단말기용 연장 루프안테나를 설계한다. 사각형 루프에 연장 루프를 추가한 ELA(Extended Loop Antenna)를 소개하고, 휴대 단말기에 적용될 수 있음을 보인다. 연장 루프 소자를 사각형 루프안테나 상단 및 좌우양단에 추가하고, 길이를 조절하여 낮은 공진 주파수를 얻는다. 연장 루프에 의한 다중 공진을 얻고, 접속위치와 길이로부터 원하는 대역을 얻는다. 설계한 ELA를 구현한 후 측정으로부터, CDMA/GSM의 낮은 주파수 대역에서 평균이득 -3.0~-1.46dBi 및 50.15~71.41% 효율의 양호한 특성을 얻었고, DCS/USPCS/WCDMA의 높은 주파수 대역에서는 평균이득 -8.28~-1.7dBi 및 14.87~67.68% 효율을 얻었다.

An extended loop antenna, to be continued BLA(Branch Loop Antenna) in the previous volume, for the mobile handset is designed in this paper. It's introduced an ELA(Extended Loop Antenna) that is added extended loops to rectangular loop, and verified antenna performances for applying to mobile handset. Extended loops are located upside, left and right side of rectangular loop, and low resonance is obtained by the length of line. Multiple resonances are established by the extended loops, and obtained the desired service bands by the connection points and lengths. By the implementation and measurement for the multiband ELA, it's showed -3.0~-1.46dBi average gains with 50.15~71.41% efficiencies at CDMA/GSM frequency band, and -8.28~-1.7dBi average gains with 14.87~67.68% efficiencies at DCS/USPCS/WCDMA frequency band.
