Abstract

In this paper, a coupled-fed monopole antenna for LTE/WWAN mobile handset applications is presented. The antenna consists of a monopole, a coupling strip, a feeding pad, a stub, and a shorting strip. The basic resonance of the monopole combines with the resonance formed by the coupling that occurs between the coupling strip and the feeding pad to include LTE700(698~787 MHz), GSM850(824~894 MHz), and GSM900(890~960 MHz) bands. The resonance of the stub combines with the harmonics of the monopole to include GSM1800(1,710~1,880 MHz), GSM1900(1,850~1,990 MHz), and UMTS(1,920~2,170 MHz) bands. Therefore, the proposed antenna is suitable as antenna for hexa-band mobile handset applications, covering LTE700, GSM850, GSM900, GSM1800, GSM1900, and UMTS bands. A stable and omni-directional radiation pattern with reasonable gains is observed within the operating bandwidth.

본 논문에서는 LTE/WWAN 이동 통신 단말기 응용을 위해 커플드 급전된 모노폴 안테나를 제안하였다. 이 안테나는 모노폴, 커플링 스트립, 급전 패드, 스터브, 단락 스트립으로 구성되어 있다. 모노폴의 기본 공진과 급전 패드와 커플링 스트립 사이에서 발생하는 커플링에 의한 공진이 결합하여 LTE700(698~787 MHz), GSM-850(824~894 MHz), GSM900(890~960 MHz) 대역을 포함한다. 스터브의 공진은 모노폴의 고조파 성분과 결합하여 GSM1800(1,710~1,880 MHz), GSM1900(1,850~1,990 MHz), UMTS(1,920~2,170 MHz) 대역을 포함한다. 그러므로 제안된 안테나는 LTE700, GSM850, GSM900, GSM1800, GSM1900, UMTS 대역을 포함하는 육중 대역 이동 통신 단말기를 위한 안테나로써 적용이 가능하다. 동작 대역 내에서 방사 패턴은 안정적이고 전방향성이며, 안테나 이득은 적당하다.
