초록

본 논문에서는 1-15GHz 주파수 대역에서 동작하는 초광대역 인쇄형 반원모양 다이폴 안테나에 대한 설계 방법을 연구하였다. 반원모양 다이폴의 두 팔 사이의 간격과 반원의 반지름 변화에 따른 입력 반사계수와 이득 특성을 분석하여 최적의 설계 변수를 도출하였다. 최적화된 인쇄형 반원모양 다이폴 안테나를 FR4 기판 상에 제작하고 특성을 실험한 결과 전압 정재파비(VSWR; voltage standing wave) < 2인 대역이 1-15 GHz (175%)으로 초광대역 특성을 갖는 것을 확인하였다.

In this paper, a design method for a ultra-wideband printed semi-circular-shaped dipole antenna operating in the band of 1-15 GHz is studied. The effects of the gap between the two arms of the semi-circular-shaped dipole and the radius of the semi-circle on the input reflection coefficient and gain characteristics are examined to obtain the optimal design parameters. The optimized printed semi-circular-shaped dipole antenna is fabricated on an FR4 substrate and the experimental results show that the antenna has a desired extremely wideband characteristic with a frequency band of 1-15 GHz (175%) for a VSWR < 2.
