Abstract

In this paper, the characteristics of a series-fed dipole pair antenna with an end-aligned strip pair director are studied. In the proposed SDP antenna, two strip dipole antennas with different lengths and a ground reflector are connected trough a coplanar stripline. The strip pair director placed above the second dipole element are two rectangular-shaped strips and is aligned at the ends of the two arms of the second dipole. The variations on the antenna performance for different lengths and widths of the director are analyzed, and optimal design parameters for the enhancement of the bandwidth are obtained. The optimized SDP antenna is fabricated on an FR4 substrate, and the experimental results show that the antenna has a frequency band of 1.65-2.95 GHz for a VSWR < 2, which shows enhanced bandwidth compared to the conventional SDP antenna.

본 논문에서는 종단 정렬된 스트립 쌍 도파기를 가지는 직렬 급전 다이폴 쌍 (series-fed dipole pair; SDP) 안테나의 특성에 관하여 연구하였다. 제안된 SDP 안테나는 두 개의 서로 다른 길이의 스트립 다이폴 안테나와 접지 반사기가 코플래너 스트립 (coplanar strip; CPS) 선로로 연결되어 있다. 두 번째 다이폴 위쪽에 추가된 스트립 쌍 도파기는 두 개의 직사각형 모양의 스트립이며 두 번째 다이폴의 양팔의 종단에 정렬되어 있다. 종단 정렬된 스트립 쌍 도파기의 길이와 폭에 따른 안테나의 특성 변화를 분석하여 대역폭 향상을 위한 최적의 설계 변수를 얻었다. 최적화된 SDP 안테나를 FR4 기판 상에 제작하고 특성을 실험한 결과 전압 정재파비(voltage standing wave ratio; VSWR)가 2 이하인 대역은 1.65-2.93GHz이고, 대역폭이 기존 SDP 안테나에 비해 증가함을 확인하였다.
