Abstract

This paper is studied for the design and experiment of a wideband printed 1x2 dipole array antenna for 3.5GHz band application. The printed dipole antenna used in the array antenna was implemented in the form of a rectangular strip, and was consisted with a broadside coupled stripline (BCS). The feed line was designed to be tapered for broadband impedance matching. As a result of comparing the simulation results and measurement results, it was found that the two results were in good agreement with 2.8% error(100MHz shift @3.5GHz). As a result of the experiment, based on VSWR=2, a bandwidth of about 16% was obtained from the center frequency of 3.5 GHz to 3.15~3.70 GHz.

본 논문은 3.5GHz 대역 응용을 위한 광대역 프린트 1x2 다이폴 배열 안테나의 설계 및 실험에 관해 연구 한 것이다. 프린트 배열 다이폴 안테나의 각각 형태는 직사각형 스트립 모양으로 구현되었으며, 광대역 특성을 갖도록 양면의 다이폴 안테나 구조는 측면 결합 선로(BCS: broadside coupled stripline)로 구성된다. 급전선은 광대역 임피던스 정합을 위해 테이퍼형으로 설계되었다. 시뮬레이션 결과와 측정 결과를 비교한 결과, 두 결과가 2.8%(100MHz 이동 @3.5GHz) 차이를 보여 서로 잘 일치하는 것으로 나타났다. 실험 결과 VSWR=2인 점을 기준으로 대역폭은 중심 주파수 3.5 GHz에서 3.15~3.70 GHz까지 약 16%의 대역폭을 얻었다.
