초록
본 논문에서는 Ku대역 통신시스템을 사용하는 큐브 위성에 장착이 가능한 평면배열안테나 있어, isoflux 방사특성을 유도하기위한 급전신호 가중치 분석에 관하여 연구하였다. 평면배열안테나는 큐브위성 장착성을 고려하여 8*8개의 방사소자를평면 배열하였으며, 각 축 기준 방사소자 간 간격은 0.5 lambda로 설정하였다. isoflux 방사특성 유도를 위한 급전신호 가중치는 저대역 통과필터 설계에 활용되는 신호처리 기법을 이용하여 산출하는 방법을 제시하였다. 본 논문에서 제안된 방법의분석 결과 원활한 isoflux 패턴을 유도할 수 있음을 확인하였다.
Abstract
In this paper, we studied the derivation method of isoflux radiation for a planar array antenna. The presented arrayantenna was designed for considering of 1U-sized CubeSAT with Ku-band communications. For the presented arrayantenna, 8×8 radiating elements were arranged, and the distance between radiating elements was set of half-wavelength. The excited current weighting for each radiating elements was calculated by the signal processing technique used in thedesign of the low-pass filter. As a result of analysis of the method proposed in this paper, it was confirmed that aseamless isoflux pattern can be derived.
