Abstract

Based on the modeling of DGPS antenna and antenna site environment, the DGPS short-monopole antenna performance according to the antenna surrounding environment are analyzed in this paper. The DGPS antenna site modeling that considers the ground conductivity and radio wave obstacles is performed and the general requirements for DGPS antenna site are proposed. In case of antenna site with proper radials on the ground plane of the fixed scale, the effect for antenna matching network due to the ground conductivity and radio wave obstacles is small but the impact on the radiation efficiency is large. To provide the stable DGPS service, it is important to install the DGPS antenna on the flat ground plain with good conductivity and without radio wave obstacles.

본 논문에서는 DGPS 단축형 모노폴 안테나와 안테나 사이트 환경을 모델링하여 안테나 주변 환경에 따른 안테나 성능을 분석한다. DGPS 기준국 안테나의 성능 해석을 위한 모델링을 해석하고 대지 도전율이나 전파 장애물에 의한 안테나 성능을 모의 분석하여 DGPS 안테나 설치에 요구되는 사이트 환경을 정립한다. 일정한 접지 면에 적정한 방사형 접지를 갖는 안테나 사이트는 대지 도전율이나 전파 장애물로 인한 안테나 정합회로에 대한 영향은 적으나, 방사 효율 영향은 크게 나타난다. 안정된 DGPS 서비스를 위해서는 안테나 사이트의 양호한 대지 도전율이외에 주변에 전파 장애물이 없는 평탄한 안테나 사이트가 중요하다.
