Abstract
In this paper, we propose a low-cost near-field measurement system using a circular cylindrical scanning formula in order to obtain the radiation pattern of an AUT (Antenna Under Test). Near-field measurement is performed with the improved circular cylindrical scanning based on a planar scanning. We propose a novel method that replaces a network analyzer and we also offer the specifications of the near-field measurement system.
안테나의 특성 중 지향성(Directivity)과 관계있는 방사 패턴을 측정하기 위한 저가의 근역장 측정 시스템을 설계한다. 근역장 측정방법은 평면주사법에 기반을 둔 개선된 원통형 주사법 공식을 이용한다. 고가의 측정 장비인 네트워크 분석기를 대체하기 위한 방법을 제시하고 필요한 장치 규격을 제안한다.
