Abstract

This paper presents a method to measure reflection coefficients of microwave devices or antennas based on time domain analysis with sampling oscilloscopes. The reflection coefficients were extracted by the Fourier transformation of echo pulses from devices with respect to the 20 GHz incident pulse signals. The three-error terms, which are commonly used for the correction of a microwave network, were determined using a 3.5 mm calibration kit. In addition, a modified error-correction model associated with a directional coupler for reflection coefficient measurements is introduced. The results were compared with those of measured with a commercial vector network analyzer.

본 논문에서는 샘플링 오실로스코프를 이용한 시간 영역의 해석을 통해 초고주파 소자 및 안테나의 반사 계수를 평가하는 방법을 소개한다. 20 GHz 급의 펄스 입력 신호에 대한 반사 신호를 측정한 후, 이를 푸리에 변환하여 반사 계수를 추출하였다. 초고주파 반사파 회로망의 보정에 필요한 3가지 오차 계수들은 3.5 mm calibration kit을 이용하여 유도하였다. 또한, 반사파 측정을 위하여 결합기를 사용한 경우의 오차 계수를 유도하고, 이를 적용하여 얻은 반사 계수와 벡터 회로망 분석기로 측정한 결과를 비교하였다.
