유전체 렌즈가 있는 한 쌍의 혼 안테나를 사용하는 자유 공간 방법에서 측정된 샘플의 투과 계수를 가우스 빔의 투과 계수와 동일화함으로써 샘플의 유전율을 매우 정확하게 추정할 수 있음을 입증했습니다. 평면파의 투과 계수에 위상을 변경하는 항을 곱한 것과 거의 같습니다. 이 유전율 추정 방법에서는 가우시안 빔에서 빔 웨이스트의 스폿 크기를 결정해야 하기 때문에 Thru-Reflect-Line 교정에서 라인 측정을 사용하여 스폿 크기를 추정하는 방법을 제안했습니다. 따라서 추가 측정이 필요하지 않습니다. 유전율 추정 방법은 E-band (60-90 GHz), 두께 2mm의 공기와 비유전율 2.05, 두께 1mm의 시료의 비유전율은 ±0.5%, ±0.2 미만의 오차로 추정됨이 입증되었습니다. %입니다. 또한, 측정 오류를 피하기 위해 수신 혼 안테나를 교체하지 않고 샘플을 측정할 때 벡터 네트워크 분석기를 사용하여 측정된 S 매개변수에 대한 유전율 추정 표현식을 도출하고 안테나 변위 없이 샘플을 측정하는 것이 유효함을 입증했습니다. .

Abstract: In a free-space method using a pair of horn antennas with dielectric lenses, we demonstrated that the permittivity of a sample can be estimated with good accuracy by equalizing a measured transmission coefficient of a sample to a transmission coefficient for a Gaussian beam, which is approximately equal to the transmission coefficient for a plane wave multiplied by a term that changes the phase. In this permittivity estimation method, because the spot size at the beam waist in a Gaussian beam needs to be determined, we proposed an estimation method of the spot size by employing the measurement of the Line in Thru-Reflect-Line calibration; thus, no additional measurement is required. The permittivity estimation method was investigated for the E-band (60-90 GHz), and it was demonstrated that the relative permittivity of air with a thickness of 2mm and a sample with the relative permittivity of 2.05 and a thickness of 1mm is estimated with errors less than ±0.5% and ±0.2%, respectively. Moreover, in measuring a sample without displacing the receiving horn antenna to avoid the error in measurement, we derived an expression of the permittivity estimation for S parameters measured using a vector network analyzer, and demonstrated that the measurement of a sample without antenna displacement is valid.
