Abstract

The design techniques of an asymmetric TEM (ATEM) cell for calibrating E/H filed probes are presented in this paper. The authors describe the techniques to obtain not only the arbitrary frequency and second resonant frequency, but also the test space with $\pm$2dB filed uniformity. We could design an ATEM cell that the measured data, electric filed distribution inside the cell, impedance matching and resonant frequencies, agree with the calculated results.

본 논문에서는 전기장 프로브 교정용 비대칭형 TEM cell의 설계과정과 제작결과에 대해 나타내었다. 2cm$\times$2cm인 시험 공간(test space)에서 전자기장의 균일도가 $\pm$2 ㏈내를 유지하면서, 제1공진 주파수는 1.5GHz 이하에서 출현하도록 하고 제2공진 주파수는 약 GHz에서 출현할 수 있도록 제작하였다. 제작 결과 계산된 결과와 실험된 데이터가 일치함을 볼 수가 있었다.
