Abstract

Developing reliable standards for coaxial line systems in the AC-RF gap region has long proven to be challenging. In this work, the use of an N-type coaxial air line as an impedance standard at low frequencies is investigated through a comparison of measurements taken on an LCR meter from 0.1 kHz to 1 MHz with calculated values based on transmission line theory. The results demonstrate the viability of using such an air line as an impedance standard at frequencies below 1 MHz.
