“…The most appropriate standards for this purpose are usually sections of precision transmission lines. For example, air dielectric coaxial lines have been used as such standards at frequencies up to 65 GHz [5] and sections of air-filled rectangular metallic waveguide have been used at frequencies up to 110 GHz [6]. In both cases, these standards are used in conjunction with the Thru-Reflect-Line (TRL) [7] and Line-Reflect-Line (LRL) [8] calibration techniques to establish measurement traceability for the calibrated VNA.…”

“…For instance, the characterization of coaxial air lines has traditionally been limited to the transmission line part, and reflections at the connectors have not been systematically accounted for-see e.g. [15,16].…”

Scattering parameters are fundamental quantities in radio frequency and microwave metrology. Traceability to SI units for these measurements is established with the help of calculable standards. Progress has been made over recent years in characterizing these standards. Major steps forward have been achieved with advanced modelling of the entire standard, including connector interface and with the use of multivariate uncertainty evaluation, taking correlations fully into account. The improvements have led to more consistent, more accurate measurements.

This paper describes a new type of primary reference standard for coaxial line impedance measurements at millimetre-wave frequencies. The standard can be used to calibrate vector network analysers (VNAs) and other forms of reflection/transmission measuring instrument. The standard is intended for use in the 'small' precision coaxial line sizes-i.e. 1.85 mm and 1 mm. Fabrication and the subsequent use of the standard to calibrate a VNA in the 1.85 mm line size are described. The standard consists of an air dielectric open-circuit offset by a known length of precision coaxial line. This type of device is considered to be a primary reference standard since its electrical characteristics can be predicted from fundamental electromagnetic theory and can be traceable directly to SI base quantities (i.e. the metre and the second).
