Abstract Empty coaxial structures built with printed circuit boards have low radiation, low losses, high quality factor and non‐dispersive features. The full integration of empty substrate‐integrated coaxial line (ESICL) in a planar substrate is nowadays a fact thanks to a grounded coplanar transition. To properly characterize and measure this new ESICL family of devices, a low cost and easy to manufacture thru‐reflect‐line calibration kit is proposed to de‐embed not only the connectors and feeding lines, but also the ESICL transitions.
