Patent ID: 11631927

Abstract:
Various aspects directed towards an integrated transverse electromagnetic (TEM) transmission line structure for probe calibration are disclosed. In one example, the integrated TEM transmission line structure includes a printed circuit board (PCB) and an air-dielectric coplanar waveguide (CPW). For this example, the air-dielectric CPW includes an air trace in a cutout slot of the PCB. In another example, a method is disclosed, which includes forming an air-dielectric CPW on a PCB in which the air-dielectric CPW includes an air trace in a cutout slot of the PCB. In a further example, an integrated TEM transmission line structure includes an air-dielectric CPW with an air trace. For this example, a first connector is electrically coupled to a first end of the air-dielectric CPW, and a second connector is electrically coupled to a second end of the air-dielectric CPW.
