Calibration Laboratory of Schmid & Partner Engineering AG Zeughausstrasse 43, 8004 Zurich, Switzerland References [1] IEC106 WG10 draft report, February 2017 Methods Applied and Interpretation of Parameters: • Coordinate System: z-axis in the waveguide horn boresight, x-axis is in the direction of the E-field, y- axis normal to the others in the field scanning plane parallel to the horn flare and horn flange. • Measurement Conditions: The forward power to the horn antenna is measured prior and after the measurement with a power sensor. During the measurements, the horn is directly mounted to the waveguide source. Absorbers are used around the horn, in the boresight axis and at the back connector. • Horn Positioning: The waveguide horn is mounted vertically on the flange of the waveguide source to allow vertical positioning of the EUmmW probe during the scan. The plane is parallel to the phantom surface. Probe distance is verified using mechanical gauges positioned on the flare of the horn. • E- field distribution: E field is measured in the x-y-plane with a vectorial E-field probe with the source power of typ. 20 dBm at < 50 GHz and 10 dBm at > 50 GHz. The probe sensor center is 10 mm (in z) above the flare frame of the waveguide horn in the near field. The E-field value stated as calibration value represents the E-field-maxima 10mm in front of the horn. • E-field polarization: Above the open horn, linear polarization of the field is expected. This is verified graphically in the field representation. 1. Measurement Conditions DASY system configuration, as far as not given on page 1.

The scan area was 30 mm x 16 mm with a resolution of 1.0 mm at a sensor distance of 10.0 mm from the front of the horn. The maxima at this distance are observed along the line of the E-field polarization (short dimension of the horn flare). Additional plots were required to see the Field variation within the plot; they are scaled to the overall maximum.
