Minimizing phase error in dual-polarization synthetic-aperture-based millimeter-wave OTA measurements

The data included here is for the phase error calculations for different VNA calibrations without and with relaxation of the RX cable. We show that the phase errors reduce significantly in the latter case. This dataset is for our paper that will appear in the 107th ARFTG Microwave Measurement Conference (ARFTG = The Automatic Radio Frequency Techniques Group) taking place on 12 June 2026 in Boston, MA.
