Optimization of SAM Head Phantom for Compact Antenna Test Ranges

Over-the-air (OTA) performance evaluations of devices operating at frequencies greater than 6 GHz are typically performed in the compact antenna test ranges (CATRs) with head and hand phantoms. However, existing specific anthropomorphic mannequin (SAM) head phantoms do not meet the quiet zone and weight restrictions of CATRs. In this study, we investigated the feasibility of reducing the size and weight of the SAM head while keeping the effect on all standard OTA performance parameters minimal, i.e., deviations compared to the full-head phantom less than 60.2 dB.
