Silicone-Carbon-Based Phantom for Nearfield Characterization of Wearable Antennas at 60 GHz

This paper evaluates a solid silicone-carbon-based phantom for nearfield antenna characterization at millimeter-wave (mmW) frequencies.Unlike conventional phantoms designed to mimic permittivity, this phantom is optimized to replicate the skins reflectivity.Numerical simulations compare the phantoms response to a homogeneous skin model, focusing on S 11 , radiation efficiency, total efficiency, and radiation patterns for a patch antenna operating at 60 GHz.The results indicate a strong agreement between the phantom and skin models, with mean absolute errors below 1 dB.These findings validate the phantoms applicability for wearable antenna testing, offering a reliable experimental model for near-body electromagnetic (EM) interaction studies.
