UWB MST MEMS-based near-field imaging system

This paper has discussed and characterized a complete system for UWB imaging. The system has utilized conformed Vivaldi geometries for the illuminator and collector antennas, and a MEMS switched disc dipole as the probe. An imaging algorithm has been presented for a linear transmission imaging architecture. A complete experimental validation has been done for the Vivaldi antennas, probe antenna and switching MST technique. Preliminary results have been obtained for a point-like object, which has shown good results in accordance with UWB resolution capabilities.
