Next generation of connected and autonomous vehicles will be equipped with high numbers of antennas operatingin a wide frequency range for communications and sensing the environment. The study of the 3D spatial angularresponses and radiation pattern modified by the vehicular structure will allow a better integration of communicationand sensing antennas. The use of near-field monostatic focusing technique, jointly with frequency-dimension scaletranslation is applied for imaging using the concept of differential imaging to obtain the differential currents. Theaim of this paper is to research the capability of obtaining the induced currents using near-field monostatic focusingsystem, from an analytical and experimental point of view. Measurements, using reference target, were performedin terahertz band, from 220 to 330 GHz. The results show that the induced currents are estimated using thismethodology and the influence of the bandwidth is assessed.
