Schematic of the developed ultra-wideband millimeter-wave imaging system for real-time, in-vivo skin cancer imaging, achieving an overall synthetic bandwidth of 98Â GHz. At each scanning step, two sub-band antennas are placed in front of the target, transmit their signals in their respective sub-band frequency ranges, and record the backscattered signals.
