A wideband microwave system for head imaging is presented. The system includes an array of 16 corrugated tapered slot antennas that are installed on an adjustable platform. A switching device is used to enable the antennas to sequentially send a wideband 1–4 GHz microwave signal and capture the backscattered signals. Those signals are recorded using suitably designed virtual instrument software architecture...
This paper reports the design of a directive antenna for ultra-wideband microwave imaging systems. The antenna is a corrugated tapered slot antenna of compact dimensions (22 mm × 40 mm) immersed in a coupling liquid that is fabricated to improve the matching between the antenna and the imaged object, and thus to increase the dynamic range of the imaging system. The antenna is covered with a dielectric...
