Abstract

A new ultrawideband (UWB) sensor for microwave imaging and sensing is introduced. The structure consists of a dielectric loaded Vivaldi radiating element encapsulated into a cylindrical waveguide. Its length and diameter are 95 and 25.4 mm, respectively. Electromagnetic energy is coupled into the human body by direct contact between the aperture and skin, while the rest of the sensor structure is fully shielded. The sensor shows ability to transmit and receive electromagnetic energy from 1.8 to 12 GHz.
