© 2017 IEEE. A 3-10 GHz contactless sensor for liquid and solid material sensing is proposed. The sensor setup is based on utilizing two printed UWB Vivaldi antennas coupled to each other at their radiative near-field region with the material-under-test (MUT) placed in the middle. The sensor setup is fabricated with an overall size of 15:6×6:1 cm2. Liquid chemical detection, and thickness sensing of thin dielectric slabs are successfully carried out using the proposed contactless sensor as a proof of concept.
