Abstract :
A differential transmission line sensor at 100 GHz is designed and analyzed. Artificial transmission lines are used in a coplanar waveguide configuration. Its high sensitivity to dielectric changes in thin layers enables detection of DNA hybridization or antibody-antigene binding processes for biomedical applications. It is simple, cheap and easy to combine with semiconductor mm-Wave sources and detectors.
