The broadband sensors are fabricated using microsystems technology and are used between 1 and 35 GHz. A calibration method to determine the sample permittivity is adapted. The sensors are intended for the non-invasive characterization of biological cells. Saline solutions, water, and an ethanol-water mixture are used to experimentally verify the functionality of the sensors for this purpose. The simulated sensitivity of a quasi-lumped sensor is shown to be up to seven times higher than that of a conventional coplanar waveguide sensor. This hints at the miniaturization potential of these sensors.enbiosensorsmicrosensorsMicrowave sensorsConference Paper10.1109/EuMC.2014.6986527Other
