A 1-to-8 GHz Miniaturized Dielectric Spectroscopy System for Chemical Sensing Conference Paper

abstract

• This paper presents a miniaturized broadband dielectric spectroscopy system for dielectric characterization and chemical sensing for 1-to-8 GHz frequency range. Sensor operation is based on detecting the phase shift of a signal passing through a true-time-delay (TTD) cell at the presence of an organic chemical. Cascaded TTD cells are used to improve the detection accuracy and the sensing bandwidth. Measurements with calibration show accurate detection of frequency-dependent permittivity for organic chemicals with permittivities up to 20. 2012 IEEE.
