Abstract :
This paper presents work on a CPW liquid sensor realized in LTCC technology. Challenges of using the sensor at millimeter wave frequencies are discussed. A solution is proposed to obtain measurements with higher accuracy. Measurements of water-methanol mixtures agree well with theoretical models up to 110 GHz, showing the sensor´s potential of cell-solution sensing at millimeter wave frequencies.
