An analytical method to implement high-sensitivity transmission line differential sensors for dielectric constant measurements / Muñoz Enano, Jonathan (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; Vélez Rasero, Paris (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; Gil Barba, Marta (Universidad Politécnica de Madrid. Departamento de Ingeniería Audiovisual y Comunicaciones) ; Martín, Ferran (Martín Antolín) (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica)
A simple analytical method useful to optimize the sensitivity in differential sensors based on a pair of meandered microstrip lines is presented in this paper. Sensing is based on the phase difference of the transmission coefficients of both lines, when such lines are asymmetrically loaded. [...]

2 p, 1.1 MB Angular displacement and velocity sensors based on electric-LC (ELC) loaded microstrip lines / Naqui Garolera, Jordi (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; Martín, Ferran, (Martín Antolín) (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica)
Planar microwave angular displacement and angular velocity sensors implemented in microstrip technology are proposed. The transducer element is a circularly shaped divider/combiner, whereas the sensing element is an electricLC resonator, attached to the rotating object and magnetically coupled to the circular (active) region of the transducer.
