16 p, 3.8 MB Strategies to enhance the data density in synchronous electromagnetic encoders / Paredes, Ferran (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; Karami-Horestani, Amirhossein (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; Martín, Ferran (Martín Antolín) (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica)
In this paper, we report two different strategies to enhance the data density in electromagnetic encoders with synchronous reading. One approach uses a periodic chain of rectangular metallic patches (clock chain) that determines the encoder velocity, and dictates the instants of time for retrieving the bits of the identification (ID) code.

5 p, 676.5 KB Enhancing the Per-Unit-Length Data Density in Near-Field Chipless-RFID Systems With Sequential Bit Reading / Havlíček, Jaroslav (Czech Technical University in Prague. Department of Electromagnetic Field) ; Herrojo, Cristian (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; Paredes, Ferran (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica) ; Mata Contreras, Francisco Javier (Universidad de Málaga. Departamento de Ingeniería de Comunicaciones) ; Martín, Ferran (Universitat Autònoma de Barcelona. Departament d'Enginyeria Electrònica)
In this letter, a novel near-field chipless-Radio Frequency Identification (RFID) system with sequential bit reading is reported. The main novelty concerns the tags, implemented by means of straight half-wavelength resonators separated by a small distance and forming a linear chain in the direction orthogonal to their axis.
