    • Antenna beam steering and beam forming at mm Wave and THz frequencies 

      Vega Piña, Sara (Universitat Politècnica de Catalunya, 2021-01-20)
      Projecte Final de Màster Oficial
      Accés obert
      The evolution of wireless communications and the emergence of novel applications will spur the demand of higher data rates, requiring, on one hand, unallocated spectrum in the millimeter Wave (mm-Wave) and Terahertz (THz) ...

    • Measurement of holographic trap positioning 

      Domínguez Álvarez, Noemí (Universitat Politècnica de Catalunya, 2014-09-09)
      Projecte Final de Màster Oficial
      Accés obert
      [ANGLÈS] Dynamic control and precise optical trap positioning are possible with spatial light modulators in holographic optical tweezers. In this work, we deeply study the error induced in trap positioning by a mismatch ...

    • Orientación de antenas mediante técnicas fotónicas en sistemas inalámbricos de radiofrecuencia 

      Vega Piña, Sara (Universitat Politècnica de Catalunya, 2018-07)
      Treball Final de Grau
      Accés obert
      In recent years, the orientation of antennas (beamsteering) in wireless communication systems has been influenced by the appearance of 5G networks, which work with a wide bandwidth. The limitations of traditional RF signal ...

    • The global navigation satellite systems reflectometry (GNSS-R) microwave interferometric reflectometer: hardware, calibration, and validation experiments 

      Onrubia Ibáñez, Raúl; Pascual Biosca, Daniel; Querol Borràs, Jorge; Hyuk, Park; Camps Carmona, Adriano José (Multidisciplinary Digital Publishing Institute (MDPI), 2019-02-27)
      Article
      Accés obert
      This manuscript describes the Microwave Interferometric Reflectometer (MIR) instrument, a multi-beam dual-band GNSS-Reflectometer with beam-steering capabilities built to assess the performance of a PAssive Reflectrometry ...
