    • Are space-filling curves efficient small antennas? 

      González Arbesú, José María; Blanch Boris, Sebastián; Romeu Robert, Jordi (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC., 2003-09-30)
      Article
      Open Access
      The performance of space-filling curves used as small antennas is evaluated in terms of quality factor and radiation efficiency. The influence of their topology is also considered. Although the potential use of these ...

    • Concentrated ground plane booster antenna technology for multiband operation in handset devices 

      Picher, Cristina; Anguera Pros, Jaume; Andújar Linares, Aurora; Puente Baliarda, Carles; Bujalance Jurado, Adrián (2014-12-01)
      Article
      Open Access
      The current demand in the handset antenna field requires multiband antennas due to the existence of multiple communication standards and the emergence of new ones. At the same time, antennas with reduced dimensions are ...

      Salat Vilardaga, Marc (Universitat Politècnica de Catalunya, 2020-07-24)
      Master thesis
      Open Access
      Les comunicacions sense fils estan a l'ordre del dia i el número d’aplicacions pel seu ús augmenta cada vegada més. Gran part dels productes electrònics disponibles al mercat estant incorporant comunicacions sense fils per ...

    • GA design of small thin-wire antennas: comparison with Sierpinski-type prefractal antennas 

      Fernández Pantoja, Mario; García Ruíz, Francisco Javier; Rubio Bretones, Amelia C.; González García, S.; Gómez Martín, Rafael A.; González Arbesú, José María; Romeu Robert, Jordi; Rius Casals, Juan Manuel; Werner, P. L.; Werner, Douglas H. (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-06-30)
      Article
      Open Access
      A new set of genetically generated electrically small thin-wire antennas with a better performance than that of several families of Sierpinsky prefractal monopoles of the same electrical size at resonance is presented

    • GA design of wire pre-fractal antennas and comparison with other Euclidean geometries 

      Fernández Pantoja, Mario; García Ruíz, Francisco Javier; Rubio Bretones, Amelia C.; Gómez Martín, Rafael A.; González Arbesú, José María; Romeu Robert, Jordi; Rius Casals, Juan Manuel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC., 2003-11-30)
      Article
      Open Access
      A multi-objective genetic algorithm (GA) has been applied in conjunction with the numerical electromagnetic code (NEC) to the optimization of wire pre-fractal Koch-like antennas in terms of bandwidth, efficiency, and ...

    • Obtaining Earth images via the APT system 

      Perramon Mascaró, Guillem (Universitat Politècnica de Catalunya, 2020-02-24)
      Bachelor thesis
      Restricted access - author's decision
      Aerospace technology has always been linked to the idea that any project related to this field requires an astronomical economic investment. However, there is in fact a series of projects related to the reception of images ...

    • Terahertz antennas with silicon micromachined front-end 

      Chattopadhyay, Goutam; Reck, Theodore; Jung Kubiak, Cecile; Lee, Choonsup; Siles, Jose Vicente; Chahat, Naser; Cooper, Ken; Schlecht, Erich T.; Alonso del Pino, María; Mehdi, Imran (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference report
      Restricted access - publisher's policy
      Increasingly, terahertz systems are being used for multi-pixel receivers for different applications from mapping the star-forming regions of galaxies to stand-off radar imaging. Since microstrip patch antennas are too lossy ...
