    • Advances in Antenna Technology for Wireless Handheld Devices 

      Anguera Pros, Jaume; Andújar Linares, Aurora; Huynh, Minh-Chau; Orlenius, Charlie; Picher, Cristina; Puente Baliarda, Carles (International Journal of Antennas and Propagation. 2013, 2013-01)
      The constant evolution of wireless handheld devices together with the apparition of multiple wireless communication systemsfosters the antenna community to design new radiating and measurements systems ...

    • Análisis y Diseño de Monopolos Acoplados para Dispositivos Móviles Multibanda 

      Risco, Sergi; Anguera Pros, Jaume; Adújar, Aurora; Pérez Jiménez, Antonio; Puente Baliarda, Carles (Actas del XXIII Simposium Nacional de la Unión Científica Internacional de Radio, 2008-09)
      A novel low profile planar antenna is proposed. The antenna presented is a coupled monopole antenna, comprising at least a driven element coupled with one or more parasitic elements. The design proposed ...

    • Design of Dual Band Patch Antennas for Cellular Communications by Genetic Algorithm Optimization 

      Jayasinghe, Jeevani; Uduwawala, Disala; Anguera Pros, Jaume (International Journal of Engineering and Technology, 2012, Vol. 1, 1, 2012)
      Designing multiband antennas with low volume becomes of practical interest for mobile telecommunications. This paper presents the designs of five small dual band patch antennas for GSM 1800 (1710-1880MHz) ...

    • Diseño de antenas multibanda para telefonía móvil mediante la manipulación del plano de masa 

      Picher, Cristina; Anguera Pros, Jaume; Cabedo Ruiz, Arnau; Ribó i Pal, Miquel; Pijoan Vidal, Joan Lluís; Puente, Carlos (2007-09)
      The Ground Plane used in a handset device has a very important role in the behaviour of the antenna. This study consists on a Ground Plane modification in order to enhance bandwidth and design a ...

    • Fuzzy Logic Control for Multiresolutive Adaptive PN Acquisition Scheme in Time-Varying Multipath Ionospheric Channel 

      Alsina Pagès, Rosa Maria; Mateo Segura, Clàudia; Socoró Carrié, Joan Claudi; Bergadà Caramés, Pau (Fuzzy Logic - Controls, Concepts, Theories and Applications, 2012-03)
      Communication with remote places is a challenge often solved using satellites. However, when trying to reach Antarctic stations, this solution suffers from poor visibility range and high operational ...

    • Low Rate High Frequency Data Transmission from Very Remote Sensors 

      Bergadà Caramés, Pau; Alsina Pagès, Rosa Maria; Vilella Parra, Carles; Regué, Joan Ramon (Remote Sensing - Advanced Techniques and Platforms, 2012-06)
      This chapter deals with the difficulties of transmitting data gathered from sensors placedin very remote areas where energy supplies are scarce. The data link is established bymeans of the ionosphere, ...

    • On the behavior of several fitness functions for genetically optimized microstrip antennas 

      Jayasinghe, Jeevani; Anguera Pros, Jaume; Uduwawala, Disala (International Journal of Scientific World, 2015. Vol. 3, 1, 2015)
      Genetic algorithm (GA) is a popular optimization technique used in the design of performance improved microstrip patch antennas (MPAs). The fitness function plays a vital role in the successful application ...
