• Beam Reconfiguration of Linear Arrays Using Parasitic Elements 

      Rodríguez, J. A.; Trastoy, A.; Brégains, Julio; Ares Pena, F. J.; Franceschetti, G. (The Institution of Engineering and Technology, 2006-02-13)
      [Abstrac] An innovative method for linear arrays beam reconfiguration is presented. This pattern reconfigurability is achieved by a mechanical displacement of a parasitic array located in front of an active one. Two worked ...
    • New Toroidal Beam Antennas for WLAN Communications 

      Brégains, Julio; Franceschetti, G.; Roederer, A. G.; Ares Pena, F. J. (Institute of Electrical and Electronics Engineers, 2007-02)
      [Abstract] The design of a number of new antennas that radiate linearly polarized toroidal beams is described. The developed procedures are based on the use of a method of moments commercial software tool. Several numerical ...
    • Synthesis of Multi-Radial Line Antenna for HIPERLAN 

      Brégains, Julio; Ares Pena, F. J.; Franceschetti, G.; Roederer, A. G. (The Institution of Engineering and Technology, 2003-08)
      [Abstract] We present a new antenna concept - the multi-radial travelling wave line antenna - that achieves a broadband conical radiation pattern suitable for use in multiple C-band wireless computer networks.
