    • Design of beam-forming networks for scannable multi-beam antenna arrays using CORPS 

      Panduro, Marco A.; Río Bocio, Carlos del Upna (EMW Publishing, 2008)   Artículo / Artikulua  OpenAccess
      This paper deals with the design of beam-forming networks (BFN) for scannable multibeam antenna arrays using Coherently Radiating Periodic Structures (CORPS). This design of CORPS-BFN considers the optimization of the ...
    • Design of concentric ring antenna arrays for isoflux radiation in GEO satellites 

      Reyna, Alberto; Panduro, Marco A.; Río Bocio, Carlos del Upna (Institute of Electronics, Information and Communication Engineers (IEICE), 2011)   Artículo / Artikulua  OpenAccess
      The design of concentric rings arrays for isoflux radiation is reported in this paper. This design considers the reduction of the side lobe level and the isoflux radiation requirements for Geostationary Earth Orbit (GEO) ...
    • Design of UAVs-based 3D antenna arrays for a maximum performance in terms of directivity and SLL 

      Garza, Jesús; Panduro, Marco A.; Reyna, Alberto; Romero, Gerardo; Río Bocio, Carlos del Upna (Hindawi, 2016)   Artículo / Artikulua  OpenAccess
      This paper presents a design of UAVs-based 3D antenna arrays for a maximum performance in terms of directivity and side lobe level (SLL). This paper illustrates how to model the UAVs formation flight using 3D nonuniform ...
    • Resolution capabilities of future THz cameras 

      Lizarraga Cubillos, Juan Camilo Upna; Río Bocio, Carlos del Upna (Radioengineering Society, 2011)   Artículo / Artikulua  OpenAccess
      THz technology for developing imaging systems has recently aroused great interest, mainly due to the large number of applications in which these frequencies can be used: security, vision in hard environments, etc. In ...
    • Simple modelling of DGS to design 1D-PBG low-pass filters 

      Garde Irigoyen, Ieltxu Aitor Upna; Yábar, Miguel Javier; Río Bocio, Carlos del Upna (Wiley, 2003)   Artículo / Artikulua  OpenAccess
      The use of defected ground structures (DGS) is being intensively explored by the microwave filter designer community. The DGSs are one possible implementation of a 1D Photonic Band Gap (1D-PBG) where some defect structures ...
    • Simplifying the feeding network for multi-beam circular antenna arrays by using corps 

      Panduro, Marco A.; Río Bocio, Carlos del Upna (EMW Publishing, 2011)   Artículo / Artikulua  OpenAccess
      An innovative way to analyze the design of beam-forming networks (BFN) for scannable multi-beam circular antenna arrays using the CORPS (Coherently Radiating Periodic Structures) concept is introduced. This design of ...
    • A stopband filter design using a 1-D non-periodic defected ground structure 

      Garde Irigoyen, Ieltxu Aitor Upna; Río Bocio, Carlos del Upna (Wiley, 2003)   Artículo / Artikulua  OpenAccess
      The one-dimensional (1-D) defected ground structure is used to control the cutoff frequency characteristic. In this paper three non-periodic filters are built, in order to show the versatility of the DGS. Five unit cells ...
    • Synthesis of volumetric ring antenna array for terrestrial coverage pattern 

      Reyna, Alberto; Panduro, Marco A.; Río Bocio, Carlos del Upna (Hindawi, 2014)   Artículo / Artikulua  OpenAccess
      This paper presents a synthesis of a volumetric ring antenna array for a terrestrial coverage pattern. This synthesis regards the spacing among the rings on the planes X -Y, the positions of the rings on the plane X -Z, ...
    • Ultra-wide band corrugated profiled horn antenna design 

      Teniente Vallinas, Jorge Upna; Gonzalo García, Ramón Upna; Río Bocio, Carlos del Upna (IEEE, 2002)   Artículo / Artikulua  OpenAccess
      Nowadays, an increasing number of applications need stable radiation patterns with low sidelobes and low crosspolar levels in a very wide bandwidth. Gaussian Profiled Horn Antennas (GPHA’s) have demonstrated its feasibility ...
