    • Decoupling of multifrequency dipole antenna arrays for microwave imaging applications 

      Sáenz Sáinz, Elena Upna; Guven, K.; Ozbay, Ekmel; Ederra Urzainqui, Íñigo Upna; Gonzalo García, Ramón Upna (Hindawi Publishing Corporation, 2010)   Artículo / Artikulua  OpenAccess
      The mutual coupling between elements of a multifrequency dipole antenna array is experimentally investigated by S-parameter measurements and planar near-field scanning of the radiated field. A multifrequency array with ...
    • MIMO based decoupling strategy for grid connected power converters controlled in the synchronous reference frame 

      Samanes Pascual, Javier Upna; Gubía Villabona, Eugenio Upna; López Taberna, Jesús (IEEE, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Power converters are frequently connected to the grid through a LCL filter, controlling its power transfer through a current control loop in the synchronous reference frame. In this reference frame, cross coupling terms ...
    • Study on antenna mutual coupling suppression using integrated metasurface isolator for SAR and MIMO applications 

      Alibakhshikenari, Mohammad; Virdee, Bal S.; See, Chan H.; Abd-Alhameed, Raed; Falcone Lanas, Francisco Javier Upna; Andujar, A.; Anguera, J.; Limiti, Ernesto (IEEE, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      A metasurface based decoupling structure that is composed of a square-wave slot pattern with exaggerated corners that is implemented on a rectangular microstrip provides high-isolation between adjacent patch antennas for ...
