3D-printed 96 GHz bull’s-eye antenna with off-axis beaming
Beaskoetxea Gartzia, Unai ; Maci, Stefano; Navarro Cía, Miguel ; Beruete Díaz, Miguel (IEEE, 2017) Artículo / ArtikuluaReducing the profile, footprint and weight of antennas embarked on aircrafts, drones or satellites has been a long pursued objective. Here we tackle this issue by developing a millimeter-wave 96 GHz elliptical Bull’s-Eye ... -
77-GHz high-gain bull’s-eye antenna with sinusoidal profile
Beaskoetxea Gartzia, Unai ; Pacheco-Peña, Víctor ; Orazbayev, Bakhtiyar ; Akalin, Tahsin; Maci, Stefano; Navarro Cía, Miguel (IEEE, 2015) Artículo / ArtikuluaA high-gain Bull’s-Eye leaky-wave horn antenna working at 77 GHz with sinusoidal profile has been designed, fabricated, and experimentally measured. The influence of the number of periods on the gain and beamwidth is ... -
Dual circularly polarized broadside beam metasurface antenna
Ederra Urzainqui, Íñigo ; Tellechea Pereda, Amagoia ; Caminita, Francesco; Martini, Enrica; Iriarte Galarregui, Juan Carlos ; Gonzalo García, Ramón ; Maci, Stefano (IEEE, 2016) Artículo / ArtikuluaThis paper presents the design of a modulated metasurface (MTS) antenna capable to provide both righthand (RH) and left-hand (LH) circularly polarized (CP) boresight radiation at Ku-band (13.5 GHz). This antenna is based ... -
Experimental demonstration of metamaterials application for mitigating scan blindness in phased array antennas
Rodríguez Ulibarri, Pablo ; Crépin, Thomas; Martel, Cédric; Boust, Fabrice; Falcone Lanas, Francisco Javier ; Loecker, Claudius; Herbertz, Kai; Bertuch, Thomas; Dousset, Thierry; Martinaud, Jean-Paul; Maci, Stefano; Marcotegui, José Antonio ; Beruete Díaz, Miguel (EDP Sciences, 2016) Artículo / ArtikuluaThis paper presents two metamaterial-inspired solutions to mitigate the scan blindness effects in a phased array antenna. In the first solution, portions of a bed of nails are introduced in the radome to prevent the excitation ... -
Experimental validation of a Ku-band dual circularly polarized metasurface antenna
Tellechea Pereda, Amagoia ; Caminita, Francesco; Martini, Enrica; Ederra Urzainqui, Íñigo ; Teniente Vallinas, Jorge ; Iriarte Galarregui, Juan Carlos ; Gonzalo García, Ramón ; Maci, Stefano (IEEE, 2018) Artículo / ArtikuluaThe experimental validation of a Ku-band dual circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single layer MTS has been synthesised employing sub-wavelength ...
