Zigbee radio channel analysis in a complex vehicular environment [wireless corner]
Rajo-Iglesias, Eva; López Iturri, Peio
; Aguirre Gallego, Erik ; Azpilicueta Fernández de las Heras, Leyre ; Gárate, Uxue; Falcone Lanas, Francisco (IEEE, 2014)
Artículo / Artikulua 
In this paper, the influence of topology and morphology of a particularly complex scenario for the deployment of ZigBee wireless sensor networks is analyzed. This complex scenario is a car. The existence of loss mechanisms ... -
Zoned fishnet lens antenna with reference phase for side lobe reduction
Pacheco-Peña, Víctor ; Navarro Cía, Miguel ; Orazbayev, Bakhtiyar ; Minin, Igor V.; Minin, Oleg V.; Beruete Díaz, Miguel (IEEE, 2015)
Artículo / Artikulua
Reduction of first side lobe level and nulls in artificial fishnet metalenses is accomplished here by applying the reference phase concept along with the zoning technique. Higher focusing efficiency is achieved for a ... -
Zoned near-zero refractive index fishnet lens antenna: steering millimeter waves
Pacheco-Peña, Víctor ; Orazbayev, Bakhtiyar ; Beaskoetxea Gartzia, Unai ; Beruete Díaz, Miguel ; Navarro Cía, Miguel (AIP Publishing, 2014)
Artículo / Artikulua
A zoned fishnet metamaterial lens is designed, fabricated, and experimentally demonstrated at millimeter wavelengths to work as a negative near-zero refractive index lens suitable for compact lens antenna configurations. ... -
ε-near-zero (ENZ) graded index quasi-optical devices: steering and splitting millimeter waves
Pacheco-Peña, Víctor ; Torres Landívar, Víctor ; Beruete Díaz, Miguel ; Navarro Cía, Miguel ; Engheta, Nader (IOP Publishing, 2014)
Artículo / Artikulua
Graded index ε near-zero (GRIN-ENZ) quasi-optical components such as beam steerers and power splitters are designed, simulated and analyzed. The GRIN-ENZ medium is realized using stacked narrow hollow waveguides whose ...
