Análisis del comportamiento de esquemas de modulación adaptativos en LTE
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the behaviour of several modulation
schemes used in 3GPP R8 or Long Term Evolution (LTE)
Systems is analyzed. In order to increase the capacity of future
mobile networks, high order modulation schemes like ...
Comportamiento de propagacion electromagnetica en el apilamiento de agujeros sublambda y agujeros propagantes
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, we provide more insight on the physics
underlying the transmission through subwavelength hole arrays
metaprism by comparing it with propagating hole arrays prism.
We show the critical role that the size ...
All-metallic ε-near-zero (ENZ) lens based on ultra-narrow hollow rectangular waveguides: experimental results
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Here we perform numerical and experimental investigation of plano-concave all-metallic ε-near-zero (ENZ) lens with operational frequency f = 144 GHz. The ENZ lens is achieved by stacking an array of narrow hollow rectangular ...

A new waveguide slot array antenna with high isolation and high antenna bandwidth operation on Ku- and K- Bands for radar and MIMO systems
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
In this paper a novel technique is proposed to reduce the mutual coupling between the radiating elements of a waveguide slot array antenna. This is achieved by inserting slots between the waveguide oval shaped slots. The ...
Study on antenna mutual coupling suppression using integrated metasurface isolator for SAR and MIMO applications
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
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 ...
Mutual-coupling reduction in metamaterial substrate integrated waveguide slotted antenna arrays using metal fence isolators for SAR and MIMO applications
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
A new type of mutual coupling reduction technique is applied to metamaterial substrate integrated waveguide (SIW) slotted antenna array. The circular shaped reference SIW antenna array is constructed from Alumina substrate ...
