Mejora de antenas metalo-dieléctricas en la banda de frecuencias GSM-UMTS mediante elementos en transmisión extraordinaria
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work a dual band GSM/UMTS antenna is
proposed. The antenna is based on a stacked planar structure,
where the combination of collimation by Enhanced
Transmission and the use of parasitic director elements is ...
Implementacion de línea de ε negativa en tecnología stripline
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, a negative-ε equivalent response
medium is proponed in stripline technology. To achieve band
rejection behaviour, Complementary Split Ring Resonators
(CSRR) are placed in the central conductor strip of ...
Evalución de dosimetría de campos electromagnéticos en el entorno interior doméstico
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the evaluation of radiofrequency
exposure in a domestic environment is analyzed. 3D raytracing
simulation results are compared with dossimetry measurement
results in a probe household in a dense urban area ...
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 ...
