A user-centric privacy framework for pervasive environments
(Springer, 2006)
Contribución a congreso / Biltzarrerako ekarpena,
One inherent feature of pervasive computing environments is the need
to gather and process context information about real persons. Unfortunately, this
unavoidably affects persons¿ privacy to a large degree. Each time ...
Diseño de filtros en guía rectangular usando estructuras PBG's
(2000)
Contribución a congreso / Biltzarrerako ekarpena,
A new application of dielectric periodic
structures (also known as PBG) to build and design
waveguide filters is presented. The periodic
structures have some stop frequency bands, band
gaps, defined by the geometry, ...
Diseño de filtros banda rechazada usando Defected Ground Structures (DGS)
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a type of Defected Ground Structure (DGS) is studied and used to implement filters in microstrip technology. It is first demonstrated that the main parameter which controls its operation is the external ...
Diseño de filtros paso bajo usando Defected Ground Structures (DGS)
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a new method of trully design of filters using Defected Ground Structures is proposed. It makes use of the model proposed in previous developments by the same authors and simplifies it to a first-order model ...
Diseño y medida de una antena choke-gaussiana
(2002)
Contribución a congreso / Biltzarrerako ekarpena,
A new design of corrugated horn antenna for global earth
coverage from a geostationary satellite to obtain very low
sidelobes and crosspolar levels with a really compact design in a
quite wide bandwidth is presented in ...
Estudio de resonancias parásitas en antenas corrugadas
(2001)
Contribución a congreso / Biltzarrerako ekarpena,
A theoretical study reinforced with practical measurements about
the origin of the return loss spikes in corrugated horn antennas is
presented in this paper. These spikes are directly related to the
periodic structure ...
Antena corrugada con perfil gaussiano de gran ancho de banda
(2001)
Contribución a congreso / Biltzarrerako ekarpena,
En este trabajo se presenta el diseño de una antena de bocina
corrugada con más de un 40% de ancho de banda. Los patrones
de radiación medidos coinciden muy bien con los simulados.
Esta antena se puede usar en aplicaciones ...
Ultra-wide band corrugated gaussian profiled horn antenna design
(IEEE, 2001)
Contribución a congreso / Biltzarrerako ekarpena,
A corrugated horn antenna design with more than 40% bandwidth is
proposed in this paper. The measured radiated field patterns have a good
agreement with the simulated ones.
This antenna can be used in applications that ...
Comparación entre antenas cónicas corrugadas y antenas gaussianas corrugadas
(2002)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a study of two equal size corrugated horn antennas;
a conical and a gaussian profiled horn antenna (GPHA) has been
developed.
It will be demonstrated that GPHA´s provide lower sidelobes and
wider bandwidths, ...
Conical versus gaussian profiled corrugated horn antennas
(IEEE, 2002)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a study of two equal size corrugated horn antennas; a conical
and a gaussian profiled horn antenna (GPHA) has been developed.
It will be demonstrated that GPHA´s provide lower sidelobes and wider ...
