A novel design method for phase-locked loops of any order and type
(IEEE, 2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a novel approach to the design of PLLs is
presented, which can be used regardless of their Order and Type.
The method stems from the fact that high-frequency poles in the
loop filter determine filtering ...
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 ...
Design of a planar meta-surface based on dipoles and wires for antenna applications
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the design of a planar meta-surface based
on dipoles and wires is presented. The unit cell is formed
by three independent layers, which contain two parallel
dipoles and one wire. The behaviour of these ...
Study of the human eye working principle: an impressive high angular resolution system with simple array detectors
(IEEE, 2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper the working principle of the human
eye is studied since uses very simple detectors, cones
and rods, to provide an impressive high angular
resolution without using any kind of scanning
technique. Usually ...
Diseño de alimentadores optimizados para la cámara anecoica de la Universidad de Limoges
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, high technology optimized feed horn designs are presented. These feed horns have been designed to improve the quite zone size and behaviour of the CATR of the CREAPE research team at Limoges University. Very ...
Optimized feedhorn designs for compact antenna test range at Limoges University
(IEEE, 2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, high technology optimized feedhorn
designs are presented. These feedhorns have been
designed to improve the quite zone size and behaviour
at the Compact Antenna Test Range (CATR) of the
Antenna Research ...
Boresight radiation of a dipole antenna with a uniform or non-uniform left handed superstrate
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper measurements of the radiation performances of a dipole fed by a coaxial balun and a dipole with a
left handed superstrate based on a finite periodic repetition of a unit cell are compared. Two types ...
Enhancement of the power radiated by a dipole antenna at boresight by means of a left handed superstrate
(IEEE, 2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a comparison between the measured radiation performances of a single dipole and a dipole with
a left handed superstrate based on a finite periodic repetition of a unit cell is presented. First of all the ...
A general beam-forming network made with CORPS
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
A new beam-forming network concept is
introduced. This network is based in the design principles of
CORPS. The new proposed structure presents an
improvement in design over the traditional beam-forming
network since, ...
Designing feeding networks with CORPS: coherently radiating periodic structures
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
The design of feeding networks in phased array systems results tricky since all the complex excitations should be
provided to all the radiating elements of the system. Where the number of radiating elements increases the ...
