Estado del arte de las antenas que combinan corrugaciones horizontales y verticales
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In the present paper the state of the art, possibilities, advantages and disadvantages of the patented corrugated horn antennas that combine horizontal and vertical corrugations is being covered. These rather new type and ...
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 ...
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 ...
Resultados experimentales de la mejora de potencia radiada por un dipolo mediante un superstrato left-handed
(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 left handed superstrate based on a finite periodic repetition of a unit cell is presented. First of all the ...
Dipolos y metamateriales: mejora de las características de radiación
(2004)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, pass band properties of Left Handed Media (LHM) are demonstrated. These properties have been used in order to make a LHM super-substrate that is put over a dipole antenna. This super-substrate is going to ...

High efficient dipole antennas by using left-handed superstrates
(2004)
Contribución a congreso / Biltzarrerako ekarpena,
This paper deals with pass band properties of Left Handed Media (LHM) to enhance dipole antenna performances. The LHM properties have been used in order to make high directivity antennas with good return loss features. The ...
