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 ...
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 ...
Análisis de efecto de un superestrato left-handed en la apertura de una guía rectangular
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, results showing the experimental verification of the gain improvement of a rectangular waveguide antenna when a left-handed material (LHM) is used as superstrate are presented. The improvement has been ...
Radiation performances of a multifrequency dipole antenna array with a left handed superstrate
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performances of a multifrequency antenna array (MFAA) which consists of
two dipoles (1 and 3) that are radiating at 9.57 GHz and other one (dipole 2) radiating at 11.98 GHz are
presented. In ...
Radiation performances of a dipole array configuration inserted in a left-handed media
(IEEE, 2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the radiation improvements achieved when Left Handed Media (LHM) are combined with dipole antennas has been analysed. The behavior of two dipole antennas in array configuration when a Left Handed superstrate ...
Research on metamaterials for antenna applications
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
During the last 20 years a lot of attention has been paid to apply Electromagnetic Band Gap (EBG) technology
in different frequency ranges, from microwaves to optics. EBG technology is based on the use of periodic structures ...
Design of a multifrequency antenna array with the use of left-handed superstrates
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performances of different antenna configuration
based on Left-Handed superstrates are presented. First of all, the behaviour of a Left-
Handed (LH) unit cell is analysed, showing a resonant ...
Low profile multi-frequency dipole antenna array based on planar meta-surfaces
(IEEE, 2007)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performance of a low profile multi-frequency dipole antenna array with a
planar meta-surface is presented. The meta-surface consists of two closely located parallel grids of short
dipoles and ...
