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 ...
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 ...
Corrugated horn antenna noise temperature characterisation for the NRL water vapor millimeter-wave spectrometer project
(2011)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper the antenna noise temperature for two different corrugated horn antennas (old model and new model) for NRL WVMS is being characterized. The whole optical system will be simulated with Ticra’s
GRASP software, ...
Suberb gaussian beam efficiency corrugated horn antennas
(2010)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper we are presenting the possibilities of
corrugated horn antennas that combine horizontal and
vertical corrugations.
EBG superstrate antenna for WAAS bands
(2008)
Contribución a congreso / Biltzarrerako ekarpena,
Multiband antennas can simplify considerably the complexity of receivers and transmitters,
reducing the size and the mass of the conventional configurations. On the other hand, applications with
high directivity requirements ...
On the determination of the phase center of gaussian horn antennas
(1998)
Contribución a congreso / Biltzarrerako ekarpena,
Gaussian horn antenna designs have experimentally demonstrated excellent performance to produce a very pure Gaussian beam mode with extremely low sidelobes and crosspolarization levels. These results make very attractive ...
Gaussian profiled horn antennas
(1999)
Contribución a congreso / Biltzarrerako ekarpena,
In many different applications parameters
such efficiency, gain, directivity, etc., are really
critical. By using the Gaussian techniques presented
here, the radiating features of existing horn antenna
systems can be ...
Generation of the HE11 mode in rectangular waveguide using gaussian techniques
(IEEE, 1999)
Contribución a congreso / Biltzarrerako ekarpena,
A new and efficient design of a rectangular corrugated waveguide mode converter,
from TE10 mode in a smooth rectangular monomode waveguide to HE11 mode in a
corrugated rectangular waveguide, is proposed. The main idea ...
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 ...
