Modern corrugated horn antenna design for extremely low sidelobe level
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
The present paper deals with the design of modern corrugated horn antennas for extremely low sidelobe level with the
use of the well known corrugated Gaussian Profiled Horn Antenna aperture (corrugated GPHA’s) to improve ...
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 ...
Choked-gaussian corrugated horn antenna design small global coverage horn antenna for TT&C with extremely low sidelobe level
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
Extremely low sidelobe horn antennas are often required for the actual technology. This type of horn antennas are
important to avoid interference with other systems.
In this paper we describe a new design implementing a ...
Diseño de una antena dual gaussiana de doble profundidad de corrugación
(2003)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a new design of a dual-band corrugated horn antenna is presented. The design is based on a gaussian profile to allow high pattern symmetry, low-crosspolar levels and low-side-lobes over a wide frequency range. ...
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 ...
Glottal spectrum based inverse filtering
(ISCA, 2003)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a new inverse filtering technique for the time-domain estimation of the glottal excitation is presented. This approach uses the DAP modeling for the vocal tract characterization, and a spectral model for the ...
Unified analysis of glottal source spectrum
(ISCA, 2003)
Contribución a congreso / Biltzarrerako ekarpena,
The spectral study of the glottal excitation has traditionally
been based on a single time-domain mathematical model of
the signal, and the spectral dependence on its time domain
parameters. Opposite to this approach, ...
