Simple modelling of DGS to design 1D-PBG low-pass filters
(Wiley, 2003)
Artículo / Artikulua,
The use of defected ground structures (DGS) is being intensively explored by the microwave filter designer community. The DGSs are one possible implementation of a 1D Photonic Band Gap (1D-PBG) where some defect structures ...
A stopband filter design using a 1-D non-periodic defected ground structure
(Wiley, 2003)
Artículo / Artikulua,
The one-dimensional (1-D) defected ground structure is used to control the cutoff frequency characteristic. In this paper three non-periodic filters are built, in order to show the versatility of the DGS. Five unit cells ...
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 ...
