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 y medida de una antena choke-gaussiana
(2002)
Contribución a congreso / Biltzarrerako ekarpena,
A new design of corrugated horn antenna for global earth
coverage from a geostationary satellite to obtain very low
sidelobes and crosspolar levels with a really compact design in a
quite wide bandwidth is presented in ...
Comparación entre antenas cónicas corrugadas y antenas gaussianas corrugadas
(2002)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a study of two equal size corrugated horn antennas;
a conical and a gaussian profiled horn antenna (GPHA) has been
developed.
It will be demonstrated that GPHA´s provide lower sidelobes and
wider bandwidths, ...
Ultra-wide band corrugated profiled horn antenna design
(IEEE, 2002)
Artículo / Artikulua,
Nowadays, an increasing number of applications need stable radiation patterns
with low sidelobes and low crosspolar levels in a very wide bandwidth. Gaussian Profiled
Horn Antennas (GPHA’s) have demonstrated its feasibility ...
A novel ku-band circularly-polarized horn antenna based on a ridged wall
(IEEE, 2023)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a novel wideband (31.5 % bandwidth) circularly-polarized antenna based on a ridged wall is presented. A pair of ridges on the inner wall of the horn serves as an inbuilt polarizer, which can generate left-hand ...
Silicon integrated subharmonic mixer on a photonic-crystal platform
(IEEE, 2021)
Artículo / Artikulua,
This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photoniccrystal (PC) slab to a resonant cavity that effectively ...
Design and characterization of terahertz CORPS beam forming networks
(Springer, 2023)
Artículo / Artikulua,
This work reviews the design and applicability of beam-forming networks based on Coherently Radiating Periodic Structures (CORPS-BFN) at Terahertz (THz) frequency bands. These versatile networks offer two operation modes: ...
High-yield waveguide diplexer for low-cost E-band 5G point-to-point radio links
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
This paper presents the design and realization of a high-yield tuning-less waveguide diplexer and a high-gain lens horn antenna for 5G point-to-point fixed-beam communications at the frequency ranges of 71/76 GHz and 81/86 ...
Fully metallic Luneburg metalens antenna in gap waveguide technology at V-band
(IEEE, 2023)
Artículo / Artikulua,
This article presents the design of a flat Luneburg
metalens antenna at V-band using gap waveguide (GW) technology. The metalens consists of a parallel plate waveguide (PPW)
loaded with metallic pins whose height is ...
Very short and efficient feeder design from monomode waveguide
(IEEE, 1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present an original and short corrugated horn antenna
profile to obtain the HE11 corrugated circular waveguide mode exciting with
a pure TE11 monomode smooth circular waveguide mode. We will obtain ...
