60 GHz single-layer slot-array antenna fed by groove gap waveguide
(IEEE, 2019)
info:eu-repo/semantics/article,
A V-band single-layer low-loss slot-array antenna is presented in this letter. Radiating slots are backed by coaxial cavities, which are fed through a groove gap waveguide E-plane corporate feed network. Cavity resonances ...
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 ...
Generación del modo HE11 a partir de una guía circular lisa monomodo
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present an original taper design to obtain the HE11 corrugated circular waveguide
mode exciting with a pure TE11 monomode smooth circular waveguide mode.
The proposed corrugated taper has a longitudinal ...
Diseño óptimo de antenas de bocina multimodo para excitar un haz gaussiano fundamental de alta pureza
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present an original and optimal multimode horn antenna design to excite the
fundamental Gaussian beam from an overmoded waveguide. In particular, we focus the study in overmoded
circular corrugated ...
Optimal horn antenna design to excite high purity gaussian beam using overmoded waveguides
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present an original and optimal multimode horn antenna design to excite the fundamental
Gaussian beam from an overmoded waveguide. In particular, we focus the study in overmoded circular
corrugated ...
Low-sidelobe-level millimeter-wave asymmetric bull's eye antenna with minimal profile feeding
(IEEE, 2024)
Artículo / Artikulua,
Bull’s eye antennas exhibit remarkable directivity
considering their low profile, albeit accompanied by high sidelobes.
This undesirable radiation characteristic is tackled here by reporting a complementary split ring ...
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 ...
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.
ASTRA 3B horn antenna design
(2010)
Contribución a congreso / Biltzarrerako ekarpena,
The ASTRA 3B satellite includes 60 Ku-band state-of-the-
art transponders and 4 Ka-band transponders. The
spacecraft have been designed for the distribution of
both direct-to-home (DTH) broadcast services and two way
broadband ...
