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 ...
Experimental validation of a Ku-band dual circularly polarized metasurface antenna
(IEEE, 2018)
Artículo / Artikulua,
The experimental validation of a Ku-band dual circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single layer MTS has been synthesised employing sub-wavelength ...
Photonic-assisted 2-D terahertz beam steering enabled by a LWA array monolithically integrated with a BFN
(Optica, 2022)
Artículo / Artikulua,
A novel photonic-assisted 2-D Terahertz beam steering chip using only two tuning
elements is presented. The chip is based on an array of three leaky wave antennas (LWAs) with
a monolithically integrated beamforming network ...

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 ...
Evanescently fed electromagnetic band-gap horn antennas and arrays
(IEEE, 2012)
Artículo / Artikulua,
The design of a horn antenna based on electromagnetic band-gap structures (EBGs) and fed by evanescent fields in the containing periodic structure is presented. Such all-dielectric antennas can form compact arrays and ...
All-metallic ε-near-zero (ENZ) lens based on ultra-narrow hollow rectangular waveguides: experimental results
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Here we perform numerical and experimental investigation of plano-concave all-metallic ε-near-zero (ENZ) lens with operational frequency f = 144 GHz. The ENZ lens is achieved by stacking an array of narrow hollow rectangular ...
Experimental study of the antenna influence in RTLS based-on RFID
(IEEE, 2012)
Contribución a congreso / Biltzarrerako ekarpena,
Nowadays Real-time localization systems (RTLS)
are growing up very quickly but there are some remaining
issues which need to be analyzed. This paper presents an
experimental study that shows how different kind of antennas
can ...
