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 ...
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 ...
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: ...
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 ...
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 ...
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 ...
New approach to the design of corrugated horn antennas
(1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present two new corrugated horn antenna designs in circular waveguide. The first one is a
converter horn antenna from monomode circular waveguide TE11 to corrugated waveguide HE11 mode in a very efficient ...
