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 ...
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 ...
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: ...
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 ...
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 ...
The Canfranc Axion Detection Experiment (CADEx): search for axions at 90 GHz with Kinetic Inductance Detectors
(IOP Publishing, 2022)
Artículo / Artikulua,
We propose a novel experiment, the Canfranc Axion Detection Experiment (CADEx), to probe dark matter axions with masses in the range 330–460 μeV, within the W-band (80–110 GHz), an unexplored parameter space in the ...
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 ...
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 ...
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 ...
New coplanar waveguide based on the gap waveguide technology
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
A new planar waveguide, coined Inverted coplanar gap waveguide is presented. The concept of gap waveguides and parallel plate suppression between perfect magnetic and a perfect electric conductors is applied to coplanar ...
