Compact bull's-eye antenna in ridge gap waveguide with circular polarization at 60 GHz
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
In this work, a Bull's-Eye (BE) antenna with circular polarization (CP) based on ridge gap waveguide (RGW) technology, working in the millimeter-wave band (60 GHz) is numerically and experimentally demonstrated. The structure ...
Compact antennas in ridge gap waveguide with circular polarization
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this paper, two compact antennas in Ridge Gap Waveguide (RGW) technology, working at 60 GHz, with a high-purity circular polarization (CP) within a broad bandwidth are manufactured and measured. The antennas are fed ...
Performance evaluation of spatial modulation patterns in compressive sensing terahertz imaging
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Terahertz (THz) imaging traditionally uses pixel-to-pixel mechanical raster scanning, which is slow and limits the resolution and potential applications. Compressive Sensing Terahertz (CS-THz) imaging has the potential to ...
Hyperbolic lens antenna in groove gap waveguide technology at sub-millimeter waves
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a flat hyperbolic lens antenna using Groove Gap Waveguide (GGW) technology is designed at 300 GHz. A GGW horn antenna is used to feed the metamaterial lens placed in a parallel plate waveguide (PPW), in order ...
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 ...
Parametric study of pin surface used to suppress undesired modes in a packaged W-band microstrip receiver
(IEEE, 2013)
Contribución a congreso / Biltzarrerako ekarpena,
A pin surface structure has been used in order to
suppress undesired modes in a packaged W-band RF front-end
receiver. A parametric analysis has been carried out in order to
determine the optimum dimensions. Resonances ...
Comparison of a slotted SIW antenna covered with metasurface vs. a traditional array
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this article we compare two solutions to improve the radiation pattern of a slotted Substrate Integrated Waveguide (SIW) antenna: use of an E-plane array and covering it with a metasurface (MTS). To this aim, we compare ...
Análisis de efecto de un superestrato left-handed en la apertura de una guía rectangular
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, results showing the experimental verification of the gain improvement of a rectangular waveguide antenna when a left-handed material (LHM) is used as superstrate are presented. The improvement has been ...
Radiation performances of a multifrequency dipole antenna array with a left handed superstrate
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performances of a multifrequency antenna array (MFAA) which consists of
two dipoles (1 and 3) that are radiating at 9.57 GHz and other one (dipole 2) radiating at 11.98 GHz are
presented. In ...
Radiation performances of a dipole array configuration inserted in a left-handed media
(IEEE, 2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the radiation improvements achieved when Left Handed Media (LHM) are combined with dipole antennas has been analysed. The behavior of two dipole antennas in array configuration when a Left Handed superstrate ...
