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 ...
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 ...
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 ...
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 ...
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 ...
On the determination of the phase center of gaussian horn antennas
(1998)
Contribución a congreso / Biltzarrerako ekarpena,
Gaussian horn antenna designs have experimentally demonstrated excellent performance to produce a very pure Gaussian beam mode with extremely low sidelobes and crosspolarization levels. These results make very attractive ...
Gaussian profiled horn antennas
(1999)
Contribución a congreso / Biltzarrerako ekarpena,
In many different applications parameters
such efficiency, gain, directivity, etc., are really
critical. By using the Gaussian techniques presented
here, the radiating features of existing horn antenna
systems can be ...
Generation of the HE11 mode in rectangular waveguide using gaussian techniques
(IEEE, 1999)
Contribución a congreso / Biltzarrerako ekarpena,
A new and efficient design of a rectangular corrugated waveguide mode converter,
from TE10 mode in a smooth rectangular monomode waveguide to HE11 mode in a
corrugated rectangular waveguide, is proposed. The main idea ...
Estudio de resonancias parásitas en antenas corrugadas
(2001)
Contribución a congreso / Biltzarrerako ekarpena,
A theoretical study reinforced with practical measurements about
the origin of the return loss spikes in corrugated horn antennas is
presented in this paper. These spikes are directly related to the
periodic structure ...
Antena corrugada con perfil gaussiano de gran ancho de banda
(2001)
Contribución a congreso / Biltzarrerako ekarpena,
En este trabajo se presenta el diseño de una antena de bocina
corrugada con más de un 40% de ancho de banda. Los patrones
de radiación medidos coinciden muy bien con los simulados.
Esta antena se puede usar en aplicaciones ...
