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 ...
Soret fishnet metalens antenna
(Springer Nature, 2015)
info:eu-repo/semantics/article,
At the expense of frequency narrowing, binary amplitude-only diffractive optical elements emulate refractive
lenses without the need of large profiles. Unfortunately, they also present larger Fresnel reflection loss ...
ASTRA 3B horn antenna design
(2010)
Contribución a congreso / Biltzarrerako ekarpena,
The ASTRA 3B satellite includes 60 Ku-band state-of-the-
art transponders and 4 Ka-band transponders. The
spacecraft have been designed for the distribution of
both direct-to-home (DTH) broadcast services and two way
broadband ...
Suberb gaussian beam efficiency corrugated horn antennas
(2010)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper we are presenting the possibilities of
corrugated horn antennas that combine horizontal and
vertical corrugations.
Corrugated horn antenna noise temperature characterisation for the NRL water vapor millimeter-wave spectrometer project
(2011)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper the antenna noise temperature for two different corrugated horn antennas (old model and new model) for NRL WVMS is being characterized. The whole optical system will be simulated with Ticra’s
GRASP software, ...

Advanced feeds for mm-wave antenna systems
(Springer, 2018)
info:eu-repo/semantics/bookPart,
Millimeter-wave antenna systems have traditionally required high performance feeds in order to fulfill its stringent requirements. Therefore, this goal has been achieved by corrugated horns. However, in the last years new ...
Experimental demonstration of a millimeter-wave metallic ENZ lens based on the energy squeezing principle
(IEEE, 2015)
info:eu-repo/semantics/article,
The performance of an epsilon-near zero (ENZ) plano-concave lens is experimentally demonstrated and verified at the D-band of the millimeter-waves. The lens is comprised of an array of narrow metallic waveguides near cut-off ...
