Assessment of LTCC-based dielectric flat lens antennas and switched-beam arrays for future 5G millimeter-wave communication systems
(2017-10-30)
Article
Open AccessIEEE This paper presents design, LTCC fabrication, and full experimental verification of novel dielectric flat lens antennas for future high data rate 5G wireless communication systems in the 60 GHz band. We introduce and ... -
Annual traffic noise levels estimation based on temporal stratification
(2017-10-19)
Article
Restricted access - publisher's policyThis paper proposes a temporal sampling strategy that increases the accuracy of long-term noise level estimation and allows to establish the estimation error according to the number of sampled days. Days of the week are ... -
Versatile and accurate schemes of discretization in the scattering analysis of 2-D composite objects with penetrable or perfectly conducting regions
(2017-05-01)
Article
Open AccessThe method-of-moment discretization of boundary integral equations in the scattering analysis of closed infinitely long (2-D) objects, perfectly conducting (PEC) or penetrable, is traditionally carried out with continuous ... -
GNSS-R altimetry performance analysis for the GEROS experiment on board the international space station
(MDPI AG, 2017-07-06)
Article
Open AccessThe GEROS-ISS (GNSS rEflectometry, Radio Occultation and Scatterometry onboard International Space Station) is an innovative experiment for climate research, proposed in 2011 within a call of the European Space Agency ... -
Error bound of the multilevel adaptive cross approximation (MLACA)
(2016-01)
Article
Open AccessAn error bound of the multilevel adaptive cross approximation (MLACA 1, which is a multilevel version of the adaptive cross approximation-singular value decomposition (ACA-SVD), is rigorously derived. For compressing an ... -
From experimental campaigns to BEC - CP34 salinity products: Tribute to the Contributions of prof. Font to the SMOS Mission
(2016-09-01)
Article
Open AccessThis article summarizes some of the activities in which Jordi Font, research professor and head of the Department of Physical and Technological Oceanography, Institut de Ciències del Mar (CSIC, Spanish National Research ... -
Tangential-normal surface testing for the nonconforming discretization of the electric-field integral equation
(2016-01-12)
Article
Open AccessNonconforming implementations of the electric-field integral equation (EFIE), based on the facet-oriented monopolar-RWG set, impose no continuity constraints in the expansion of the current between adjacent facets. These ... -
High directivity fractal boundary microstrip patch antenna
(Institution of Electrical Engineers, 2000-05)
Article
Open AccessA novel patch antenna with a fractal boundary condition is proposed. Experimental and numerical results corroborate the fact that the fractal characteristic of the perimeter produces localised modes. This property is ... -

(2016-09-01)
Article
Open AccessThis article summarizes some of the activities in which Jordi Font, research professor and head of the Department of Physical and Technological Oceanography, Institut de Ciències del Mar (CSIC, Spanish National Research ... -
Design of single shaped reflector antennas for synthesis of shaped contour beams using genetic algorithms
(2000-12)
Article
Restricted access - publisher's policyA genetic algorithm (GA) has been developed for designing single-shaped reflector antennas for the synthesis of shaped contour beams. The graphical processing technique is used in order to obtain the antenna radiation ... -
The Koch monopole: a small fractal antenna
(2000-11)
Article
Open AccessFractal objects have some unique geometrical properties. One of them is the possibility to enclose in a finite area an infinitely long curve. The resulting curve is highly convoluted being nowhere differentiable. One such ... -
Dual band fss with fractal elements
(Institution of Electrical Engineers, 1999-04)
Article
Open AccessExperimental and computed results of a frequency selective surface (FSS) based on a certain type of fractal element are presented. The fractal element is a two iteration Sierpinski gasket dipole. Owing to the dual band ...
