Estado del arte de las antenas que combinan corrugaciones horizontales y verticales
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In the present paper the state of the art, possibilities, advantages and disadvantages of the patented corrugated horn antennas that combine horizontal and vertical corrugations is being covered. These rather new type and ...
Desfasadores para microstrip empleando metamateriales
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper an application of LH materials at
microwave frequencies (10GHz) is presented. A compact
quarter-wave impedance transformer is proposed using
alternating sections of left handed media (LHM) and
conventional ...
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 ...
Enhanced radiation properties of a rectangular waveguide by means of a left handed media
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the results of experimental investigations to improve the gain between two
antennas by means of a Left Handed Material (LHM) are presented. The basic idea is the use
of a LHM media acting as a resonator ...
Design of a multifrequency antenna array with the use of left-handed superstrates
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performances of different antenna configuration
based on Left-Handed superstrates are presented. First of all, the behaviour of a Left-
Handed (LH) unit cell is analysed, showing a resonant ...
Designing antenna systems with CORPS (coherently radiating periodic structures)
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a new philosophy to design antenna
systems is presented. It is based on the recently
proposed Coherently Radiating Periodic Structures
(CORPS). These structures are essentially a periodic
structure which ...
Introducción de la bocina en el lazo de optimización de sistemas de reflectores
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In the design process of a complete antenna
system based on reflectors, the feed real performance is
usually included once the reflectors have been optimized
with an ideal feed. In this paper, the proposal is to
include ...
A complete optimization-loop, including feeders, of antenna systems based on reflectors
(IEEE, 2005)
Contribución a congreso / Biltzarrerako ekarpena,
In the design process of a complete antenna system based on reflectors, the feed real
performance is usually included once the reflectors have been optimized with an ideal
feed. In this paper, the proposal is to include ...
Transición coaxial a guía doble ridge cargada
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper a new method to design a
transition from coaxial waveguide to a loaded double
ridge waveguide is proposed. This method allows the use
of the large frequency bandwidth ridge waveguides
present. In the ...
Coherently radiating periodic structures (CORPS): a step towards high resolution imaging systems?
(IEEE, 2005)
Contribución a congreso / Biltzarrerako ekarpena,
The coherently radiating periodic
structures (CORPS) uses the existing
mutual coupling between the elements
of an array to spread horizontally and
coherently (in-phase) the complex
amplitudes of each active element ...
