Metamaterials as super-substrate to enhance dipole antenna performances
(2004)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, pass band properties of Left Handed Media (LHM) are demonstrated. These properties have been used in order to make a LHM super-substrate that is put over a dipole antenna. This super-substrate is going to ...
High efficient dipole antennas by using left-handed superstrates
(2004)
Contribución a congreso / Biltzarrerako ekarpena,
This paper deals with pass band properties of Left Handed Media (LHM) to enhance dipole antenna performances. The LHM properties have been used in order to make high directivity antennas with good return loss features. The ...

Using CORPS-BFN to feed multibeam antenna systems
(2007)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a simple example of application of the CORPS-BFN concept has been presented.
A multibeam antenna system is seen as a small part of the human eye, and therefore, improving the similarity of the
whole system ...
Utilizando CORPS-BFN para alimentar sistemas de antenas de múltiples haces
(2007)
Contribución a congreso / Biltzarrerako ekarpena,
This paper present an application of the Coherently
Radiating Periodic Structures - CORPS on the design of a Beam
Forming Network -BFN. The Named CORPS-BFN is a novel
feeding network with special behaviour characteristics ...
Low profile multi-frequency dipole antenna array based on planar meta-surfaces
(IEEE, 2007)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performance of a low profile multi-frequency dipole antenna array with a
planar meta-surface is presented. The meta-surface consists of two closely located parallel grids of short
dipoles and ...
EBG superstrate antenna for WAAS bands
(2008)
Contribución a congreso / Biltzarrerako ekarpena,
Multiband antennas can simplify considerably the complexity of receivers and transmitters,
reducing the size and the mass of the conventional configurations. On the other hand, applications with
high directivity requirements ...
