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 ...
Radiation performances of a multifrequency dipole antenna array with a left handed superstrate
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the radiation performances of a multifrequency antenna array (MFAA) which consists of
two dipoles (1 and 3) that are radiating at 9.57 GHz and other one (dipole 2) radiating at 11.98 GHz are
presented. In ...
Radiation performances of a dipole array configuration inserted in a left-handed media
(IEEE, 2005)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the radiation improvements achieved when Left Handed Media (LHM) are combined with dipole antennas has been analysed. The behavior of two dipole antennas in array configuration when a Left Handed superstrate ...
Research on metamaterials for antenna applications
(2005)
Contribución a congreso / Biltzarrerako ekarpena,
During the last 20 years a lot of attention has been paid to apply Electromagnetic Band Gap (EBG) technology
in different frequency ranges, from microwaves to optics. EBG technology is based on the use of periodic structures ...
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 ...
