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 to concentrate the power radiated by a rectangular
waveguide achieving larger directivities and consequently larger gains. The transmission and

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 to concentrate the power radiated by a rectangular
waveguide achieving larger directivities and consequently larger gains. The transmission and
radiation properties of this metamaterial (MTM) have been measured using a network
analyser and two rectangular waveguides in the X band. Comparing the transmission
parameter S21 with and without the LHM media between the waveguides, an appreciable
improvement in the power received can be observed. [--]
