Abstract EN
In the last few years, there has been growing interest in employing metamaterials (MTMs) to enhance antenna gain.
In this paper we proposed a novel structure of planar folded-line left-handed metamaterial (FL-LHM) and applied it to improve the gain of three 5.8 GHz microstrip antenna types: a circularly polarized patch antenna, an antenna array, and a beam steering antenna.
The planar FL-LHM structure was designed based on transmission line analysis.
Their scattering parameters were obtained using a numerical model; the negative effective permittivity and permeability were then calculated from these parameters for the assessment of negative refraction index region.
The S11 and radiation patterns of three fabricated antennas were measured; these results matched well with the simulation.
We observed that the gain was increased up to 3 dBi for all the antennas.
In addition, we were also able to maintain the circular polarization as well as the steering of the antenna without changing its dimensions.
