Abstract EN
Metamaterial superstrate is a significant method to obtain high directivity of one or a few antennas.
In this paper, the characteristics of directivity enhancement using different metamaterial structures as antenna superstrates, such as electromagnetic bandgap (EBG) structures, frequency selective surface (FSS), and left-handed material (LHM), are unifiedly studied by applying the theory of Fabry-Perot (F-P) resonant cavity.
Focusing on the analysis of reflection phase and magnitude of superstrates in presently proposed designs, the essential reason for high-directivity antenna with different superstrates can be revealed in terms of the F-P resonant theory.
Furthermore, a new design of the optimum reflection coefficient of superstrates for the maximum antenna directivity is proposed and validated.
The optimum location of the LHM superstrate which is based on a refractive lens model can be determined by the F-P resonant distance.
