A Dual Frequencies and Bidirectional Functional Metasurface for Dual Polarization Beam Convergence
2020 IEEE International Conference on Computational Electromagnetics (ICCEM)(2020)
Abstract
In this paper, a dual frequencies and bidirectional functional metasurface is presented. The functional metasurface can achieve bidirectional radiation with dual polarization at different frequencies. By independently adjusting the reflection and transmission phases, the forward and backward beam convergence can be achieved. The simulated results indicate that the gain of reflection beam can reach 24.9 dBi at 9 GM and the gain of transmission beam can reach 26.1 dBi at 12 GHz, which is at least 13.5 dBi higher than the bare feeder.
