Abstract :
In this letter we have applied a new anisotropic zero index metamaterial (ZIM) structure to the quasi-Yagi antenna to achieve a high-directivity quasi-Yagi antenna. Simulation results show that the antenna gain increases for a frequency range over which the proposed metamaterial structure exhibits ZIM properties (10.3-11.7 GHz).
