Abstract :
In this paper, a zero index metamaterial lens (ZIML) based on Z-shaped meta-atom is proposed to achieve directive emission. Z-shaped meta-atom is implement as the unit cell of the ZIML to achieve near zero permittivity for wideband. Patch antennas work at, respectively, 7.27 GHz, 8.02 GHz and 9.14GHz are used to test the directivity enhancement of the ZIML. Simulation results demonstrate that the ZIML we designed is able to significantly improve the directivity of the patch antennas.
