Abstract :
We find that using metamaterial antenna radome made by 90 degree rotational symmetric unit cell structure can enhance the gain of dual-polarized antenna. The Jerusalem cross structure is proposed for dual-polarized antenna radome and its refraction index is designed to be near zero. This radome is designed for the WiMAX applications. Simulation results show that this antenna radome can improve the gain of dual-polarized patch antenna.
