The need for high-speed communication has created a way to design THz antennas that operate at high frequencies, speeds, and data rates. In this manuscript, MIMO antenna is designed using metamaterial. two-port proposed uses complementary split-ring resonator patch. results are also compared with simple patch show the improvement. shows better isolation of 50 dB. A broadband width 8.3 achieved ...

in this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. the shape of ring resonator filter adding and dropping that wehave proposed is race track. this filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. transmissionefficien...
