A new hilbert structure based meta-surface for improving isolation between two antenna elements

A new Hilbert structure based EM meta-surface operated in 800–1000 MHz, is firstly presented in this paper for improving the isolation and radiation performance of a two-element antenna array. To verify the validity of our design, both the simulation and measurement are then carried out. Finally, their well-agreed results show that the isolation is increased by 5dB without degrading their radiating performance, making the design a good candidate for car wireless system applications.
