摘要：
In this study, the effect of loading microstrip antenna using epsilon near zero (ENZ) metamaterial is investigated. It is known that ENZ material may help to improve the transmission through a boundary condition and that the scattering parameters may be completely independent of such boundary properties. This idea is demonstrated to significantly increase the bandwidth of a simple rectangular microstrip patch antenna. To realise the ENZ material, a periodic wire medium is designed, simulated, fabricated, and tested. Simulation results based on CST Microwave studio have good agreement with measurements.
