Enhancement of X band planar antenna parameters with zero index metamaterial

Metamaterial superstrate and slotted technique has been shown to affect antenna bandwidth and gain. This project investigated slot technique and metamaterial superstrate. The slot technique was used to enhance antenna bandwidth. Metamaterial superstrate was used to enhance bandwidth and narrow beamwidth. The gain has been improved by around 4 dB. The antenna including metamaterial shows a by 25 % wider bandwidth.
