TLDR
In this article, the authors investigated slot technique and metamaterial superstrate to enhance antenna bandwidth and gain, the gain has been improved by around 4 dB and the antenna including metammaterial shows a by 25 % wider bandwidth.Abstract:
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.read more
