A slot antenna has been designed and optimized to obtain frequency reconfigurability over a
wide range of frequencies. The proposed antenna has a rectangular slot with a hexagonal …

A novel multiband fractal wide slot meta material antenna is designed for Bluetooth/WIMAX/
WLAN and X band downlink applications. In order to generate the WLAN (2.4/5.8 GHz) and …

A metamaterial with frequency reconfigurability over a wide range of frequencies is
presented in this paper. The proposed unit-cell has a circular geometrical shape with a triple …

A frequency reconfigurable metamaterial-based microstrip antenna is presented in this
paper. The proposed antenna consists of three split-ring resonators (SRR) and a tapered …

This article consists of an investigation of compact reconfigurable antenna to verify the
possibility of obtaining multiband frequencies. The designed patch antenna has a size of …

In this article an antenna with circular patch and defective ground plane is presented. The
defective ground is achieved through a rectangular slot. This structure has realized …
