On-Demand Frequency Reconfigurable Flexible Antenna for 5Gsub-6-GHz and ISM Band Applications

This paper presents the design and characterization of on-demand frequency reconfigurable antenna for 5Gsub-6-GHz and ISM-band applications. The antenna comprises of compact overall size having dimensions of 0.23λ0 × 0.2λ0 × 0.002λ0. The octagonal patch was loaded with stub to enhance bandwidth along with improvement in return loss, afterword a slot and diode was utilized to achieve frequency reconfigurability. The numerical analysis of the proposed antenna was done using Higher Frequency Structural Simulator (HFSS). Furthermore, to demonstrate the potential of the proposed work it is compared with state of the art works for similar applications.
