Abstract This paper introduces a novel reconfigurable superstrate using a band-stop frequency selective surface (FSS) based on four arms star geometry. The proposed reconfigurable superstrate is applied to a dipole antenna for use in 5G NR technology with a frequency of 3.545 GHz. The study includes both simulated and experimental results which confirm the redirection of the antenna radiation pattern. The developed structure exhibits radiation in only one half-space, high polarization isolation, and a redirection of the radiation pattern up to ±55°. The ideal cases were considered, where the ON and OFF states of the diodes were replaced by short circuits and gaps, respectively. Overall, the results demonstrate the effectiveness of the proposed FSS as a promising solution for 5G NR technology applications. |
