Abstract
A multiband antenna is proposed in this paper, accomplished with a split ring resonator (SRR) in the ground plane for portable and wireless applications. The rectangular radiator is unified with a semi-circular stub improving the impedance matching in the antenna. Further, the radiator creates an optimized rectangular slot to obtain the multiband operation. The SRR in the ground plane demonstrates the metamaterial (MTM) characteristics that significantly improve the 10 dB impedance bandwidths (IBW) and enhance realized gain in the multi-band antenna. The proposed antenna is procuring the five 10 dB IBW, which can be prominent for RADAR (2.96 GHz - 3.06 GHz), 5G (3.92 GHz - 4.32 GHz and 4.64 GHz - 5.04 GHz), WLAN (5.32 GHz - 5.64 GHz) and ISM band (5.7 GHz - 6 GHz) applications. The gain enhancement is obtained in all operating bands of the antenna, and a maximum 5.24 dB gain is achieved at a 4.14 GHz frequency.
