A Metamaterial Inspired Antenna for Sub 6GHZ 5G Application

The study examines a small, low-profile, metamaterial inspired antenna for sub-6 GHz 5G applications that is loaded with a circular complementary split ring resonator (C-CSRR) based on negative permittivity and permeability. Two popular frequency bands, n78 5G NR and n79 5G NR (2.78–7.03) GHz, are produced by adding metamaterial to the radiator. The corresponding gains are 6.24 dB and 5.3 dB. The design is able to achieve high impedance bandwidth of 4.25 GHz from 2.78GHz to 7.03GHz with high return loss (S11 <-37 dB). The antenna offers simulated radiation efficiency of 96.09% at 3.5 GHz and 93.41% at 6.45 GHz making it suitable for 5G communication demands. The antenna constructed on a FR-4 substrate with a dielectric constant of 4.4 and measures just 28 x 28 x 1.6 mm3. HFSS simulation software is being put into use to design, model, and measure the suggested antenna parameters in a real-world environment. The simulated outcome demonstrates that the suggested metamaterial antenna's peak gain is around 6dB to 7 dB and it has a resonance frequency for C-band applications, including weather radar systems and 5G applications.
