Abstract

In this study, we describe a circular ring slot antenna with three circular holes, which is supplied by a CPW-fed split ring resonator metamaterial. This proposed antenna covers sophisticated satellite communication applications for wireless devices, including 5G, military, and aerial radar, and resonates between 2.4 GHz and 10.4 GHz, with a center frequency of 3.542 GHz and an S₁₁ of -37.7 dB, and a center frequency of 7.5 GHz and an S₁₁ of -30.4 dB, respectively. The produced antenna satisfactorily validates the specified antenna metrics. The suggested antenna is built on an affordable FR4 substrate and has physical dimensions of 38 × 38 × 1.6 mm³. The proposed simulated design antenna is validated by the measured data. The results show a good correlation between the measured data and the simulation. The operational impedance range of the proposed antenna is less than -10 dB. The circular ring slot antenna has proven to be remarkably capable of reaching multiband frequencies of 3.54 GHz and 7.5 GHz. The proposed antenna may have an effect on radiation characteristics and gain, resulting in a good contender. Each component of the circle-shaped ring slot antenna design is essential to achieving the important and encouraging results.
