Plasmonics Antenna Design Using a Metamaterial-Based Resonating Structure With I-Shaped Ground for 5G Communication

Researchers are looking into radio frequency bands that can adapt to the ever-intensifying requirements of cellular data users due to the exponential growth of wireless data transmission. Plasmonic MIMO antenna helps in the wireless framework and must be verb cultivated and implemented to meet the increasing demands for enriching data rate. The designed plasmonic antenna represents the two-port MIMO antenna geometry structure. The substrate material used to fabricate is FR4 epoxy material which makes it low cost. This material is low in cost, and it is commercially accessible. The operating frequency of the manuscript antenna is 1.31 GHz to 1.91 GHz, 3.21 GHz to 4.81 GHz, and 8.91 GHz to 9.61 GHz. The varying sizes of the I-ground region and radiation elements reveal the structure’s optimization. Isolation improvement of the antenna is noticeable by changing the breadth and longitude of the I-shaped ground. The most noteworthy isolation is getting more prominent than 20 dB, and the ECC esteem is around 0.05 for the introduced antenna. The simulated and measured consequences are correlated to establish the structure’s authenticity. Radiation pattern, antenna gain, directivity, normalized directivity, isolation, and crucial parametric analysis of the antenna are measured. This plasmonic MIMO antenna is admissible for divergent applications like 5G and WLAN communications.
