This paper presents the Dual-band microstrip patch antenna integrated with a rectangular split-ring resonator (R-SRR) metasurface is proposed for 5G-NR Applications. 5G NR applications include mmwave for the short distance line of sight communications. The short distance communications demand the compact devices including compact antennas. A metasurface loaded rectangular patch antenna is designed using an FR4-epoxy (εr = 4.4) substrate. In the proposed design, the R-SRR metasurface is placed 1 mm above a rectangular patch antenna to enhance performance. The modified antenna operates at two distinct frequency bands, (22.5-23.7 GHz) and (27.4-28.6 GHz). The metasurface integration in a simple rectangular patch antenna results in improved gain from 2.42 dB to 6.59 dB. Simulations are performed using ANSYS HFSS V 25.0, and key performance parameters, including return loss, radiation pattern, and gain, are analyzed. This antenna design is optimized for 5G networks, ensuring high speed and low-latency communication. As part of this work, the proposed patch antenna was fabricated on an FR4 substrate to initiate the process of experimental validation. |
