In the paper, a new technique for building a multi-band antenna array with rectangular split-ring resonators (SRRs) is described. The antenna's analysis and design are studied using simulations. On a low-cost FR4 substrate with a total area of 31,84 × 26,06 mm2, the antenna is mounted. The antenna array based on SRR exhibits three-band resonances with good gain characteristics. The simulations focus on calculating resonance frequencies, return loss, and radiation patterns in order to confirm the practicality and applicability of the proposed antenna concept. The Method of Moments (MOM) in Advanced Design System (ADS) software serves as the basis for the electromagnetic solution used in these simulations. Working inside the 3.5 GHz, 4 GHz, and 4.22 GHz bands. a verified S11 value of less than -10 dB suggests that the impedance matching of this antenna is adequate. It offers gains for the appropriate 6.6 dBi, 7.20 dBi, and 6.3 dBi frequency ranges. The antenna is compatible with WLAN (Wireless Local Area Network) 5G (fifth-generation technology standard for cellular networks), LTE (Long Term Evolution), and WiMAX (Worldwide Interoperability for Microwave Access: wireless broadband communication standards based on the IEEE 802.16 well suited for rural areas) wireless network systems, particularly those operating in the sub-6 GHz band. Some of the main features of this antenna are its symmetric radiation patterns, modest size, planar design, and stable gain. These characteristics make it a viable choice for modern S-band microwave wireless communication applications, especially for gadgets that run at frequencies lower than 6 GHz.
