Abstract : Numerous writers have hinted at the necessity for broader bandwidth coverage of microwave frequency communication employing tiny antennas, and various solutions have been put forth. This study presents a metamaterial-based microstrip triple band antenna with operating frequencies of 2.4 GHz, 3.5 GHz, and 5 GHz proposed for X-band fifth generation (5G) application. A metamaterial-based microstrip antenna with integrated square complementary split ring resonators (CSRR) was designed, simulated, and analyzed. The design of microstrip patch was done using transmission line equations, and analysis was done using full wave model with the aid of Computer Simulation Technology (CST) Studio software. Flame Resistant (FR-4) substrate with a dielectric constant of 4.2 and thickness of 1.6 mm was chosen mainly for maintaining compact antenna geometry. Bandwidths of 820 MHz, 1600 MHz, and 800 MHz were achieved at 2.4 GHz, 3.5 GHz, and 6 GHz by the proposed metamaterial-based antenna. The proposed antenna also showed good potential as it resonated equally at higher frequencies beyond 12.7 GHz, broadening its application horizon. Regarding the proposed antenna's bandwidth performance, it is recommended to be utilized for devices that are not as compact yet require a wide range of frequency coverage.
