A compact monopole antenna on a printed circuit board incorporating a single negative (SNG) metamaterial targets application in the X and Ku bands at 9.2 and 14.2 GHz. The design utilizes circular split-ring resonator (SRR) unit cells, structured with periodic arrangements smaller than the guided wavelength. Using CST Studio Suite simulation, the antenna demonstrates a wide 750 MHz bandwidth and very low radiation losses. This efficient design enhances performance and coverage, making it well-suited for radar and satellite communications within the targeted frequency bands.
