In this paper Split Ring Resonators are designed at two different frequencies and SRR are merged with monopole antenna designed at 3GHz. This antenna shape looks like a weapon bludgeon hence it is named as square shape bludgeon antenna. The said antenna gives four different bands in the UWB range. Both the antennas can be used for WLAN and WiMAX applications as it covers both the frequencies. The complementary Split Ring Resonators are etched at ground surface to enhance the Bandwidth of antenna, and bandwidth enhancement is achieved at higher frequency. The metamaterial property of SRR is proved in first section of paper. The fabricated antennas tested using the vector network analyzer, the measured and simulated results are in good agreement with each other.
