Two novel metamaterial antennas applied for WLAN and WiMAX are proposed in this letter. Antenna 1 is composed of a monopole radiator with an electric-(ELC) element. By employing these structures, three frequency bands of 2.49 similar to 2.55, 3.0 similar to 3.68, and 5.03 similar to 6.04 GHz are achieved. Each band is well matched and can be easily adjusted. Antenna 2 is integrating with EBG structure, which has a good impedance matching in 2.49 similar to 2.53 GHz, together with an ultrawideband of 2.95 similar to 6.07 GHz. Both antennas have operational bands covering WiMAX in 2.5/3.5/5.5-GHz and WLAN in 5.2/5.8-GHz, omnidirectional radiation patterns over the operating bands. The proposed antennas have the advantages of simple fabrication, miniaturization, and compactness, which can be applied to wireless mobile communication system.
