Abstract

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-LC (ELC) element. By employing these structures, three frequency bands of 2.49 ~ 2.55, 3.0 ~ 3.68, and 5.03 ~ 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 ~ 2.53 GHz, together with an ultrawideband of 2.95 ~ 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.
