Abstract

A new design of dual-band antenna for DCS/ PCS/ UMTS/ WLAN/ WiMAX applications is proposed. Using two metamaterials omega-shaped structures, a good impedance matching the dual-band mode is obtained. The proposed prototype antenna is fabricated on a 1.5mm thick FR4 epoxy substrate with a relative dielectric permittivity ε_r= 4.4, and loss tangent tanσ = 0.02. Good monopole-like radiation patterns and antenna gains over the operating bands have also been observed. Effects of each omega particle on the antenna performance and their coupling are all examined and discussed.
