Split ring resonator metamaterial antenna for WiMax/WLAN applications

A split ring resonator metamaterial antenna for WiMax/WLAN applications was proposed in this paper. Antenna 1 takes a spit ring resonator as its radiator fed by a coplanar waveguide (CPW). Antenna 1 covers the frequency range of 1.7-1.8 GHz which is used for WiMax applications. Antenna 2 is further developed, which adds a complementary spit ring resonator on the ground, and the improved design has a good impedance matching and covers the frequency range of 5.8 GHz which is used for WLAN applications. The proposed two metamaterials antennas have the advantages of simple design, miniaturization and compactness, which can be applied to wireless communication system.
