A compact antenna is proposed using planar-patterned metamaterial structures for ultra-wideband applications. This antenna consists of four metamaterial unit cells that simultaneously show both negative permeability and negative permittivity on the triangular patch and three rectangular slots on the partial ground plane fed with a microstrip line. It has a wide bandwidth from 3.07 to 19.91 GHz for...
A printed multi-standard mobile wireless antenna loaded with double-negative metamaterial that achieves an impedance bandwidth of 2.29 GHz (1.66 to 3.95 GHz) and 1.28 GHz (4.45 to 5.73 GHz) is presented. The proposed antenna can operate in the frequency bands of GSM (1800, 1900, 2100), WiMAX (3.2–3.6 GHZ), WLAN, Bluetooth (2.4 GHz) and WLAN (5.47–5.9 GHz). The antenna is assimilated with a semi-circular...
