An improved ultra-wideband (UWB) and high gain rectangular microstrip antenna is specifically designed in this paper using planar metamaterial based on double-ring resonators (DRR). The antenna has three double-ring resonators (DRRs) etched on the metal patch, and a partial ground plane so that the impedance matching characteristics of the antenna are much better. The -10 dB impedance bandwidth of the proposed antenna is 2.33-16.96 GHz. The antenna is promising for many applications such as WiMAX (2500-2690 MHz), Bluetooth (2400-2480 MHz) and UWB (3.1-10.7 GHz) applications. In addition, the proposed antenna has an average gain of 4.24 dB and a peak gain of 6.87 dB at 12.2 GHz.
