Design of new MeTaMaterial (MTM) traveling-wave antenna with "D-formed" left-handed structure is proposed. The proposed MTM structure is designed at a height of 0.8mm from the ground plane with almost 2GHz bandwidth. The most interesting feature of the design is the ability of enhancing the gain and total efficiency of the antenna without negative effects of the other important parameters like bandwidth. By using the "D-shaped" MTM structure and printed planar technique, the bandwidth of the MTM traveling-wave antenna is significantly increased at a resonant frequency of 6GHz and also a foot print area reduction of the antenna structure is provided.
