One-dimension metamaterials is instead of the reflector and directors of the Yagi-Uda antenna called MYUA (metamaterial-Yagi-Uda antenna). The length of the MYUA is 10% shorter than that of the traditional Yagi-Uda antenna but the peak gain of MYUA is the same as the peak gain of the traditional Yagi-Uda antenna. The MYUA operates at ISM band 2.4 GHz and the overall size is 150 mm × 70 mm × 0.8 mm. This MYUA is compose of one driven, one metamaterial-reflector and some metamaterial-directors. The peak gain of this MYUA are 8 dBi and 10 dBi when the directors are three layers and seven layers. The efficiency is between 70 – 83%.This concept of the design of metamaterial was introduced into design Yagi-Uda antenna in this technique. Metamaterial-reflector/-directors, which are only used fewer unit-cells of the metamaterial, are instead of the reflector/directors of the traditional Yagi-Uda antenna. The length of metamaterial-Yagi-Uda antenna is 10% shorter than that of the traditional Yagi-Uda antenna. The structure of the metamaterial Yagi-Uda antenna is also flat.Metamaterial-Yagi-Uda antenna is one kind of end-fire high gain antennas. They can be applied to the end to end communication system. They also can be used in remote control toys, such as remote control aircraft.
