[Abstract]
Phase compensater used positive phase delay of the left-handed materials is presented for adjusting the phase distribution of left-handed transmission line, and this transmission line will be also consist of right-handed materials, for feeding of Linear antenna array, then realize different feeding conditions and achieve different radition characteristics. Phase characteristics of right/ left-handed transmission line model which is unloss in series was analyzed, based on it, linear antenna array model was also established, at last analyze direction characteristics of this model. The result show that the performance of this antenna is absolutely better than ordinary antenna.
