Abstract :
In this paper, we propose a slim printed Yagi antenna. The length of the proposed antenna is reduced by 43% compared with a typical dipole antenna applying the meander structure. In addition, the spacing between the antenna and the reflector is designed as 0.01lambda. A folded dipole and a lumped balun transformer were adopted to compensate the low radiation resistance caused by the reduced spacing. Finally, the performance of the proposed antenna was verified through application on vehicle GPS systems (1.575GHz).
