This paper will propound an antenna covering the range of frequencies from GHz to GHz that includes GHz, GHz, GHz ,and GHz. The developed quasi-Yagi antenna has a simple-low profile and achieves a bandwidth of 48%, a front- to- back ratio of 19 dB, a gain of 6dBi, and an efficiency of better than 78% at . In this paper, the study on effects of parameters of the antenna is also investigated to achieve optimal model. | A planar quasi-yagi for next generation wireless communication systems
