Simulations of A Quasi-Yagi Planar Antenna Working in 3GH

The planar microstrip-fed quasi-yagi antenna has shown excellent radiation characteristics over a wide frequency band. In this paper, a quasi-yagi planar antenna working in 3GH is described. The radiation characteristics of this antenna are very good, with a front-to-back ratio 18db and cross polarization level -18db.These performances have been confirmed by FTDT simulations.
