| Abstract: | The planar microstrip-fed quasi yagi antenna has shown excellent radiation characteristics over requency 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. |
