摘　　要：本文提出一个甚高频抗重影电视接收天线方案。以二频道为例，分析了小尺寸八木天线前后比Ｆ／Ｂ的窄带性及展宽频带的方法。合理地配置Ｆ／Ｂ，实现抗重影性能。This paper proposes an arrangement of very high frequency antighost TV receiving antenna.With TV channel 2 as example,narrow performance of small size Yagi antenna front-to-back ratio F/B and method used to expand the F/B bandwidth has been analyzed. By distributing the F/B bandwidth reasonably,the antighost ability can be realized.
