| 摘 要： | 介绍了应用密距原理设计的密距八木天线,采用T形匹配天线来代替传统的用于激励器的折合振子和用于反射器及引向器的半波偶极子,通过减小T形匹配天线之间的距离来实现天线的小型化设计。以中心频率为500 MHz密距八木天线为例,说明了天线的设计过程,设计结果表明,该天线具有较为理想的技术指标,同时,相对于传统的八木天线,该设计使天线尺寸明显减小。

| Abstract: | The application of compact antenna in the design of Yagi antenna is presented.Replacing the folded dipole which works as feeder and dipoles which work as reflector and directors with T-match antennas,the axis size of the antenna is reduced.Benefiting from reducing the distance between T-match antennas,we realize the miniaturization of compact Yagi antenna is realized.As an example,a 500 MHz compact Yagi antenna is designed.The antenna has good radiation properties,and its size is apparently reduced compared... |
