| 摘 要： | 天线馈线是天线的重要组成部分,天线馈线设计的好坏对天线性能的影响非常大。在分析了造成某工程设计的L/S组合天线方向图畸变的原因之后,应用电磁波在金属导体上传输的趋肤效应和λ/4同轴短路传输线的阻抗特性,巧妙地设计了一种L/S双频段同轴组合馈线。经测试得到的方向图验证了该设计合理且简单有效。

| Abstract: | The antenna feeder is an important part of an antenna.The antenna feeder design has great influence on the antenna performance.This thesis firstly found out the reason of the undesired aberrant pattern of the L/S dual-band antenna,and then presented an innovative antenna feeder of L/S dual-band antenna by applying skin effect and the impedance property of the short-circuited coaxial transmission line.The test results provee that the design is effectual and simple. |
