中波天线小型化的分析和比较

Analysis and comparison of medium wave antenna's miniaturization

针对CFA(交叉场天线),双锥天线两种天线对中波天线小型化进行了讨论和分析,简单介绍了这两种天线的原理,并运用软件对这两种天线作了仿真、比较.根据得到的结果显示CFA天线的原理违背了经典的电磁场理论.而双锥天线不仅符合经典的电磁场理论和天线的设计原理,且也实现了中波天线小型化的设想.

The tradition Medium Wave Antenna need great tract,have more requirements and embarrass- ment when it set up.Designer of antennas want to find a method which can make the medium wave anten- na be much smaller with the tradition medium wave antenna.CFA(Crossing Field Antenna),Double-Cone Antenna gave this method some hope and assistant.This article analyzes and discusses the principle of these two kinds of antenna,then by use of emulate software to calculate and compare.According to the result we have see the Crossing Field Antenna is not conform to the classical electromagnetism theoretic.However Double-Cone Antenna not only conform to the classical electromagnetism theoretic and design principle of antenna,and also made Medium Wave Antenna's Miniaturization be came ture.
