高频宽带可调交叉场天线的实验研究

Experimental investigation of tunable HF crossed-field antenna

首先对交叉场天线CFA(crossedfieldantenna)的结构、工作原理进行了简要介绍,然后给出了一个λ/60～λ/40宽带可调高频交叉场天线的实验结果.实验结果表明交叉场天线是极小尺寸的电小天线,但该天线的性能指标不受惠勒、朱兰臣、哈林顿的“传统”电小天线理论的限制,而应该有相应的“非传统”电小天线的理论.

This paper gives a brief introduction to the structure and operating principles of CFA(crossed field antenna),and then offers the results of experiments on one λ/60-λ/40 tunable HF CFA .The result shows CFA is a very small, broadband and highly efficient electrically small antenna, and its performance parameters are not limited by“traditional” electrically small antenna theory founded by Wheeler,Chu and Harrington.The“untraditional” electrically small antenna theory should be established to explain the CFA.
