摘　　要：甚低频天线一般是工作于该频段的电小天线,且其辐射效率不高,为了满足远距离的通信要求,天线往往采用多组天线的方式来保证足够大的功率容量,因此,多组天线的同步调谐就至关重要,本文对多组天线多调谐方式进行了研究,并对其互耦效应及调谐过程进行了理论分析,并借助数值仿真计算对简化的多调谐山谷天线进行了计算验证,得到了一致的结果,为后续多调谐天线研究应用提供了参考。VLF antennas are generally the small electric antennas that work in this frequency band,and their radiation efficiency is not high.In order to meet the requirements of long-distance communication,antennas often use multiple sets of antennas to ensure sufficient power capacity.Therefore,multiple sets of antennas synchronous tuning are very important.The multi-tuning method of multiple antennas is studied and the mutual coupling effect and tuning process are theoretically analyzed in the paper.The simplified multi-tuning valley antenna is verified by numerical simulation calculation,and consistent results have been obtained.This method can be provided a reference for the subsequent research and application of multi-tuned antennas.
