摘要
Abstract
The mutual coupling between antennas is an important factor that affects the umbrella an tenna array radiation performance.This paper studies the factors affecting the mutual coupling between umbrella antenna array elements, and establishesa Cutler antenna array modelin the FEKO simulation software. Under non⁃uniform ground conditions, the electrical parametersof Cutler antenna array are calculated under different operating frequencies.In homogeneous groundenvironment,the impedance characteristics of Cutler antenna are calculated under different array element spacings. Thepaper analyzes the mutual coupling effects on radiation performance and the schemethat reduces themutual couplingof VLF trideco umbrella antenna tower array. Considering therestrictionsof actual site conditions,increasing the distanceappropriately can reduce the impactof coupling interference onradiation efficiency.关键词
