摘要
考虑到船用棒状天线的窄波段局限性,设计一种简易船用可调式倒L单极天线,以满足宽频段的正常通信,进行天线结构设计及机理分析;分析天线结构参数对天线特性的影响;分析接地材料及馈点高度影响下的天线地面效应;运用ANZYS HFSS电磁仿真软件对天线进行结构优化并标定天线基本参数。结果表明,该倒L天线依据参数标定表可以有效满足整个VHF(30～300 MHz)频段的要求。
Due to the drawback of the narrow-band characteristics of the marine rod antenna,a simple marine adjustable inverted-L monopole antenna was designed to meet the normal communication in a wide frequency band.The antenna structure was design.The influence of structural parameters upon the antenna characteristics was analyzed,as well as the ground effect of antenna under the influence of grounding materials and feed height.The electromagnetic simulation software ANZYS HFSS was used to optimize the antenna structure and calibrate the basic parameters.The results showed that the designed inverted-L antenna can effectively meet the requirements of entire VHF(30-300MHz)frequency band according to the parameter calibration table.
