摘要
分支笼天线是短波天线中一种常用的天线,具有通信距离远、带宽较宽等特点。舰载分支笼天线在使用过程中会经常受到风荷、冲击、振动等复杂载荷的影响,要求天线结构具有较高安全性及可靠性,因此从天线结构形式、选材、抗风能力计算等方面都对天线结构设计工作起到至关重要的作用。本文根据舰载天线的使用要求,在舰载分支笼天线结构设计的理论计算基础上,详细介绍了一种舰载短波分支笼天线的结构设计思路及天线具体结构形式,并对该天线在实际最大风速下的抗风能力进行了仿真分析,为同类天线的设计提供了依据。
Branch cage antenna is a common antenna in shortwave antenna,which has the characteristics of long communication distance and wide bandwidth.The ship borne branch cage antenna is often affected by wind load,impact,vibration and other complex loads in the use process,which requires the antenna structure to have high safety and reliability.Therefore,the antenna structure design work plays an important role in the aspects of antenna structure form,material selection,wind resistance calculation,etc.According to the operational requirements of the shipborne antenna,based on the theoretical calculation of the structural design of the shipborne branch cage antenna,this paper introduces in detail the structural design idea and the specif ic structural form of the shipborne short wave branch cage antenna,and makes a simulation analysis of the wind resistance of the antenna under the actual maximum wind speed,which provides a basis for the design of similar antennas.
