摘要
如今船舶普遍使用VHF频段进行通信,在进行大量数据传输时,对天线的带宽、驻波信号比、增益等性能需求较高。针对目前市面上船用VHF天线尺寸大、带宽较低、通信效率低等问题,通过ANSYSHFSS软件进行天线设计,在传统套筒天线外侧架设第二层套筒,并在内层套筒中设计接地短路板,同时在天线顶端进行圆盘加载设计。经过仿真结果证明,设计的新型双套筒天线在船舶通信的VHF频段(156~162 MHz)有着良好的驻波信号比以及带宽,能够在船舶VHF频段满足通信需求。
Nowadays,ships generally use VHF band for communication.When meeting a large number of data transmission,the performance requirements of antenna bandwidth,standing wave signal ratio and gain are higher.Aiming at the problems of large size,low bandwidth and low communication efficiency of marine VHF antenna on the market,the antenna is designed by ANSYS HFSS software.The second layer of sleeve is set outside the traditional sleeve antenna,and the grounding short-circuit board is designed in the inner sleeve.At the same time,the disk loading design is carried out at the top of the antenna.The simulation results show that the new dual sleeve antenna has good standing wave signal ratio and bandwidth in the VHF band(156~162 MHz)of ship communication,and can meet the communication requirements in the VHF band of ship communication.
