| 摘 要： | 基于复合左/右手传输线(compositeright/left-handed transmission line,CRLH)理论,设计了供船舶救险报警系统用的、可工作于1.6GHz和2.4GHz的双频小型化EPIRB(emergency position indicating radio beacon,EPIRB)天线,对所设计天线进行了数学仿真.仿真结果证明,天线符合相关国家和国际标准,并且该天线相对于现有的鞭状EPIRB天线具有结构尺寸小、低剖面、易于制备和易集成等优点.天线能工作于2.4GHz频段,可用于近距离通信,扩展了天线的使用范围,为新型EPIRB天线设计提供了新思路.

| Abstract: | Based on the composite right/left-handed transmission line （CRLH） theory, this paper designs a dual-band small emergency position Indicating radio beacon （EPIRB） antenna used in the alarm recovery system for vessels, which can work both in 1.6GHz and 2.4GHz frequency bands. The mathematical simulation results show the antenna satisfies relevant Chinese national and international standards, and has the advantage of the structure of small size, low profile, easy preparation and integration relative to the current whip antenna EPIRB. The antenna which can work in the 2.4GHz frequency band can be used for short distance communication, so the application range of the antenna is extended, providing a new idea for the design of EPIRB antenna. |
