具有陷波特性的无人船双频段盘锥天线设计

设计了一款适用于应急救援无人船平台的双频段盘锥天线。对传统盘锥天线进行了伞骨化改造并加载了匹配小铜片，实现了天线陷波并减小了风阻。利用HFSS软件对天线进行仿真并实际制作和测量了天线。测量结果表明：天线在应急救援的350MHz和850MHz频段上驻波比均小于1.4，辐射方向均为水平全向，增益最高分别达到4.12dB和6.2dB。在易产生干扰的370MHz-850MHz频段上，驻波基本高于1.5，实现了陷波。所设计的天线满足应急救援无人船平台对天线的要求。

Design of unmanned ship dual-band discone antenna with Band-notched

This paper presents a dual-band discone antenna suitable for unmanned ship platform. Transform the traditional discone antenna to umbrella ossification and load matching small copper to achieve the band-notched and reduces drag. Using HFSS software to simulation and actually production and physical measurements the antenna, measured results agree well with the simulation. Measurement results show that: the VSWR of antenna in the 350MHz and 850MHz, band of emergency rescue less than 1.4, and radiation levels are omnidirectional, gain maximum respectively 4.12dB and 6.2dB. Easy on interfering in the 370MHz-850MHz band, standing basic than 1.5, to achieve a notch, to alleviate the pressure filter station antenna backend. The antenna is designed to meet unmanned boat platform at water rescue and other emergency communications support in the antenna requirements.
