摘　　要：介绍了一种可工作于0.8～16GHz的超宽带双圆锥全向天线的工作原理、设计参数及其对电性能的影响,给出了该天线工作于X波段的具体结构尺寸以及VSWR、辐射方向图的仿真和测试数据曲线,以及此天线在0.8～16GHz范围内的VSWR的测试数据曲线,并提出了一些设计此天线的关键点。结果表明,此天线具有频带宽、全向均匀性好、增益大、结构简单等优点,可广泛应用于高低功率的雷达、通讯中的全向天线。The operating principle of an ultra-wideband biconical omni-directional antenna operating within 0.8～16GHz is presented in this paper. And its design parameters and influence on the electrical properties are also proposed. The structural size of the antenna operating at X-band and the simulation and test data curves of the VSWR and the radiation pattern are presented. The test data curve of the VSWR of the antenna operating within 0.8～16GHz are also presented, and some key points of antenna design are given. The results show that this antenna possesses the advantages of wide-band, good omni-directional uniformity, high gain and simple structure, and may be widely applied in the omni-directional antennas of high/low power radars and communications.
