摘要 在传统单极子天线的基础上,采用短路加载的方式设计一种新型的宽带高强度高功率容量的全向天线。对天线辐射体采用短路加载的方式有效降低天线的剖面高度;对天线辐射体增加一系列通孔有效减轻天线重量;将天线辐射体、天线罩进行一体化固化封装有效提高天线的整体强度。综合考虑天线的驻波系数、水平面不圆度、增益和尺寸等因素,确定天线参数并加工实物进行了测试、试验。实测结果表明该天线在100~350 MHz的频段内驻波系数不大于2.2,方位面方向图不圆度优于1.3 dB,功率容量大于2 kW。 Based on the research of traditional monopole antenna,a new design of wideband high strength and big power capacity omni-directional antenna is presented.Using short-circuit add-in,the height of antenna is efficiently reduced;by adding a lot of vias,the weight of antenna is reduced;by using integrated packaging,the strength of the antenna is enhanced.By synthesizing consideration of VSWR,horizontal roundness,gain and size,the parameter of the antenna are confirmed.An antenna is fabricated and tested.The result indicates that the VSWR is less than 2.2 in bandwidth of 100~350 MHz,the horizontal roundness is less than 1.3 dB,the power capacity is more than 2 kW.
