摘　　要：提出了一种工作于30MHz~8400MHz频段的适合旋翼无人机载环境的小型化复合全向天线。该天线集成了30MHz~600MHz、600MHz~8400MHz两段天线,并通过共用安装底板共口径输出。通过合理的天线结构设计,一方面获得了较高的低端增益,另一方面解决了高端天线不圆度过大的问题,也使得天线具有更好的适装性。该复合天线外层为低端天线(30MHz~600MHz),采用不对称偶极子天线形式,内层为高端天线单元(600MHz~8400MHz),采用双锥天线形式。设计时将馈电走线及支撑结构作为天线的一部分,较大程度地改善了天线不圆度。A miniaturized omnidirectional composite antenna for UAV-mounted application is proposed in this paper,which works from 30 MHz to 8400MHz.There are two bands antennas,30-600MHz and 600-8400MHz,integrated in this composite antenna with the same plate.Through reasonable antenna structure de-sign,on the one hand,a higher gain is obtained at low frequency,on the other hand,the performance of round-ness at high frequency band is improved also,and the antenna has better adaptability.A asymmetric dipole an-tenna(from 30 to 600MHz)is in the outer layer,and a biconical antenna is in the inner layer.Setting the feed-ing track and supporting structure as a part of the antenna can greatly improve the roundness of the antenna.
