摘　　要：为满足无人机载天线的宽波束低剖面使用需求,设计制作了一种新型宽波束低剖面无人机机载共形天线。该天线采用新型的L形单极子结构,实现了机载天线的低剖面要求;通过加载短路探针实现了阻抗匹配和垂直极化工作。设计制作的天线在水平面内准全向辐射,在垂直面内3 dB波束宽度达到197°。该天线替换了某型无人靶机上传统的单极子天线,经过实测通信距离得到了显著增加,且通信无盲区更可靠。该天线结构简单,波束宽,剖面低,特别在高垂直面高速无人机机载通信与测控中有广泛的应用前景。In order to meet the design demand of conformal antenna on UAV（Unmanned Aerial Vehicle）, a nov- el wide beamwidth low-profile airborne conformal antenna is developed. Structure of L-shaped monopole antenna realizes low profile. Impedance matching and vertical polarization is realized by loading shorted pin. Quasi-om- nidirection radiation in horizontal plane is realized. 197 degree of 3 dB beamwidth in vertical plane is obtained. The antenna can be widely used on UAV for its advantages of simple structure, wide beamwidth and low profile.
