| 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。 |

| Abstract: |
| In order to meet the design demand of conformal antenna on UAV(Unmanned Aerial V
ehicle), a novel wide beamwidth low-profile airborne conformal antenna is devel
oped. Structu
re of L-shaped monopole antenna realizes low profile. Impedance matching and ve
rtical polarization is realized by loading shorted pin. Quasi-omnidirection rad
iation in horizontal plane is realized. 197 degree of 3 dB beamwidth in vert
ical plane is obtained. The antenna can be widely used on UAV for its advantages
of simple structure, wide beamwidth and low profile. |
