摘  要:本文阐述了共形天线的基本设计方法及其优点,设计研制了一种新型双频共形共孔径导航天线。该天线有两个射频输出端口,分别工作在L波段和C波段。通过分析对比不同形式的天线集成手段,最终提出一种性能优良的天线孔径综合实现方式并研制实物验证。仿真数据与实测结果基本吻合,在有效的工作频带和俯仰角为60°~95°、方位角为-45°~45°的角域范围内,L波段天线增益≥-1d B,C波段天线增益≥-2d B。The basic design method and advantage of conformal antenna are introduced in this paper. A novel design of dual-band conformal co-aperture antenna for airborne navigational application has been completed. This antenna operates at L band and C band with two RF output ports. A new realization way of antenna aperture synthesis has been found through the comparative analysis of different ways of antenna integration. The model of the antenna is simulated, and a prototype is fabricated and measured.The simulation and measured results are in good agreement. The gain of L-band beyond-1d B at the domain range pitch angle 60°~95° and azimuth angle-45°~45° and the gain of C-band beyond-2d B at the same time.
