为了实现对飞行目标的测控跟踪,设计了一种基于探针加载结构的具有倾斜波束的测控天线。该天线通过在圆形金属贴片上加载短路探针实现了波束调控。结果表明,该天线中心谐振频率为4.7GHz,在4.38GHz~4.9GHz频段范围内回波损耗小于-10dB。在水平面准全向辐射,在垂直面50°方向实现最大波束指向,可以满足对飞行目标的测控跟踪需求。该天线具有结构简单、波束调控易实现、剖面低等优点,在测控通信中有广泛的应用前景。
In order to realize the tracking and control of the flight target, a measurement and control antenna with a tilted beam based on the probe loading structure is designed. The antenna achieves beam steering by loading short-circuited probes on circular metal patches. The results show that the center resonant frequency of the antenna is 4.7GHz and the return loss is less than -10dB in the range of 4.38GHz ~ 4.9GHz. Quasi-omni-directional radiation in the horizontal plane, the maximum beam direction in the direction of 50 ° vertical plane, to meet the flight control and tracking needs of the target. The antenna has the advantages of simple structure, easy beam regulation and low profile, and has broad application prospects in the measurement and control communication.
