摘要:

星载多波束天线是解决卫星大容量高速率通信业务需求的主要手段之一,多波束天线被广泛应用于各种卫星通信系统。对星载相控阵多波束天线、透镜多波束天线、常规反射面多波束天线和相控阵馈电反射面多波束天线等多种形式的天线进行分析,提出一种新型相控阵馈电反射面多波束天线,给出相应的设计方法,并研制原理样机进行验证。该天线具有收发共口径、阵列规模小,成本低,波束数量可扩展、可快速捷变,功率动态调用效率高,与平台适装性好等特点。相比二维相控阵天线体制,该天线可实现更多的波束数量;相比反射面多波束天线,又能实现全部波束的捷变扫描以及阵面功率93%~97%的集中调用能力。

Abstract:

Spaceborne multi-beam antenna is one of the main means to meet the needs of high-capacity and high-speed satellite communication services, and is widely used in various satellite communication systems.Various forms of antennas, such as spaceborne phased array multi-beam antenna, lens multi-beam antenna, conventional refl ector multi-beam antenna and phased array fed reflector multi-beam antenna were introduced.Here, a novel phased array fed reflector multi-beam antenna was demonstrated, the corresponding design method was given, and the prototype was developed and verifi ed.The proposed antenna has the characteristics of transmitting and receiving common aperture, small array size, low cost, scalable beam quantity, fast agility, high dynamic deployment effi ciency as well as good platform adaptability.Compared with the two-dimensional phased array antenna system, the antenna could achieved more beams.Compared with the multi-beam refl ector antenna, it could also realized the agility scanning of all beams and the centralized call ability of 93%~97%.

Key words: refl ector antenna, multi-beam antenna, phased array, ow-cost
