| 摘 要： | 提出一种具有稀疏波纹结构的波纹喇叭天线，仅有2圈波纹，结构简单，易于设计加工。通过对天线参数的设计优化，可实现平顶波束赋形，在±40°的波束赋形范围内增益优于5 dBi，天线副瓣优于-30 dB，整个工作频段内驻波比(VSWR)优于1.8，适用于高轨卫星星间通信。通过对一个Ka频段样品的加工、测试和结果比对，验证了该设计方案的正确性。

| Abstract: | A corrugated horn antenna with sparse ripple structure is proposed. The antenna with only 2 ripples is simple in structure and easy to design and process. By optimizing the parameters of the antenna, a wide beam forming of ±40° and a gain above 5 dBi can be realized. The side-lobe levels are lower than -20 dB and the Voltage Standing Wave Ratio(VSWR) is lower than 1.8. It is suitable for inter satellite communication of high orbit satellites. Through the processing, testing and comparison between measured and predicted radiation patterns of a Ka-band sample, the correctness of the design is verified. |
