我们提出了一种设计的高性能喇叭工作在700 GHz。该馈源由三个光滑壁圆锥部分组成，易于加工，但性能可与波纹喇叭媲美。测量的辐射方向图显示高的主波束圆度，低的旁瓣电平和良好的协议与理论预测。在140 GHz的频率带宽内，交叉极化电平低于−20 dB。新的设计允许制造高性能，大格式的饲料阵列便宜和快速。
We present a design of a high performance horn operating at 700 GHz. The feed, which comprises three smooth-walled conical sections, is easy to machine and yet has comparable performance to a corrugated horn. The measured radiation patterns show high main beam circularity, low sidelobe level and good agreement with theoretical predictions. The cross-polar level is below −20 dB across a frequency bandwidth of 140 GHz. The new design allows the fabrication of high performance, large format feed arrays cheaply and rapidly.
