摘要

理论上设计了一种用于短波长(>700 GHz) SIS混频器的Pickett-Potter(1984, 1963)喇叭反射器馈源，并开发和测试了一个15 GHz的Pickett-Potter喇叭比例模型。天线由偏置抛物面反射器组成，由皮克-波特喇叭馈电。喇叭很容易加工，但仍然保留了波纹喇叭的理想电学特性，即低交叉极化，低副瓣电平和近圆形波束形状，尽管在减少的带宽上。计算基于模态匹配法和保角映射。

Theoretical analysis of the Pickett Potter horn-reflector antenna for submillimetre-wave applications

A Pickett-Potter (1984, 1963) horn-reflector feed for short wavelength (>700 GHz) SIS mixer has been theoretically designed and a 15 GHz scale model of a Pickett-Potter horn has been developed and tested. The antenna comprises of offset parabolic reflector fed by a Pickett-Potter horn. The horn is easy to machine, and yet still preserves the desirable electrical properties of a corrugated horn, namely low cross polarisation, low sidelobe level and nearly circular beam shape, albeit over a reduced bandwidth. The calculations are based on the modal matching method and conformal mapping.
