四个波导馈电最重要的特性是什么？讨论了波导孔径产生的/4扼流圈偏移。该馈源可用于深抛物面反射镜（F/D < 0.35）的照明，具有很好的E-H平面相等性和宽的模式带宽。
The most important characteristics of a waveguide feed with four ?/4 chokes offset from the waveguide aperture are discussed. This feed is useful for illumination of deep paraboloidal reflectors (F/D < 0.35) and shows very good E-H plane equality and broad pattern bandwidth.
