摘　　要：给出了波导裂缝阵天线实现恒指向的一种新方法——非等长度馈电法。按这种方法设计的天线,其结构简单、体积小、重量轻、加工方便、易于实现、可靠性高、电性能优良。通常所说的等长度馈电法,仅是本文方法的一个特例。A new method-unequal electrical path length feed method-has been developed to implement frequency independent beam pointing direction for waveguide slot array antenna. Tbe aerial made with this method is simpler, smaller and lighter, compared to those made with equal electrical path length feed method. It is also more reliable and easier to manufacture with good electric performance. Normal equal electrical path length feed method can be viewed as a special case of this new method.
