Slotted waveguide antennas with arbitrary radiation pattern

The well known Elliott's design method [ I t ] for muant slotted waveguide arrays is limited to the synthesis of pure real slot voltage distributions. In the present work this method has been extended to the w e of an a&ihary complex slot voltage distribution iueludiug the effects of mutual coupling. Comparison with full-wave analyses confirm the accuracy and computation efficiency of the method.
