Based on year s practical working and designing experiences,the author gives a basic analysis of the four stack antenna,and discusses especially the design of the practically valued pattern shaping in detail.

The rebuilding method of reflector is proposed here to countet the situation that ribbing cross ariseson the doubly curved reflector with shaped beam,while the relflector is built through directly spreading metal net over the ribbings for an antenna with large aperture.

A phase controlled beam shaping algorithm based on analytic and iterative method is studied.

Genetic Algorithm(GA) has been shown to be an effective strategy in the off-line optimization,which is fit for designing shaped-beam antenna array.

This paper mainly studies the design and the shaped-beam technology of traveling wave antenna of rectangular waveguide with inclined slot on the narrow wall.
