Antenna Array Design

alt text 

In an antenna array the outputs of several emitting antenna elements are linearly combined to produce a composite array output. The array output has a directional pattern that depends on the relative weights or scale factors used in the combining process. The goal of weight design is to choose the weights to achieve a desired directional pattern.
