This paper presents Bacterial Foraging Algorithm (BFA) for the design of uniform linear antenna arrays for null steering by controlling only the element amplitudes. The BFA is a new evolutionary ...

where D is the diameter of the antenna ((N-1) × d for our uniform linear array) For a small array (small D) or a low frequency (large λ), the far field distance is small. But for a large array (or ...

The paper addresses the problem of pencil beam synthesis for large array antenna, such as the Ku/Ka-satellite receiving antenna. For such a problem, the conventional phase-shift-only algorithm would ...
