Synthesizing arrays with low sidelobe and pencil
beam radiation profile is under investigation for decades. A
variety of array structures are available, but the simplest and
useful structure is that of a linear array. Here, two basic
symmetric Linear Antenna Array structures are assumed. The
required array structure is assumed to provide low sidelobe
and pencil beam profile. Departure from a uniformity in
current and location profile has shown quiet appreciable
improvement in the radiation pattern. The simulations are
carried out using Differential Evolution Algorithm employing
Best of Random mutation strategy (DEBoR).
