Summary
In this paper, the position-only, amplitude-only, and amplitude-phase synthesizes for the shaped-beam patterns of the linear antenna arrays have been achieved by using the clonal selection algorithm (CLONALG). The CLONALG is a relatively novel evolutionary optimization method based on the clonal selection principle of the human immune system. Numerical examples of the pencil, flat-topped, and cosecant patterns are given. Numerical results show that the CLONALG is capable of synthesizing the array patterns with a good performance both in the shaped region and in the sidelobe region.

Shaped-Beam Pattern Synthesis of Linear Antenna Arrays with the Use of a Clonal Selection Algorithm
1. Introduction
Antenna arrays are complex radiating structures used to obtain flexible radiation patterns. In general, antenna radiation pattern synthesis can be classified into three categories. The first is the pattern synthesis problem to produce a pattern having nulls in desired directions. The second is to produce patterns with narrow beams and low sidelobes. The third is to produce a shaped beam pattern. The shape of the desired pattern can vary widely depending on the application. The desired patterns are synthesized...See the full content of this document
