Optimal Design of an Antenna Array

The technical aspects of optimal antennas are discussed and a solution is devised for the accompanying minimal problem. Optimal design is modeled as a special nondifferentiable minimization problem to reduce sidelobe radiation from a linear antenna array. It is found desirable to arrange the array so that the largest sidelobe is as small as possible, or by minimizing the radiation patterns of the array. Several examples are provided to demonstrate the efficiency of the technique, which is also applicable to digital filter, antenna approximation, and econometric problems.
