Generation of Sum and Difference Patterns of Linear Arrays Using Thinning
Abstract: Literatures are available on linear arrays with equal and unequal spacing. In this paper, the radiation patterns of linear arrays are numerically simulated using thinning. Thinning is a method by which the total number of active elements in a linear antenna array is reduced without causing major degradation in system performance. The present work is found to be useful in cost reduction while meeting some of the desired radiation characteristics …

Side Lobe Reduction using Bacterial Foraging Optimization
Abstract: AbstractTo meet the need for long-distance communication, the directive characteristics and radiation pattern of the antenna must be improved. By arranging the antenna elements in an electrical or geometric pattern, such that the radiated energy of the radiation elements vector added in the desired direction of propagation and canceled in the unwanted direction, results in a better-designed antenna array. The elements of the antenna array may be uniformly or non-uniformly …

Binary GA for Sidelobe Reduction and Null Steering in 5G Array
Abstract: This paper presents a comprehensive performance evaluation of a Binary Genetic Algorithm (BGA) for optimizing radiation characteristics of an active phased array antenna used in fifth-generation (5G) wireless communication systems. The primary objective is to achieve effective null steering while maintaining the desired main beam direction and simultaneously reducing the side lobe level (SLL). These improvements are essential for minimizing co-channel interference, enhancing spatial selectivity, and improving the Signal-to-Interference-plus-Noise Ratio …
