本篇主要研究利用粒子群演算法將非均勻天線陣列最佳化，研究起因於佈設天線陣列是一件相當大的工程，若能在事前做有效的設計規劃模擬，就可以減少不必要的錯誤，讓不必要的人力與硬體成本皆減少，研究方法主要是透過粒子群演算法調整陣列元素位置，藉以最大化在主波瓣和旁波瓣間之峰值差，使天線陣列在發射端與接收端得到良好的通訊品質，以求防止不被雜訊所干擾，在此同時對頻寬作出限制，使得在接收良好的通訊品質的同時，也能顧及解析度與指向性。實際結果也顯示粒子群演算法，相較其他演算法來得優異，成功提升通訊品質，且不失解析度與指向性。
In installing antenna arrays of wireless communication systems, communication arrays are often optimized so that the side-lobe level is minimized. The goal is to reduce influences of interferences. Because building antenna arrays is difficult and expensive, optimization design by
computer simulation in advance is required. In this paper, we utilized the particle swarm optimization to optimize of antenna arrays. The side-lobe level of an antenna array is minimized by adjusting positions and exciting weights of array elements under the constraint of certain
beam-width limitation. The results show that techniques of particle swarm optimization can efficiently achieve optimize of antenna arrays.
