In this paper, equilibrium optimization algorithm (EOA), which is a novel optimization algorithm, is applied to synthesize symmetrical linear antenna array and non-uniform circular antenna array (CAA). The main purpose of antenna array synthesis is to achieve a radiation pattern with low maximum side lobe level (MSL) and narrow half-power beam width (HPBW) in far-field. The low MSL here is an important parameter to reduce interference from other communication systems operating in the same frequency band. A narrow HPBW is needed to achieve high directionality in antenna radiation patterns. Entering the literature as a novel optimization technique, EOA optimally determined the amplitude and position values of the array elements to obtain a radiation pattern with a low MSL and narrow HPBW. The EOA is inspired by models of the control volume mass balance used to predict equilibrium as well as dynamic states. To demonstrate the flexibility and performance of the proposed algorithm, 10-element, 16-element and 24-element linear arrays and eight-element, 10-element and 12-element CAAs are synthesized. The MSL and HPBW values of radiation pattern obtained with the EOA are very successful compared to the results of other optimization methods in the literature.

使用平衡优化算法的线性和圆形天线阵列的优化设计

本文将平衡优化算法（EOA）作为一种新颖的优化算法，应用于合成对称线性天线阵列和非均匀圆形天线阵列（CAA）。天线阵列合成的主要目的是在远场实现具有低最大旁瓣电平（MSL）和窄半功率波束宽度（HPBW）的辐射方向图。这里的低 MSL 是一个重要的参数，可以减少来自工作在同一频段的其他通信系统的干扰。需要一个窄的 HPBW 来实现天线辐射方向图的高方向性。EOA 作为一种新颖的优化技术进入文献，优化确定了阵列元素的幅度和位置值，以获得具有低 MSL 和窄 HPBW 的辐射方向图。EOA 的灵感来自用于预测平衡和动态状态的控制体积质量平衡模型。为了证明所提出算法的灵活性和性能，合成了 10 元素、16 元素和 24 元素线性阵列以及 8 元素、10 元素和 12 元素 CAA。与文献中其他优化方法的结果相比，使用 EOA 获得的辐射方向图的 MSL 和 HPBW 值非常成功。
