摘要

用尽可能少的元素合成天线阵列以获得期望的辐射方向图在某些应用中是重要的,例如,卫星通信,其中天线的重量是有限的。本文的目标是对同心圆形天线阵列(CCAA)进行减薄,以达到减轻重量和成本的目的。本文引入群智能技术——二元萨尔普群算法(Binary Salp swarm Algorithm, BSSA)来合成薄化CCAA。天线阵列的减薄需要在天线的延伸中排出一些天线,以获得与密集占用阵列相似的辐射特性。提出了BSSA方法来合成CCAA以降低最大旁瓣电平(MSLL),同时保持减薄百分比等于或大于50%。采用BSSA方法对440根天线的CCAA进行了优化,并与其他最先进的方法进行了比较,以证明其有效性。

Thinning of Concentric Circular Antenna Array Using Binary Salp Swarm Algorithm
Antenna array synthesis with the least possible number of elements for obtaining the desired radiation pattern is important in some applications, for example, satellite communication, where the weight of antennas is limited. The objective of this paper is thinning of Concentric Circular Antenna Arrays (CCAA) to achieve a reduction in weight and cost. In this paper, swarm intelligence technique, Binary Salp Swarm Algorithm (BSSA) is introduced for synthesis of thinned CCAA. Thinning of antenna array requires the expulsion of a few antennas in the stretch of antennas so as to attain similar radiation characteristics as that of a densely occupied array. The BSSA approach is proposed to synthesize a CCAA to decrease the maximum side lobe level (MSLL), simultaneously by maintaining the percentage of thinning equivalent or higher than 50%. A CCAA with 440 antennas is optimized by the BSSA approach and is compared with other state-of-the-art approaches to demonstrate its efficacy.
