摘要
摘要:根据对马刺线的原理分析，该文提出一种新型马刺线结构，并在此基础上设计出一种新颖的超宽带功分器(频率范围为2.5～13.2 GHz)。该超宽带功分器尺寸较小，制作结构简单，带内传输特性好，输入与输出端口的回波损耗均小于–12 dB，带内插入损耗小于3.5 dB。在设计过程中，根据理想传输线模型，利用奇偶模分析方法，推导出设计的目标函数，并利用天牛须算法对其进行优化设计，有效提高了功分器的设计准确性和灵活性。为了验证设计的准确性，采用材料RO4003C作为基板设计超宽带功分器。实验结果表明，采用新型马刺线结构的超宽带功分器结合天牛须算法有效缩短了计算时间，提高了设计精度，可以广泛运用于超宽带功分器设计。

Abstract:Based on the study of the spur-line, a novel spurs-line structure is proposed. The design of a novel Ultra-WideBand (UWB) power divider is described based on the novel spur line structure for the 2.5～13.2 GHz frequency range. The designed device is compact and has a simple structure and good frequency response in the band. Its return loss insertion is less than –12 dB and its insertion loss is less than 3.5 dB. The equations used for the design are based on the concept of odd-even modes and transmission line analysis. The Beetle Antennae Search (BAS) algorithm is used to improve the efficiency and accuracy of the power divider design. In order to verify the accuracy of the design, a UWB power divider is designed by using material RO4003C as substrate. The results validate the feasibility of the spur line-based design and demonstrat that the BAS algorithm has a shortened running time and improved precision compared to other optimization methods. It can be widely used in UWB power divider design.
