In this paper, compact Ultra-Wide Band (UWB) 1:2:1 unequal split modified Bagley Power Divider (BPD) using Non-Uniform Transmission Lines (NTLs) theory is designed and tested. Based on this theory, 42.44% and 31.1% size reductions are obtained in the lower and upper λ/4 Uniform Transmission Lines (UTLs) in the first and second sections of the proposed divider. To evaluate the effect of the divider’s compactness on its performance, it is compared with UWB 1:2:1 unequal split BPD using Tapered Transmission Lines (TTLs). Both dividers show good results where the measured return loss is appeared to be S11 < −10.6 dB and < −13.4 dB for NTL and TTL BPDs, respectively. However, the insertion losses S12 = S14 and S13 are around −6 ± 1.5 dB and – 3 ± 1.3 dB, respectively for both dividers. In this study, simulations are carried out using High-Frequency Structure Simulator (HFSS) software. The evaluation of the proposed divider is obtained from the simulation and hardware measurements results.

使用非均匀传输线的紧凑型 UWB 1:2:1 不等分三路 Bagley 功率分配器

在本文中,使用非均匀传输线 (NTL) 理论设计并测试了紧凑型超宽带 (UWB) 1:2:1 不等分分割改进的巴格利功率分配器 (BPD)。根据这一理论,在所提议的分频器的第一和第二部分中,下和上 λ/4 均匀传输线 (UTL) 的尺寸减小了 42.44% 和 31.1%。为了评估分频器的紧凑性对其性能的影响,将其与使用锥形传输线 (TTL) 的 UWB 1:2:1 不等分 BPD 进行比较。两个分频器都显示出良好的结果,其中 NTL 和 TTL BPD 的测量回波损耗似乎分别为 S11 < -10.6 dB 和 < -13.4 dB。然而,两个分频器的插入损耗 S12 = S14 和 S13 分别约为 -6 ± 1.5 dB 和 – 3 ± 1.3 dB。在这项研究中,使用高频结构模拟器 (HFSS) 软件进行模拟。建议的分频器的评估是从仿真和硬件测量结果中获得的。
