An ultra-wideband unequal-split Wilkinson power divider with a 2:1 split ratio is presented. To achieve the ultra-wideband characteristics, the conventional quarter-wave arms of the divider are replaced by tapered lines. Moreover, two extra tapered transformers are incorporated at the output ports for matching purposes as the designed divider is of an unequal-split type. To obtain good isolation between the output ports, five isolation resistors are used, the values of which are determined using the simple odd-mode analysis of the Wilkinson power divider. For verification purposes, an ultra-wideband Wilkinson power divider that operates over a frequency range extending from 2 to 12 GHz is designed, simulated, fabricated, and measured. The results of the full-wave simulation and measurements verify the validity of the design procedure.

“…In other publications [20,21] NTLs were used for designing dual-band and multiband power dividers. In this paper, the NTLs were subdivided into small sections, described by ABCD matrices and the ABCD matrix of the whole structure could be obtained just by multiplication of all sub ABCD matrices.…”

Abstract. Transmission lines are utilized in many applications to convey energy as well as information. Nonuniform transmission lines (NTLs) are obtained through variation of the characteristic quantities along the axial direction. Such NTLs can be used to design network elements, like matching circuits, delay equalizers, filters, VLSI interconnections, etc. In this work, NTLs were analyzed with a numerical method based on the implementation of method of moment. In order to approximate the voltage and current distribution along the transmission line, a sum of basis functions with unknown amplitudes was introduced. As basis function, a constant function was used. In this work, we observed several cases such as lossless and lossy uniform transmission lines with matching and arbitrary load. These cases verified the algorithm developed in this work. The second example consists of nonuniform transmission lines in the form of abruptly changing transmission lines. This structure was used to design a Chebychev's low pass filter. The calculated reflection and transmission factors of the filters showed some coincidences with the measurements.

Abstract-We propose a technique with clear guidelines to design a compact planar Wilkinson power divider (WPD) for ultra-wideband (UWB) applications. The design procedure is accomplished by replacing the uniform transmission lines in each arm of the conventional power divider with varying-impedance profiles governed by a truncated Fourier series. Such non-uniform transmission lines (NTLs) are obtained through the even mode analysis, whereas three isolation resistors are optimized in the odd mode circuit to achieve proper isolation and output ports matching over the frequency range of interest. For verification purposes, an in-phase equal split WPD is designed, simulated, and measured. Simulation and measurement results show that the input and output ports matching as well as the isolation are below −10 dB, whereas the transmission parameters are in the range of (−3.2 dB, −4.2 dB) across the 3.1 GHz-10.6 GHz band.
