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.

“…Nevertheless, the resulting circuitry area was comparatively large. Different kinds of stubs such as open stubs [12], delta stubs [13], and radial stubs [14] were introduced as an approach in designing modified WPDs with extended bandwidth. As such, extra transmission lines were integrated in the proposed techniques.…”

An ultra‐wideband (UWB) Wilkinson power divider with a notched band is presented. Multisection Wilkinson structure is utilized to realize UWB response. The notched band is introduced using the embedded dual‐mode resonators. The central frequency and bandwidth of the notched band can be adjusted independently by tuning the structural parameters of the embedded dual‐mode resonators. Even and odd analyses are used to analyze the proposed structure. The presented power divider has been developed and measured. The measured notched band is located at 1.78 GHz with an attenuation of greater than 14 dB. The measured results show reasonable agreement with the predicted ones. © 2014 Wiley Periodicals, Inc.

“…Moreover, they are printed on different layers of substrates which may increase the height, cost and fabrication complexity. Recently, a modified Wilkinson power divider with wideband performance has been proposed by adding open stubs [22][23][24]. Compared with the multilayer wideband power dividers, the modified Wilkinson power divider only use a single layer substrate while maintaining a wideband performance and occupying a compact size.…”

Abstract-An integrated eight-element antenna array has been proposed for ultra-wideband (UWB) applications. It consists of eight UWB antenna elements and an eight-way binary-tree modified Wilkinson power divider. Any two adjacent elements in the array are connected to each other and share a common side, thus leading to a connected antenna array. Moreover, this arrangement can be utilized to avoid grating lobe level at higher frequencies. Each antenna element comprises a square ring patch and is excited by a tapered balun to achieve low cross-polarization levels. In order to validate the design, a prototype has been fabricated and measured. Both simulated and measured results confirm that the proposed integrated antenna array achieves a good performance of a reflection coefficient below −10 dB from 2.9 GHz to 10.8 GHz, including stable radiation patterns with low side lobe and cross-polarization levels, thus the antenna is promising for applications in UWB imaging systems.
