“…However, the presence of the intrinsically narrow bandwidth of the conventional WPD has turned out to be one of the major design challenges. A variety of modified WPD configurations have emerged over the years to cater to the needs of wideband, harmonic-suppressed, and multi-standard topologies [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Recently, the wideband WPDs have gained paramount importance in various applications such as power amplifiers [ 28 , 29 , 30 , 31 ], Hilbert transformer-based dual-band single sideband modulator [ 32 , 33 ], antenna arrays [ 34 ], phase shifters [ 35 ], and other RF front-end systems [ 36 ].…”

In this paper, a novel analytical design technique is presented to implement a coupled-line wideband Wilkinson power divider (WPD). The configuration of the WPD is comprised of three distinct coupled-line and three isolation resistors. A comprehensive theoretical analysis is conducted to arrive at a set of completely new and rigorous design equations utilizing the dual-band behavior of commensurate transmission lines. Further, the corresponding S-parameters equations are also derived, which determine the wideband capability of the proposed WPD. To validate the proposed design concept, a prototype working at the resonance frequencies of 0.9 GHz and 1.8 GHz is designed and fabricated using 60 mils thick Rogers’ RO4003C substrate. The measured result of the fabricated prototype exhibits an excellent input return loss > 16.4 dB, output return loss > 15 dB, insertion loss < 3.30 dB and a remarkable isolation > 22 dB within the band and with a 15 dB and 10 dB references provide a fractional bandwidth of 110% and 141%, respectively.

In this article, a general design methodology of a multi‐way compact equal split Wilkinson power divider (WPD) with bandwidth redefinition characteristics and planar structure is proposed. Quarter‐wave matching uniform transmission lines in the conventional design are replaced with non‐uniform transmission lines (NTLs) governed by a truncated Fourier series. Even mode analysis is adopted to obtain NTLs with predefined bandwidth functionalities; whereas several isolation resistors are optimized in the odd mode analysis to achieve proper isolation and output ports matching over the frequency range of interest. Compactness is achieved by incorporating only one quarter‐wave wideband NTL transformer, with a length computed at the center frequency, in each arm. Two 3‐way WPDs with different frequency bands (i. e., 5‐9 GHz and 4‐10 GHz) and one 5‐9 GHz 4‐way divider examples are designed and simulated. Furthermore, a wideband 3‐way WPD operating over 4‐10 GHz band is fabricated and measured. Results show input and output ports matching and isolation below −15 dB, and transmission parameters in the range of [–4.9,–6.2] dB and [–6,–7.5] dB across the operating band of the 3‐way and 4‐way WPDs, respectively.

“…Therefore, the investigation of the wideband Wilkinson divider is significant at this time. For this purpose, manly wideband power dividers [1][2][3][4][5][6] have been developed so far. But a few of them introduce the millimeter-wave wideband Wilkinson divider.…”

“…But a few of them introduce the millimeter-wave wideband Wilkinson divider. Normally, a multistage Wilkinson divider has an improved operation bandwidth over a standard single-stage Wilkinson divider [1][2][3][4]. According to the characteristics of the millimeter-wave Wilkinson divider, as the operat-ing frequency increases, the impact of parasitic parameters of the chip resistor will become tremendous.…”

“…In addition, the frequency reconfigurable antenna has other advantages over the wideband antenna, such as smaller size and more stable radiation pattern. Therefore, a great number of designs related to the reconfigurable microstrip antenna have been proposed in recent years [1][2][3][4][5]. For these designs, the frequency agility is achieved by introducing perturbation segments on the radiating patch to alter the resonant current path or by adding a loading into the feed structure to vary antenna input impedance.…”

A novel wideband branch line Wilkinson divider is proposed. Branch lines are introduced to replace multiple resistors used in the multistage Wilkinson divider to increase the bandwidth of a single‐stage Wilkinson divider. To demonstrate its performance, a modified single‐stage Wilkinson divider with four branch lines has been fabricated and measured. Results show that the measured input return loss, output return loss, and isolation are better than 12.4, 11.6, and 15 dB, respectively, across a 72% bandwidth from 18.8 to 40 GHz. © 2011 Wiley Periodicals, Inc.
