“…This approach avoids the series capacitor C in Figure 2. Similar even-odd mode analyses of conventional Wilkinson power dividers [1] and [34] can obtain the related design equations of the proposed divider (Figure 3). Figure 4 shows the proposed equal-split (3-dB) Wilkinson power divider configuration.…”

Abstract-This study presents new Wilkinson power dividers using compact stepped-impedance structures and capacitive loads to achieve the required power splitting. This approach can produce additional transmission zeros and effectively suppress the desired stopbands because shunt open stubs realize capacitive loads. This study proposes two equal-split dividers and two unequal-split dividers. For the first equal-split case, one shunt open stub forms the needed capacitor in each transmission path, creating one additional transmission zero in each path. To obtain one more transmission zero in each transmission path, the second Wilkinson power divider uses two shunt open stubs in each path to achieve the same capacitor value as the first divider. This study also tests unequal-split dividers with one and two transmission zeros in each path to confirm that compact stepped-impedance transmission lines and shunt-to-ground capacitors can be utilized in unequal power division.

Abstract-Based on the theory of microstrip-to-slotline transition, a series of power dividers with CPW-to-microstrip transition is developed. These power dividers can be made to be coplanar or noncoplanar structure, and the phase difference between the two output ports can be flexibly achieved in phase or out of phase. Two microstrip feed lines couple the energy from the two slots of the CPW with equal magnitude, thus realizing CPW-to-microstrip transition. An in-phase power divider and an out-of-phase one are designed, fabricated and measured. The measured results show that the power dividers provide good return loss, low insertion loss, and stable phase between the two output ports over the operating frequency band.

“…Moreover, N resistors are used to obtain good isolation between the output ports at the design frequencies. Based on Parad's theory [13], the even-odd mode analysis can be adapted to carry out the analysis. When two signals are applied at the output ports 2 and 3, with same amplitude and phase (even mode), the circuit can be modeled as two separate transmission line transformers [14], and the isolation resistors are open circuited as shown in Figure 2.…”

“…By applying the matching condition at the output ports, the values of the isolation resistors can be found. It is worth mentioning that in our analysis, it is assumed that the crosssectional dimensions of the microstrip/strip lines are relatively small with respect to wavelength, so that the effect of the discontinuities caused by corners and junctions on the performance of the designs is neglected [13]. The details of this even-odd mode analysis are presented in the following sub-sections.…”

Abstract-In this paper, a new simple design procedure of multifrequency unequal split Wilkinson power dividers (WPDs) is presented. The procedure is based on using N -sections of transmission line transformers, instead of the conventional quarter-wave WPD branches, to realize a WPD that operates at N frequencies. Good isolation is achieved by using lumped resistors without any extra modification to the conventional structure of WPDs. The analysis, design procedure, and mathematical expressions are presented for arbitrary design frequencies, and arbitrary power split ratio. For verification purposes, a 1 : 2 dual-frequency, a 1 : 2 tri-frequency, and a 1 : 2 quad-frequency WPDs are designed and fabricated. The measured results show good agreement with those obtained using the presented design methodology and with full-wave simulated results.
