“…Consequently, various efforts have been made to reduce the size while keeping or improving the basic properties of the divider. There are various techniques using lumped elements : a capacitive loading method , a high–low impedance resonator , an electromagnetic band‐gap (EBG) structure , and defected ground structure (DGS) . Those methods are highly suitable for size reduction, but WPD design in many previous studies have tended to rely on a rule of thumb and cut and try method because accurate design formulae have not been extracted or been too complicated.…”

This article proposes the stepped impedance line Wilkinson power divider (SIL WPD) and extracts the design formulae of SIL WPD. In the process of forming the WPD and executing a simulation based on the calculated design parameters, this study found that the SIL WPD improves stop‐band performance compared to the conventional one. In addition, it is useful in reducing the size due to the characteristics of SIL. Finally, the consistency of the simulated and measured results confirmed the validity of the SIL structure. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1607–1610, 2016

“…In [5], Defected Microstrip Structure (DMS) is used to prevent the leakage current through ground plane such as DGS, but it needs high resolution in fabrication. Planar artificial transmission line is presented in [6], High-low impedance resonator cells in [7], and Slow-wave structure in [8] which depends on reducing the group velocity of the propagated waves. All of the above techniques are based on intensive 3D EM simulations, while this paper adopts circuit analysis techniques having an advantage of providing helpful design equations and more precise results with reduced computational efforts.…”

This paper presents a novel compact Wilkinson Power Divider (WPD) that improves harmonics suppression. The proposed WPD consists of a shunt open stub between two series similar inductors, and a microstrip line between an isolation resistor and each output port. This configuration acts as a low-pass filter with two transmission zeros. In addition, it facilitates manufacturability by using lower transmission line impedance values than conventional structures. Through even and odd mode analysis, the general design equations have been derived in closed form. A 2 GHz microstrip WPD is designed, fabricated and measured based on the proposed technique. A great agreement has been obtained between the measured performance of fabricated WPD circuit and the simulation results. The measured results show that the second and third harmonic levels are about −46 dB and −36 dB, respectively. The proposed design has about 40% reduction in size better than conventional WPD. It achieves competing results compared to other published work.

“…Many researchers have proposed several techniques to reduce the overall size of the microwave circuits (power divider and couplers) [15][16][17][18][19][20][21][22]. In [15] parallel coupled line, composite right-/left-handed (CRLH) transmission line [16], electromagnetic band-gap (EBG) structure [17], [18], defected ground structure (DGS) [19], high-low impedance resonator [20], cascaded π-shape transmission lines [21], and dual transmission line [22], are used for miniaturization as well as harmonic suppression of microwave circuits. Recently dual-band PD was efficiently designed with high selectivity [23], based on port extension [24], combination of T-junction and step impedance line [25], however all the designs are having larger circuit size.…”

This paper presents a design of compact dualband Wilkinson power divider (WPD). The cascaded πshape and dual transmission lines are used instead of conventional transmission line sections of the reference WPD in order to miniaturize the circuit area. Therefore, 62% size reduction has been achieved without much affecting the performance of power divider. The insertion-loss of the output ports is within (3.4 ± 0.3) dB, for the reflection coefficient better than-15 dB and isolation better than 18 dB at the lower frequency band of 1.1 GHz. Similarly the insertion-loss is within (3.4 ± 0.3) dB, for the reflection coefficient better than-18 dB and isolation better than 24 dB at the upper frequency band of 2.55 GHz. The proposed WPD is analyzed, fabricated and tested. It is found that the measurement results are in good agreement with the simulated one.
