A Wilkinson power divider with improved bandpass filtering and high isolation performance is proposed. These characteristics are achieved by replacing the quarter-wavelength transmission line in the conventional coupled line Wilkinson power divider with quarter-wavelength side-coupled ring (QSCR). Additional features such as DC blocking between arbitrary two ports, single-layer via-less structure for low-cost fabrication and convenient integration (as only one isolation resistor required) are highlighted. A 2-GHz Wilkinson microstrip power divider with a fractional bandwidth of 4% has been fabricated and experimentally characterized. The consistency between simulated and measured results validates the effectiveness of our proposed design.

Wilkinson Power Divider

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.

Wilkinson Power Divider

AbstractIn the design of a microstrip power divider, there are some important factors, including harmonic suppression, insertion loss, and size reduction, which affect the quality of the final product. Thus improving each of these factors contributes to a more efficient design. In this respect, a hybrid technique to reduce the size and improve the performance of a Wilkinson power divider (WPD) is introduced in this paper. The proposed method includes a typical series LC circuit, a miniaturizing inductor, and two transmission lines, which make an LC branch. Accordingly, two quarter-wavelength branches of the conventional WPD are replaced by two proposed LC branches. Not only does this modification lead to a 100% size reduction, an infinite number of harmonics suppression, and high-frequency selectivity theoretically, but it also results in a noticeable performance improvement practically compared to using quarter-wavelength branches in the conventional microstrip power dividers. The main important contributions of this technique are extreme size reduction and harmonic suppression for the implementation of a filtering power divider (FPD). Furthermore, by tuning the LC circuit, the arbitrary numbers of unwanted harmonics are blocked while the operating frequency, the stopband bandwidth, and the operating bandwidth are chosen optionally. The experimental result verifies the theoretical and simulated results of the proposed technique and demonstrates its potential for improving the performance and reducing the size of other similar microstrip components.

Good Agreement

In this paper, an ultra-wideband Wilkinson power divider based on the quarter wavelength transformation is proposed. The proposed power divider utilizes the resonance property of the four stage quarter wavelength microstrip stubs to increase the isolation between the to output ports. As the measured results show that, the power divider has the insertion loss less than 1.3dB with the minimum isolation 15.4dB in the working frequency range from 1GHz to 5GHz. The simulated results and measured results are in good agreement and the proposed power divider can be applied in the communication systems in modern electronic engineering.

AbstractIn this paper, a novel compact Wilkinson power divider with harmonics suppression using meandered compact microstrip resonating cells (MCMRC) at 2 GHz is proposed. In the design structure an open stub is used to suppress 2nd harmonic and two proposed MCMRC units are inserted into quarter wavelength lines of the conventional power divider to suppress 3rd–7th harmonics. The proposed power divider reduces the size over 65 % compare to the conventional one and impressively suppresses the harmonics (2nd–7th) with high level of attenuation. The proposed resonator and power divider are fabricated and measured. The measured and simulated results are in good agreements. The overall dimensions of the resonators and proposed power divider are only about 1.56 mm×9.2 mm (0.013 λg×0.08 λg) and 9.1 mm×13.1 mm (0.08 λg×0.11 λg) respectively.‎
