“…Moreover, the result was verified, and the exact same results were found using the ABCD matrix by MATLAB. -36.3 & -28.4 -38.3 & -28.2 -34.61 & -47.49 In Table 2, the performance of the proposed divider is compared to the results reported for the dividers presented in (Zhu et al, 2020;Zhuang et al, 2018). The comparison is conducted in terms of the differential return loss, the isolation between the output ports, and the common mode suppression.…”

In this article, theoretical analysis and simulation of a wideband dual-band balanced to unbalanced Gysel power divider using coupled lines are proposed for dual-band WiFi applications. The proposed power divider consists of three coupled line sections, stepped-impedance stub, two grounded resistors, and a dual-band phase inverter. The dual-band phase inverter is used to perform the differential functionality at the input port. The use of the coupled lines results in a wide frequency range, compact size, flexible structure, and more freedom in choosing the design parameters. The closed-form equations and the ABCD matrix are derived using even and odd mode analysis and precise electrical design parameters are determined. The power divider was simulated at 2.4 GHz and 5 GHz, and great performance had been achieved; all ports are matched at the two frequencies with a 10-dB input fractional bandwidth of 45.83% at 2.4 GHz and 21.7% at 5 GHz. The isolation between output ports was more than 15 dB within the frequency bandwidth and the power was divided equally between output ports with the same phase. In addition, a perfect common mode suppression was reached, and the differential functionality was a success. Moreover, the device is simulated using Keysight-ADS and the results agreed well with the derived equations results. The device can be used for any application requiring dual-band WiFi connectivity.

In this paper, a design approach for getting dual-band working in a Wilkinson-based power divider (WPD) without adding any reactive elements or open- or short-circuited stubs is presented. The transfer matrix approach is used to get the analytical solutions of the required design equations. Admittance representation with respect to the input and output ports is done to perform even-odd mode analysis. In this impedance of each section is kept constant but the electrical length varies. Different combinations of electrical lengths are taken such that the overall length remains constant. The electrical lengths are selected based on dual-band analysis and depend on the tuning ratio. The conditions for attaining the impedance matching are applied to the obtained design equations and hence found out the values of the matching resistors to be placed between the transmission line sections. The proposed power divider centered at 2.5GHz and 7GHz is theoretically calculated simulated and fabricated. Finally, design procedures and experiments show good agreement with theoretical simulation.
