Abstract:

 In this article, theoretical analysis and simulation of a wideband dual band balanced to unbalanced Gysel power divider using coupled lines are proposed for WIFI and 5G applications. The proposed power divider consists of three coupled line sections, one open stub, one transmission line section, 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 WIFI in cell-phone base stations, automotive industry, or any 5G applications.
