Abstract EN
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.
