“…But, due to the high-frequency noise effect, the measured S parameters for the suppressed fifth harmonic have a fuzzy shift. Two triangular-shaped resonators, two open-circuit stubs, and a trapezoidal-shaped suppressor with a 68% attenuation and small dimensions are used in [6] to provide an ultra-wide PD. This WPD has a small size but is single-band and has limited applications.…”

In this paper, a new dual-band Wilkinson power divider (WPD) is designed and fabricated using novel low and high impedance stubs instead of quarter-wavelength transmission lines. The proposed circuit was analyzed using odd and even mode analysis, and the optimal values of design parameters were obtained using the particle swarm optimization algorithm. The designed power divider has input reflection coefficients (S11) of −22.1 and −17 dB at the first operating frequency of 2.2 GHz and the second operating frequency of 14.2 GHz, respectively. It also improves stop-band and fractional bandwidth (FBW) while maintaining a simple topology. The proposed WPD suppresses undesired harmonics from the second to the fifth with an attenuation level of less than −20 dB in the first band and generates a broad stop-band (4.4–11.5 GHz). In the first band, the FBW is 54.5%, and in the second band, it is 20.1%.
