A small-size ultra-wide Wilkinson power divider based on a new ring-shaped resonator using the PSO algorithm
We theoretically propose and numerically analyze a small-size Wilkinson power divider (WPD) based on a novel ring-shaped resonator that can create a wide bandwidth in the passband of the power divider. The WPD can attenuate 9 disturbing harmonics while the maximum insertion loss at the working frequ...

| description | We theoretically propose and numerically analyze a small-size Wilkinson power divider (WPD) based on a novel ring-shaped resonator that can create a wide bandwidth in the passband of the power divider. The WPD can attenuate 9 disturbing harmonics while the maximum insertion loss at the working frequency of 2.6GHz is about −3.08 dB. The structure consists of a pair of asymmetric cylindrical-shaped suppressors above and below the main transmission line. The overall dimensions of the structure are 8.5 mm × 11.8 mm, and the input return loss and isolation parameters are −41 dB and −17.3 dB, respectively, in the working frequency. Also, the fundamental frequency can be adjusted by changing the dimensions of the resonators and suppressors. The particle swarm optimization (PSO) optimization algorithm has been used to analyze and calculate the inductor and capacitor values of the equivalent LC circuit of the proposed WPD. In the passband (1.4GHz to 3.3GHz) of this power divider, the output return loss and isolation are less than −15 dB and the insertion loss is between −3.08 dB and −3.13 dB, so the fractional bandwidth (FBW) is 73%. The structure is compact and easy to be fabricated and has potential applications in communication devices. |
