| Abstract: | 〗A 20-output Wilkinson power divider at S frequency is proposed.The 20 output ports Power Ratio is 1:1,and the characteristic impedance of input line 50.The structure is drawn by 3D-electromagnetic simulation software Advanced Design System 2009.The result shows that the proposed power divider demonstrates a good performance within the desired frequency range from 2.17 GHz to 2.20 GHz with the return loss less than -18 dB at 1.5 GHz and the output power and phase imbalances about 0.3 dB and 2° respectively.The isolation between the two outputs is with -25 dB isolation for the whole bandwidth. |
