Abstract:
Based on the two-section impedance transform character of the transmission-line,with open-circuit stub paralleling at each output port,a dual-band microstrip Wilkinson power divider with good isolation is designed to perfectly match any resistive load at two arbitrary frequencies.On the basis of even-odd mode analysis,the analytical formulas are obtained.The operating frequencies of the dual-band microstrip Wilkinson power divider are 2.0 GHz and 4.2 GHz.Measured results show that the transmission coefficients at the two operating frequencies are 3.5 dB and 3.8 dB,and that return loss and isolation are both better when the operating frequencies are 1.9~2.1 GHz and 4.1~4.3 GHz than when the frequency is 15 dB.
