A 1:6 unequal Wilkinson power divider

A 1:6 Unequal Wilkinson power divider is proposed. The proposed 1:6 divider has the microstrip line with 207 Omega characteristic impedance by adopting a simple rectangular-shaped defected ground structure (DGS). Instead of the previous meander-shaped DGS, the proposed rectangular-shaped DGS produces the transmission line having much higher characteristic impedance because of the decreased equivalent capacitance as well as the increased inductance. The analytic verification procedure for 207 Omega is also illustrated The measured performances show that the proposed 1:6 Wilkinson divider has excellent performances with a good agreement with the predicted ones.
