A 1:6 Unequal Wilkinson power divider is proposed. The proposed 1:6 divider has the microstrip line with 207Ω 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 207Ω is
