A reconfigurable 1:3 power divider is presented using quarter-wave long coupled lines and switches. The proposed power divider allows dual operating mode, or a 1:3 power divider and 1:0 power transmission mode, by turning the switches on and off. To make a high power-division ratio of three realisable and improve the bandwidth, a microstrip-slot structure is adopted on a thick substrate with high dielectric constant. The measurement of the proposed power divider shows good return and insertion loss performance in both modes.
