Tunable Power Divider With Varactors Based Schiffman Phase Shifters for Antenna Arrays Beam Steering

Abstract : A tunable power divider appropriate for beam steering phased antenna array in the Ku band is designed in this paper. Varactors based Schiffman phase shifters are added to the power divider of four elements phased array. The proposed phase shifter generates a continuous phase shift variation by adjusting only one control voltages. Thus, the power divider can be able to steer continuously its beam with a maximum steering angle of 18.8° at 12.7 GHz. Various directions of the main beam are obtained by changing the diodes voltages.
