Microwave Wideband Constant Phase Shifter

A method of wideband constant phase control is proposed. This can be applied to reflection type phase shifter with p-i-n diode. Using the proposed method, a microwave phase network which consists of a transmission line and reactive circuit element is suggested. By determining theproper values of design parameters, the desired wideband constant phase with different specification can easily be designed. Also, using the proposed method, the parameters variation, and 1.1 dB of insertion loss in the range of 12% bandwidth.
