This paper presents the design of one dimensional broadband phase shifters based on a new class of negative refraction index transmission line. The proposed phase shifter here consists of conventional microstrip line and Negative Refraction Index (NRI) transmission line (TL) in which ideal operational amplifiers are applied to form the periodically loaded negative-impedance-converted inductors and capacitors. It is demonstrated that variations in inductors and capacitors can produce arbitrary phase shifts while maintaining the same overall length. Also, the NRI-TL is non-dispersive so that the new phase shifter can be used in many new broadband devices.
