“…Transmission line metamaterials using the possibility of forward and backward wave propagation or the independent design of the phase and impedance [11][12][13], have a broad range of potential applications. Such artificial transmission lines can be designed with a large positive or negative phase shift making it possible to realize compact filters, phase shifters, and couplers [14][15][16]. Leaky-wave antennas with a frequency tunable radiation covering 180° including the broadside direction in its fundamental spatial harmonic have been demonstrated [17].…”

This paper presents a kind of broadband, lowloss tunable phase shifter based on transmission line metamaterial. An inherent high-pass backward-wave response property of a left-handed metamaterial based on coplanar waveguide (CPW) transmission line was used to realize a microwave phase shifter. The commercial software Ansoft HFSS was used to design and analyze for the transmission line metamaterial phase shifter structure, and the resulting S-parameters were used to characterize its performance. A transmission line metamaterial phase shifter was fabricated on Copper-Clad Board. The designed four unit-cells phase shifter provides a 0-190° continuous phase shift at 7.2 GHz using varactors biased from 0 V to 6 V with relatively low insertion loss.
