Description: A compact one-dimensional fixed phase shifter is presented in this thesis. The proposed phase shifter comprises metamaterial unit cells that consist of a host transmission line loaded with lumped-element capacitors and inductors, arranged in a dual high-pass configuration. Through periodic dispersion analysis, an effective propagation constant is derived, and design equations are presented for determining the lumped-element parameters for an arbitrary phase shift. Various phase shifters are fabricated and tested in coplanar waveguide technology at 0.9 GHz. It is demonstrated that the metamaterial phase shifters offer some significant advantages over conventional delay lines: they are more compact in size, they still exhibit a linear phase response around the design frequency, they are significantly more broadband, and they can incur a phase lead or lag as well as a 0&deg; phase. The phase shifters are well suited for broadband applications requiring small, versatile, linear phase shifters.
