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° phase. The phase shifters are well suited for broadband applications requiring small, versatile, linear phase shifters.

Request PDF | A Compact Reconfigurable NRI-TL Metamaterial Phase-Shifter for Antenna Applications | This paper presents a compact reconfigurable phase-shifter based on negative-refractive-index. A compact metamaterial (MTM)-based tunable phase shifter consisting of four unit cells with a simple DC bias circuit has been designed at GHz. The variable series capacitors and shunt inductors that are required to be loaded periodically onto a host transmission line are realized employing only chip variable capacitors (varactors). In addition, the proposed phase shifter requires only one.

In this paper, a rectangular waveguide phase shifter is introduced in X band.

For frequencies from to GHz, this phase shifter gives a nearly. Appropriately designed metamaterial based phase-shifting lines are capable of providing arbitrary insertion phase, compact in size, and linear, flat phase response as compared to conventional transmission line delay lines. These phase shifting lines are usually operated in the NRI backward-wave region, to ensure that they do not radiate.
