Abstract

In this paper, a broad band reconfigurable phase shifter designs utilizing composite right/left-handed transmission line (CRLH TL) metamaterials is demonstrated for X-band applications. Metamaterial unit cells are designed that allows seamless integration of active devices (varactor diodes) in order to achieve reconfigurability. Design equations and properties with arbitrary phase, band-pass characteristic, and dispersion/attenuation diagram are presented. To achieve broadband design, two metamaterial unit cells are cascaded together having resonant frequencies of 8.95 and 10.25 GHz. On average, 18-degrees of phase tuning are demonstrated over a wide bandwidth (~2 GHz) range with high linearity.
