Abstract

This paper introduces a millimeter-wave (mm-wave) phase shifters based on Gallium based liquid metal (LM), presenting an exceptional low insertion loss (IL) performance. The phase shifter can provide a measured phase shift of up to 180° with a precision of 22.5°. Operating within the 26GHz 5G band, this proposed phase shifter exhibits low IL, measuring below 1.6 dB at 26GHz and it achieves an outstanding figure of merit (FoM) of 117.1°/dB. Advantages of the proposed phase shifter include seamless integration with SIW-based feeding networks for mm-wave phased array antennas. Phase control is facilitated by liquid metal-filled vias, allowing for dynamic reconfiguration. Liquid metal is introduced into the via holes when needed and emptied when the via is no longer required. This reconfiguration approach holds promise for various reconfigurable mm-wave devices across a wide range of applications.
