Electronically Reconfigurable Metasurface Antennas based on Liquid Crystal Technology

This contribution proposes the use of liquid crystals (LCs) for the realization of an electronically scanning antenna for SOTM user terminals based on a reconfigurable metasurface (MTS). The proposed solution is based on a periodic leaky wave (LW) structure, whose modulation period is changed dynamically to achieve beam scanning. Numerical results of a preliminary design for 1D scanning are presented.
