Design and Demonstration of an Electronically Scanned Reflectarray Antenna at 100 GHz Using Multiresonant Cells Based on Liquid Crystals (2015, background): “In the literature, several unit cell geometries based on this tunable material have been designed and experimentally evaluated [2]–[8], which have led to the development of several different LC-based antenna arrangements [4]–[8].”
Reconfigurable Reflectarrays and Array Lenses for Dynamic Antenna Beam Control: A Review (2013, background): “The resonant frequency of a simple patch element also can be manipulated in a distributed fashion by varying the dielectric constant of the substrate, which is the operating principle of reflectarray elements using dielectrics with tunable properties such as liquid crystals [46][62][63].”
Design and Experimental Validation of Liquid Crystal-Based Reconfigurable Reflectarray Elements With Improved Bandwidth in F-Band (2013, methodology): “Difficulties in fabricating large MEMS arrays with independent voltage control have been reported in [11] whereas LC-based reflectarrays [14]–[17] are easy to manufacture and can provide electronic beam scanning at relatively low cost in these frequency bands [16], [17].”
Anisotropic Impedance Surfaces for Linear to Circular Polarization Conversion (2012, background): “Such a design could potentially be employed for the dynamic conversion of linear to LHCP or RHCP upon inclusion of a substrate with tunable permittivity (such as nematic liquid crystals [41]), or by using tunable high-impedance surfaces [42].”
