There is an increasing need for reconfigurable and deformable antennas and devices for high speed wireless communications and high-resolution sensing systems at millimeter waves. “Smart antennas” must have specific functionalities such as frequency agility, beam-steering, beam forming and polarization diversity. Conventional solutions for reconfigurable antennas are using active components or mechanical switches facing high cost, high loss, and complexity issues as the operating frequency increases. The objective of the project is therefore to propose new solutions of reconfigurable antennas based on the mechanical deformation of antennas and devices fabricated on ultra soft polymer substrates.
In this frame we have demonstrated the feasibility of low loss antennas at 60 GHz on ultra flexible substrates like polydimethylsiloxane (PDMS, Young modulus <5MPa), and we are developing reconfigurable antennas and phase shifters by integrating actuating structures, such as pneumatic, microfluidic or magnetic microsystems, for varying their geometric parameters and thus their operating characteristics.
