Adaptive Millimeter-Wave and THz Antenna Devices Based on Dielectric Elastomer Actuators

Pietro Romano

Dynamic reconfiguration of antenna devices is becoming a prime need in emerging telecommunication and remote sensing systems operating in the portion of the electromagnetic (EM) spectrum spanning from millimeter-wave (MMW) to terahertz. Different technique ...

Low-loss Millimeter-wave Phase Shifters Based on Mechanical Reconfiguration

Juan Ramon Mosig, Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Pietro Romano, Oluwaseun Adelowo Araromi

Abstract|We propose different concepts of mechanically recon¯gurable true-time-delay phaseshifters using micro-actuators at millimeter-waves (MMW). The mechanical reconfiguration allows to achieve phase shift reconfiguration with very low losses. One of th ...

Tunable millimeter-wave phase shifter based on dielectric elastomer actuation

Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Pietro Romano

A very low-loss tunable millimeter-wave phase shifter driven by dielectric elastomer actuators (DEAs) is presented. The device consists of a fixed coplanar waveguide (CPW) and two metallic loading strips suspended on an elastomer membrane. The horizontal o ...

Electromagnetic characterisation of flexible conductive membranes at millimetre-waves

Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Luc Maffli, Pietro Romano

Presented is the experimental surface impedance characterisation of stretchable conductors at Ka-band, using a non-contact technique based on two-port rectangular waveguide measurements. Two different types of metallisations are analysed, namely gold ion i ...
