Multi-stable radiation pattern reconfigurable antennas
We investigate mechanically reconfigurable antennas as a means of creating flexible emergency communications infrastructure for disaster relief and low-infrastructure areas. Mechanical reconfiguration of conductors allows to create low-cost, energy-efficient, and lightweight solutions that can simultaneously adapt their performance to a changing environment. As such, we are studying reconfigurable helical lattice structures as a means of adapting performance in helical antennas. Our research is focused on several aspects:
- Investigation of the link between helix shape and antenna radiation pattern
- Integration of multi-stability into helical structures to enable low-energy reconfiguration
- Lightweight smart material actuation
- Manufacturing of novel composite materials that enable the desired multi-stability
