Welcome to Reconfigurable Devices and Systems (ReDS) Laboratory

ReDS Laboratory focuses on developing radio frequency (RF) reconfigurable devices and exploring their applications in sensors, wireless sensor systems, and radar systems. We address interdisciplinary research challenges and create innovative solutions through novel system concepts. We investigate new microfabrication techniques and additive manufacturing processes for design flexibility and IC integration towards realization of novel phased antenna arrays, structurally integrated sensors, structurally packaged antenna arrays and electronics. Our work spans a wide frequency range, from sub-GHz to mmWave and beyond.

ReDS Laboratory is affiliated with the Center for Wireless and Informations Systems (WAMI) at the University of South Florida.


Examples of Current Projects

  • Structural PAA
    Structural Phased Antenna Arrays
    Employ additive manufacturing for PAAs to fully embed control electronics within the 3D structure while taking advantage of customized material layers in number, thickness, and properties.
  • LAS-based Antenna
    Lens Antenna Subarrays (LAS)
    A novel architecture that significantly reduces hardware complexity of traditional mm-wave phased antenna arrrays while exhibiting superior energy efficiency with near-identical spectrum efficiency.
  • Microfluidic mm-wave Switch
    Reconfigurabilty with Microfluidics
    Microfluidics and novel fabrication techniques are employed to achieve reconfigurability in a wide range of RF and mm-wave devices with significantly lower loss and high power handling capability.

 

  • 3D Packed + Integrated PUF
    Physically Unclonable Wireless Systems
    Employ additive manufacturing for structural integration of sensors and ICs within RF devices/antennas with randomized interconnects in order to create digital secret keys for wireless system security.
  • 3D packed BFIC with Thermal Feature
    Structurally Packaged Sensors and ICs with Thermal Management
    Additive manufacturing is used for structural integration of sensors and mm-wave active BFICs with antennas and features co-designed to aid in thermal management.

 

  • CAAs for RF Fingerprinting
    Chaotic Antenna Arrays for RF Fingerprinting
    Antenna element randomizations in locations and geometry + feed line length randomizations are employed as strong RF fingerprints. ML algorithms can detect these fingerprints with great success rate for device authentication. Moreover, the fingerprints can be employed for encoding data during wireless communication for physical layer security.
  • Wide-angle Zigzag LAS
    Wide-angle Beam-Steering LAS Antennas
    Fully 3D printed structurally integrated antenna elements are placed at the curved forcal surface of lenses. Lens intercoupling is further reduced with zigzag arrangement, providing a significantly larger beam-steering range with low side lobe levels from the LAS antenna which is significantly compact and energy efficient in contrast to traditional arrays and lens antennas.
