    • Angle of Arrival Estimation Via Small IoT Devices: Miniaturized Arrays vs MIMO Antennas 

      Zandamela, Abel; Chiumento, Alessandro; Marchetti, Nicola; Narbudowicz, Adam (2022)
      This tutorial discusses the problem of Angle-of-Arrival (AoA) estimation from small Internet of Things (IoT) devices. It reviews the limitations and challenges of existing miniaturization strategies, which involve classical ...
    • Electrically Small Multimodal 3D Beamforming MIMO Antenna for PHY-Layer Security 

      Zandamela, Abel Abdul; Marchetti, Nicola
      This work proposes an electrically small 3D beam- forming antenna for PHYsical Layer (PHY-layer) security. The antenna comprises two layers of stacked patch structures, and is a five-mode five-port MIMO system operating ...
    • Energy-Efficient Physical Layer Security for Wearable IoT Devices 

      Zandamela, Abel Abdul; Marchetti, Nicola (2023)
      This work proposes an energy-efficient Directional Modulation (DM) scheme for on-body Internet of Things (IoT) devices. DM performance is tested using a 5-port stacked-patch MIMO antenna under two scenarios: free space ...
