  • Compact MIMO Antennas for Localization and PHY layer Security in Wrist Worn IoT Devices 

    Zandamela, Abel Abdul; Marchetti, Nicola; Ammann, Max J.; Narbudowicz, Adam (SFI, 2022)
    On-body IoT technologies, like wrist-worn devices, are becoming a key enabler of many cutting-edge applications such as connected healthcare systems (e.g, patient monitoring, in-hospital localization, sports fitness, and ...
  • 3D Beam-Steering MIMO Antenna for On-Body IoT Applications 

    Zandamela, Abel; Marchetti, Nicola; Ammann, Max J.; Narbudowicz, Adam (IEEE, 2023)
    In this article, a compact 3D beam-steering MIMO antenna operating at 5.75 GHz is proposed for on-body Internet of Things (IoT) applications. The planar antenna comprises a central patch and two concentric annular rings. ...
  • Small Dual-Band 3D Beamforming MIMO Antenna 

    Zandamela, Abel Abdul; Marchetti, Nicola; Narbudowicz, Adam (IEEE, 2023)
    This work proposes a small dual-band (2.4 GHz and 4.89 GHz bands) 3D beamforming Multiple-Input Multiple-Output (MIMO) antenna for emerging size-constrained Internet of Things (IoT) applications. The performance is realized ...
  • Compact Beamforming Antennas for Directional Modulation in IoT 

    Narbudowicz, Adam; Zandamela, Abel (2023)
    The paper discuss a PHY-layer security technique known as Directional Modulation (DM) and its implementations with compact beamforming antennas. The motivation is to allow DM to operate from small and low-complexity IoT ...
  • Non-Contact Radio Frequency Level Sensor Based on Wheeler Cap 

    Pratoomma, Prakorn; Zandamela, Abel; Narbudowicz, Adam; Chalermwisutkul, Suramate (2023)
    In this paper, we propose a novel non-contact liquid level sensor based on the Wheeler cap. The sensor utilizes an electrically small antenna operating at 276 MHz enclosed within a metal cap, in conjunction with the liquid ...
