  • 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. ...

  • 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 ...

  • Pattern and Polarization Diversity Multi-Sector Annular Antenna for IoT Applications 

    Zandamela, Abel; Marchetti, Nicola; Ammann, Max J.; Narbudowicz, Adam (IEEE, 2023)
    This work proposes a small pattern and polarization diversity multi-sector annular antenna with electrical size and profile of ka = 1.2lambda and 0.018lambda, respectively. The antenna is planar and comprises annular sectors ...
