  • 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 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 ...

  • 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 ...
