    • 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 ...
    • 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 ...
